How to Use Underglaze: Watercolor and Opaque Techniques
Вставка
- Опубліковано 2 жов 2024
- This video is a step-by-step guide to using underglazes to add an illustrative design to your ceramics. I’ll show you how to create solid, opaque images as well as how to create watercolor techniques using underglazes. In this video I draw and paint flowers and whales onto a wheel thrown vase.
Underglaze is my favorite way of decorating my pots! I love getting lost in the intricacies of the design and the repetition of the layering. It is not uncommon for a single pot to take me several days and even weeks to underglaze. The watercolor technique not only makes a beautiful design, it also significantly cuts down the span of time it takes to finish the underglaze because it does not require as many precise layers.
This is my first video tutorial for clay and so I truly hope you enjoy it and will give me feedback!
Happy Day!

Great video and instruction! This, to me is a game changer!
Thank you so much! I'm so glad it was of use.
Amazing Dear Linnea , Thanks for sharing this useful video
Sasa afshine Dear Sasa, thank you so much for your kind words 💜
great instructions! Also, thanks for showing the finished product!
BB Jo thanks! It definitely prolongs the production time but the final product is always what I look forward to in tutorials! I really appreciate the kind comment.
Thank you. This was very well done.
This make so much sense ! Why did my teachers never told me to let the underglaze dry before aplying another layer ? No wonder all my paint jobs look blotchy... Thank you so much for this video ! By the way, what brand of underglazes are you using ? I use Duncan EZ stroke underglazes ( it comes in tiny little bottles... the one you are using seems to comes in such big containers ! )
Préséa some colors run thin as well. Our yellow is always a little blotchy. I use Amaco underglazes. I use their LUG brand white and their Velvet Underglazes for pretty much everything else. But each color reacts differently and it really takes time and practice getting to know each color and how it reacts. Our pink and amethyst are notorious for bad results. I mix all my pinks by hand. But I should also try other brands to find the best results. Good luck and I’m glad to help you where I can!
I am just getting back into underglaze since college. I was told that the underglaze can not be put on top of a glaze. Was the white you used an underglaze then? I have just gotten a set of 12 Amaco velvet colors, and then found Mayco Fundametal underglaze and would like to know if you can mix the 2 brands. Also, can each color be blended with another to create a different tone. @@MissLinneaLark
@@sondrahirssig6393 hi Sondra, underglaze can indeed ONLY go under glazes 😉. I mix Amaco underglazes all the time. Their LUG white is the best (I detest their velvet white, it bleeds and isn’t opaque). So you will prolly be ok? Maybe do a test first.
I have tried to mix speedball and Amaco and that did not go well.
I mix my own colors 100% of the time. I use little tubs with lids to organize them. I don’t love their purples and pinks and so I always mix them myself.
Good luck and thanks for watching!!
Awesome video, thanks for the tutorial!
Oh, I'm so glad you enjoyed it!
Well done!
Very informative.. however that repeated segment of repeated music was very distracting...
This is so helpful😭 you’re such a kind & generous person to share with us everything from scratch!
Lizzy is ur sleeping pills awww ☺️, Lizzy I’m so glad you found it helpful! It is my joy to pass on anything and everything I have learned. Good luck and happy New Year!! 🎊
Thanks so much for this video! Quick question - do you do 2 glaze firings when you use underglaze? One after the underglaze has been applied and then another once the clear glaze has been applied? If so, is you underglaze firing the same cone as the final clear glaze firing? Are you firing to cone 4/6? I have been wondering if doing 2 firings would help with surface issues and if so, what cone to fire the underglaze firing to. Many thanks! Your video is so well done and easy to follow. Thank you!
Ok! I have been reading other comments and want to check my research. If I usually fire glaze to cone 5/6, then using underglazes, I would bisque fire my pots to cone 04, apply underglaze, bisque to cone 04, apply clear glaze and any other glazes, fire to cone 5/6. Is that correct?
@@stonecottagepotteryfarm3189 I have never done it, but yes! That’s how I would do it. 😁
Thank you for the informative video. Your students are very lucky to have you as a teacher. I noticed someone asked this question, but I didn't see an answer. Could you please clarify, do you need to do the three layers of white underglaze, if your bisque-fired piece is white? I am new to pottery and the studio that I go to uses mostly white clay so I was hoping I could draw the designs directly onto the bisqueware instead of doing the 3 coats of white underglaze. Please let me know what you think. Thanks Linnea!!
When clear glazed, white clay turns a creamy buff color. I don’t like it (just my preference) 😂 so I always start with white. But as far as the color theory of it goes you’d prolly be fine. But also this pot was red clay so I covered it with white first.
@@MissLinneaLark Oh my goodness. Thank you for the prompt response. This is really helpful. I am taking another pottery class in the new year and I definitely find I struggle to get things done in 3 hour blocks. So if I can save myself from doing 3 layers of white underglaze that would be helpful. I really appreciate your help.
Great instruction but that background music is REALLY annoying!!! Geez!!!
LOL... all I can say is that it was my first video tutorial and I hope I'm improving ;)
Wow! Not only is your work beautiful but you are a born teacher. Your students are fortunate.
Hi there! thanks for this video. Are you painting on greenware or bisqueware? I wanted to try the water color technique, does it matter if it's applied on greenware or bisqueware. Do they give different results?
Tabitha Das hi! I am painting on bisqueware. You can apply it on greenware and that would save you a firing, the colors will look the same. Here is my process: Bisque Firing - Underglaze - Glaze Firing - Clear Glaze - Glaze Firing #2. You could also do: Underglaze Greenware - Bisque Firing - Clear Glaze - Glaze Firing. As a high school art teacher I decided that I would not allow my students to put underglaze on greenware/in Bisque Firings even though it's totally fine to do. The reason I made this rule is because there's always a kid who accidentally mixes up glaze and underglaze and that will cause problems, as you should never have glaze in a bisque firing. Just remember to always fire underglaze and then do a separate firing for glaze. This is because imperfections come out of the clay (and underglaze) during the first firing. When this happens, if you have glaze on the clay it will bubble up when the imperfections are released in the firing. This will cause bubbles and/or shards on your work. Hope this helps!
I would love to see yours when you’re done!
@@MissLinneaLark Hello, can i put underglaze on bone dry wares? Cann i still sand the work after bisque firing to make surfaces nicer? Will the design get sand away?
Fang Xu absolutely! That sounds like an awesome technique.
So pretty! Music is fine. Maybe volume down abit ,its almist competing with your voice. Have you seen th pottery videos by Earth Nation? Music is similar. Thank you for sharing your talents, is such a inspiration !
Raylene Gardner thanks Raylene! I’m gettin so much shade on the music 😂 I really appreciate your helpful comments and look forward to improving in future. Seriously, thanks for your help!
hey, thank you for this video ! very instructive.
So I have a couple questions, just to make sure I really understood :
- underglaze is only applied to clay that has been fired once, right ? is there a type of glaze that can be applied on fresh clay and fired with it ?
- can you leave underglaze without a top layer of glaze ? would it be chalky, or unpractical?
- can you apply the underglaze all over the work, is there a risk of it sticking onto the kiln shelf?
(I go to an open workshop in germany, and the lady in charge and I struggle to communicate on pointed questions :))
Olympe Silve thanks for the comment.
Underglaze is clay based where glaze is glass based. Because of this, underglaze is not food practical or water/dust proof without clear glaze on top. This is because the ceramic will absorb and leak any liquid or moisture in your food and then start leaking through your pot. Lots of artists choose not to put clear glaze on top of sculptural work as an aesthetic choice, but not functional pieces as it would not be safe for furniture without the clear glaze (glass) on top. If you choose not to apply glaze it will have a chalky appearance. Also, the colors will stay a little lighter.
Underglaze can be put on leather hard clay (green ware) or can be applied to bisque ware (ceramic, already been fired once). Underglaze is also recommended for low fire. In order for your pottery to be food safe you would have to use low fire clay with it or else you will get crazing (small cracks in the glaze everywhere). While crazing can be beautiful, it renders the piece not food safe because it will absorb and leak water or liquids.
You can get clear matte or clear gloss glaze. I tend to use the clear matte. I like that it is less reflective. Clear matte glaze should be applied in 3 light but full layers. If the matte glaze is applied too thick it can leave a while cloudy look. Almost like how school glue dries when too thick. Clear gloss is very easy to apply.
Because Underglaze is clay based you can put it on the bottom without it sticking to the shelf. But this can be nerve wrecking for the kiln operator because they will be unlikely to tell if it is underglaze or glaze. Mistakes can easily happen and sometimes my students don’t pay attention to what they are doing and put glaze on the bottom. So I won’t fire anything on the bottom of any pieces.
I hope this helps! I love the control and the illustrative quality underglaze allows me to decorate with. I am able to execute crisp and clear line work and edges without bleeding or fusing of colors. Good luck!!
@@MissLinneaLark thank you so much for this detailed answer !
@@MissLinneaLark yes, thank you!
Would it be ok/food safe to underglaze an entire mug (and even leave some exposed clay) and then only glaze the inside and lip which contact liquid? I fire to cone 6.
mokachino26 yes! As long as your lips or food don't interact with the not glazed portions.
This video is awesome. Thank you for being so clear, precise and informative. So far the best instructional video on glazing I've ever seen (youtube or otherwise) THANKS!
🙂
You should strain your glaze if it has grit in it.
I really appreciate your videos. New subscriber. The background music is extremely distracting.
Thanks Annie. This was my first ever tutorial and there are so many mistakes, most especially the music! 🤣 Was it the music in all the videos or just this one especially? Audio is definitely not my forte and specific feedback really does help me make improvements in future vids 💕 thanks!
@@MissLinneaLark I’m older and have age related hearing loss. Any background noise makes it very hard to make out spoken words especially if I can’t see the speaker’s lips. I didn’t realize how much I relied on reading lips until recently. I guess I must have adapted over time. I haven’t watched all your videos yet but I think part of the distraction in this video was that the same 4 bars played over and over in a loop. Your instruction was very good and easy to follow. I don’t think I ever heard anyone else stress that 3 coats of underglaze was very important. Seems like it’s vital to a good result. I would not have guessed this was your 1st video. Keep up the good work!
@@mavisdavisify thanks for your thoughtful encouragement and articulation!
Hi! I hope you'll see this. did you bisque fire this? before glazing or under glazing?
yes, it had already been fired :D
Thank you for such a clear and informative tutorial. I realize this is an older post but if you happen to see my question I would be very grateful to know why you fired two separate glaze firings rather than putting your clear coat on top of the underglaze and fire together, or were you painting on greenware?
Thanks!
Hi @WENDYCummings, I always fire underglaze before glaze because the gasses in the UG release during the firing and can cause glass bubbles if there is glaze on top.
Great Video! What brush and glaze do you use for your lining? I saw it was Amaco glaze... is that the black outline as well? So Helpful!!!
Hi Marci, the brushes are "Chinese Watercolor Brushes." Here's a set off of amazon: www.amazon.com/Professional-Chinese-Art-Brush-Paint/dp/B01FSAT372/ref=sr_1_6?crid=1TDS1587NAM6H&dchild=1&keywords=chinese+watercolor+brushes&qid=1601255203&sprefix=chinese+watercolor%2Caps%2C254&sr=8-6
All the underglazes are Amaco low fire underglazes. Good luck!
Thanks so much for sharing! Do you ever have issues with applying too much underglaze? (PS I didn't mind the music 😄)
You’re welcome, Laura! I have never had issues with too many layers and I do a LOT of layers! Just make sure you wash off any dust before you begin.
im trying to learn how to do ceramics at home, and this is one of the most helpful videos iv'e come across! tysm! just a few questions if you don't mind, in regards to cones, what cone level is best for underglazes (that is also food safe)? and when purchasing underglazes, do we have to pay attention to what cone it falls under (for example, if I'm using cone 5 clay, do i have to purchase a cone 5 underglaze and then a cone 5 glaze?
An underglaze is not food safe. You have to put a glaze over it and a higher fire glaze for it to be food safe. I don't know enough about your other questions to give you an answer. Maybe someone will come along that can answer them for you.
The easiest answer is that underglazes are totally fine to use with food ware but it must be covered with a glaze. I use Amaco’s clear matte. But their clear gloss is great as well. You can even cover it with a colored glaze but I tend to prefer a more transparent glaze so you can see the effects of the underglaze. For example… if you put down yellow UG and cover it with a transparent blue, you will have a more greenish blue as yellow and blue make green. 🤩
The velvet underglazes can be fired between cone 06-10! So you can use it on pretty much most types of clay. However the look, thickness and consistency changes at different heats. But give it a try.
I do low fire only just because I only have one medium sized kiln and the faster firing times are good for our studio.
The main thing to consider when using UG is that the clear glaze you cover it with is the same cone firing as the clay. If they are not the same cone firing they with expand and shrink at different rates and the glaze will “craze” which is when there are cracks all over the glaze. It is pretty, but will render your piece not food safe or waterproof.
I hope this is helpful and that you enjoy the beauty of underglaze!! 🌞
Hi!! How can we make underglazes? (Pigments and flux?) Thanks!! Beautiful work!
Orgánica Bowls I have never made my own. But here is an article: ceramicartsnetwork.org/daily/ceramic-supplies/ceramic-glazes-and-underglazes/make-underglaze-ceramics-studio/
Wonderful step by step. I can tell you must be a great teacher!
Heather and Joe Garrison thank you so very much! 💗 your comment has made my day!!
Excellent video teally helpful bt where can i get this underglaze paint??? Just recommend ne some brand name
Amaco is a great brand. I order from Dick Blick, but you can prolly order online directly through Amaco. Sometimes you can get them through amazon. I usually prefer their Velvet Underglazes, but in some colors I prefer their LUG line (white is better with LUG). Also, they are meant to be used with lowfire clays and underglazes, but can be used with different results at different temps. Good luck and thanks for the interest!
Hello! Thank you for sharing!
I,d like to ask you some questions, please.
1. It is earthenware?
2. Only I have used Duncan and Mayco for earthenware. This brand Amaco is similar? Could I use it for earthenware?
3. If I need a base color that is not solid or so defined, 2 coats is ok? When you applied the color with water, watercolor effect, did you use two coats, too?
Thank you! Lovely work
It is earthenware, you can totally use it. If you do not want your base coat to be patchy, 3 coats are necessary. I have been lazy and tried 2 coats and always regret it! The watercolor effect can have any amount of layers. If you only place one layer down, it will be barely there. In this video some of the petals have areas of only one coat. You can layer as much as you like, but if you put a ton of layers down, eventually it will look solid(opaque) and not transparent like the watercolor techniques. On my pot, the areas of darker colors have more layers and look less transparent because there is more and more pigment (underglaze) in those areas.
I hope this helps! In the next few days I will be putting out another vid on underglazing. It will prolly help. Good luck!
@@MissLinneaLark thank you!!! you are very kind!
Question: What will happen to the underglaze if we don't apply the glaze over it ?
Awesome. Great video! Did you start working on a piece that was already bisque fired or bone dry?
I work on clean 🧽 bisqueware.
I have a questions could you have added a transparent yet shiny glaze at the end instead of the matte glaze? if so, which one do you recommend?
Absolutely! I use Amaco Clear Gloss glaze. It tends to go on thin so I always advise 4 coats. Gloss glazes rarely turn milky like matte glazes so it’s better to put them on a wee bit thicker. Good luck!
Hello ! and thank you from New Zealand for your super video, it really makes me want to get cracking! I am confused though,..what temperature did you glaze fire the bisue, and then temp for the whale UG? I have been taught to apply UG either to raw or bisque, fire at bisque, then only one GLOST firing, whether UG was applied raw or bisque. You are firing three times. Doesnt that first glaze you do in order to fire the UG color on,mean that its harder to make the clear coat stick onto an already glaze-fired object? [i.e. what would the clear glaze adhere to if it has already been vitrified once before?] hope you can help. this has often confused me! Hedy
I use low fire glazes and so my bisque firing and glaze firing are both to cone 05. As far as the glaze adhering to the underglaze, there is no difficulty there. Underglaze is just colored clay. When fired at low fire temperatures, underglaze doesn't vitrify, neither does the clay. So the clay and underglaze are both still porous and easy to apply glaze on top. At hotter temperatures clay and underglaze will vitrify and become waterproof. The only way to make low fire ware waterproof is to use glaze, which is what I do. I hope this helps!
Certainly does! hey, thanks a bunch for your prompt, expert reply :-) Now I see how it can happen, i'm mid-firing , glaze Cone 6. So cool of you!. Will check into more vids :-)
I learned that when water coloring, layering shouldn't be exact and with crisp edges
Can I use the underglaze on my bisque and then put the clear over that and fire at cone 06? Or do I have to fire the black underglaze at cone 04, and then clear glaze it at 06? I would like to avoid firing three times.
I'm using the black glaze as a wash to bring out the details in the texture of my piece, so I have to apply it to bisque to avoid wiping off the details.
You need to fire underglaze and glaze separately because the underglaze is clay based and all the gas and impurities release in the first firing. If you have glaze on top and are firing both together, you will get little air bubbles in the glaze that often times pop and are little shards of glass.
If you want to get 2 firings the only way to do that is to put underglaze on your greenware. That will take care of the bisque and the underglaze and then all you need is a glaze firing. Just be careful you don’t roughly handle and snap your greenware.
Hope this helps! Good luck!
@@MissLinneaLark thanks! If I'm using the underglaze as a thin wash for shading, could I get away with it?
Would Stroke and Coat work under clear glaze?
@@DonaldDrennan if it is very thin, maybe. Sometimes I risk it 😎 and sometimes it back fires.
beautiful great job!!!
Isabella Niven thanks baby
Was this piece bisque fired before you started with the underglaze, or is this greenware?
It is bisque ware, it had already been fired once. :)
Wow I learned so much!! Thank you!! 👌🏻👌🏻
I am overjoyed! Thank you and happy underglazing!
Did you apply the underglaze to greenware or bisque
Loved the video. New potter here. Do you really have to bisque fire it twice? Could you just put the clear coat over the painted piece and fire it once? And suggestion, if you’re going to use music, pick a track that has a much longer loop than about three seconds. It will be nicer on the ears. Also, the volume could be turned down so it’s not so distracting. ❤
😂 this was my first video tutorial and your music suggestions have been hopefully fixed! It’s the one constant bad criticism I get on here. Lol
In my experience, you can easily put underglaze on greenware… however 8/10 times students try it they break their pots because they forget how brittle it is 🫣.
When clay goes through it’s first firing, it releases a lot of gas as it burns out of the clay. Underglaze is made of clay and will do the same thing. If you have glaze on top then it can create glass bubbles on the body of your work. You could probably fix this with your firing, maybe make it longer, but for a school environment and the amount of work we have to produce, it just doesn’t make sense. Also, longer firings could cause other issues with glazes running, etc. I never let my kiddos fire underglaze & glaze at the same time on the same pot. Hope this helps 😄
Hello, from Malaysia. I like reading about pottery especially about majolica. I am very curious to know more about underglaze to produce food safe products and get same result like majolica. Finally, I found your video that answering all my questions. Thank your for kindness to share this technique.💐
Was this glazed on green ware or bisque?
bonnie garson You can do it on either. But I did it on bisqueware.
New to ceramics and gr at learning
This was so helpful and your work is just so beautiful. What brushes do you use? I’m in the market for some better ones and those look great! Thanks again
I usually enjoy bamboo watercolor brushes or the littlest, cheap detail brushes I can find.
Great video, but the 4 bars of intro piano music repeated 50000 times drove me nuts. Find some nice Erroll Garner and play the whole song.
LOL if youtube would give me .04 cents for every complaint about this music, I might make more on the complaints than on the royalties! hahaha Thanks for your honest feedback
Beautiful work! I'll be looking out for the next video and thank you for sharing your talents!
Thank you so very much!
hi, i really enjoy this video, and thank you so much for all the information you shared, it's one of the most useful I found on youtube regarding this subject. thanks again!
you could leave the computer music out
Just wanted to check with this bone dry or best fired where they are painting? Do you do two glaze firing or when you said the first glaze is at like a bisque?
I find there’s less chance of shivering when painting on bisqueware. So I usually bisque fire, paint on underglaze, fire again (underglaze can go in a bisque firing or glaze firing), glaze pot then glaze fire. So 3 firings in all. Hope that helps.
I just find your channel and it's really good . I'm new in the world of ceramic I would like to now about underglaze ❤❤
I was disappointed that you didn't explain the brand or type of underglazes and did you use a clear glaze without zinc??
I used Amaco Clear Matte Glaze 🤪
Good video! I only didn't get if it's on greenware or bisque? Thank you so much.
Bisqueware
Did you start with a bisque fired piece? Then do a glaze fire twice? So the piece was fired three times?
Correct! You can underglaze on greenware also. And that would be 2 firings.
This is a great and helpful video. Just curious... are you still and art teacher?
Yes 🤩 I’m still an art teacher. The past 2 years have been pretty intense for teachers… and students, and so I’ve done less video editing. But I’m hoping this year I can do more. Thanks for watching!! 💗
Great Video!!!! Look forward to seeing many more ❤
Cats*in*a*cradle Thank you so much!! I am creating another one on the creative process right now. I am new to UA-cam and am trying not to be a perfectionist, and I’m losing that battle 😂. I am hoping to finish it this month! Since I teach Art, Clay Sculpture and Pottery the videos will probably shift between those 3 subjects. I hope people don’t mind a variety! Thanks again!! 💗💗💗
Is your beginning piece greenware or bisqued? What cone or temp is the first firing? Second firing? I've done test tiles in my class but they appear "burn't". Greater than cone 4 or 5?
I started on bisqueware fired to 05. Then underglazed and fired again to 05. The clear glazed and fired again to 05. 100% low fire. But you need to be sure your clay and clear glaze is both low fire or else you can have problems with crazing or shivering.
Also, make sure you're firing to cone 04 or 05, rather than 4 or 5 (ceramicartsnetwork.org/images/default-source/uploadedimages/wp-content/uploads/2014/07/kilnfiringchart.jpg?sfvrsn=ec095b44_0)
Hi Miss Linnea! I love your video, thank you!
I wanted to know what cone you’re firing to? I’m in a class will only high fire to cone 10. I was wondering if the colors would stay that brilliant at cone 10?
Danette Riemer we fire at 05-04. All low fire. But the velvet underglazes work at high fire but with a different look. They look more like glaze when high fired. I have never fired ours that hot, however I’ve seen the effects and it’s kind of cool but very different.
Thank you! I’ll give it a try!
hello I'm new on pottery and ceramic things, I hope you can answer me. What that white layer you using? is that same like other color? is that glaze ?
The colors are Amaco Velvet Underglazes and the white is Amaco LUG underglazes. Both are underglaze and work the same way. I just find that the white LUG is less patchy and so I prefer it over the white velvet underglaze.
@@MissLinneaLark Thank you for answering 😁
This is awesome. I'm hand building with a high fire stoneware because I need a very sturdy clay, yet I want to paint on the surface. I love your tutorial. It's very helpful. So for firing, are there any high fire underglazes? If not, which underglazes do you recommend? And how high do they fire? Also, what paintbrushes do you recommend for fine detail? Ty
Hi Erica, you can use amaco velvet underglazes with high fire. I have never done it but one of my students brought me an example once. The underglaze looks different at high fire so I would do some test tiles and see how you like it. And there is no need to clear overglaze unless it is for food ware or you want to. That’s because the clay will vitrify at that heat.
My favorite underglaze brushes are Chineese calligraphy brushes because the are so absorbent. They make them in all sizes. But for fine details you might just use tiny cheap synthetic brushes. Their bristles are absorbent but also stiff so you can get a thin line.
Was the underglaze and design applied to greenware or bisque?
Bisqueware
I'm new to glazing, but want to learn everything about it. Can you please tell me if Before you did the under glaze, had you fired it? Is an under glaze different from a glaze? Did you make the lines with glaze?
Hi Colleen, underglaze and glaze are very different. Glaze is liquid glass and underglaze is colored clay. Because underglaze is clay based you can use it on greenware (leather hard or bone dry clay forms) or on bisqueware (already fired once). I usually choose to underglaze on bisquware because it is hard. It seems like anytime I try to underglaze greenware I end up breaking or chipping it. Bummer!
In this video I had already bisque fired the vase.
Glaze should only be used on bisqueware! If a piece is going to explode or break it usually happens during the first/bisque firing. If a piece has glaze on it and it explodes the glazed shards will attach themselves to other pieces in the blast radius. So only use glaze on already fired work. This happens because the glass in the glaze gets cherry hot and will attach to anything it touches.
Also, the first lines are just pencil which will burn out when you fire it again.
Good luck!
so I thought that Duncan Concept under glazes were to be put on green ware then after applying 3 coats it would go to bisque firing . My question is should this underglaze be applied after Bisque firing ? thank you
Corinna Amco underglazes can be applied on greenware or bisquware!
Thank you for your nice video. What brand of white base undercoat did you apply? Is it ok to paint images directly onto light colored bisque?
For white I use amaco LUG underglaze. Which is only low fire. You can get their velvet series but it’s always been kinda see through, so I don’t use it. But I use velvet for basically everything else.
Great instruction. The "music" made me want to tear my head off
LOL, noted :D Sorry and trying to do better!
I totally agree. Music was not necessary. Especially THAT music. Good instruction though.
Beautiful 😍 what's the material you used for glazing the object? Excuse my dumbness couldn't get it rightly 🙂
I am painting the design with underneath. After I fire the underglaze (colored clay), I put 3 coats of Amaco’s clear matte glaze. It goes on white but then becomes transparent when fired.
I hope that helps. Thanks for the kind words. Good luck!
Ma classroom...
Mad Rose awwww, I can’t tell who you are by your name and pic, but I’m so glad you think of “my classroom” as your classroom!! It warms my heart because I’ve tried to make it into a home full of love, creativity and safety for all of you!!
You're lucky to have this great teacher! :)
hello! i have a question :) why not dip the vaze into a clear matte glaze after finished underglazing and doing it with the brush? thanks :)
Charalambos Kouloumis, hello! You can totally do that. The matte clear glaze tends to go on too thick if you dip it. It’s a temperamental glaze and fires milky if applied too thick. Also, our school is small and doesn’t currently have room for buckets of glaze. If you decide to use clear gloss glaze, dip away!
Did you start with a greenware or bisque fired pot?
You can start with either. But in this video I am painting on bisqueware.
I was taught that underglaze can peel off if painted too thick? is that not the case? she would have 9 layers of underglaze in parts here!
I have only had underglaze come off once and that was from my own miss use and that was from a combo of thermal shock and not dusting my work. I very rarely have so few layers, as I usually do not use this watercolor technique and have never had issues with it coming off. Here's a video where I use way more layers: ua-cam.com/video/Q815hQYScj8/v-deo.html.
I know underglaze used to have way more restrictions and has come a long way (thank you scientists!), and some people aren't aware of the new abilities. For example you used to only be able to use it on greenware. But now one can use it on bisqueware as well. I hope that helps!
Thank you for this video! It was super helpful as I am just learning to watercolour my ceramics. Also, I love the decor you chose to paint, it is such a pretty vase!!
Thanks Cara! I'm so glad to help in any way and good luck with your watercolored designs!
Did you apply it on greenware or bisquewear?
Bisqueware
Awesome. Thank you this was very interesting. A beautiful finished product 😊
@Sylvia Hodgson thank you so much!
Is there any precautions you should take when using underglazes? I'm worried that I might be breathing in silica dust that comes off when I erase or do scraffito. Is this a possibility?
Peachy Peacock If anything is Turing to dust and in the air you breath you should always wear a mask. I have never had that problem with underglaze because it doesn’t usually turn to dust. If you are sgraffito-ing, it should be leather hard or near it, so it wouldn’t turn to dust. Just use your common sense about wether or not it is going in your lungs. There are chemicals in the underglaze but nothing should ever go in your lungs so the chemicals are kind of a moot point. Wear a mask if there is dust! 😄 as far as breathing the smells of underglaze, it is not dangerous, although they do smell TERRIBLE! Especially the reds! Lol I just tell my kids to suck it up and stop whinny-baby-ing. LOL, but it is terrible.
@@MissLinneaLark oh yeah I guess I was just talking about the little fall outs that happen from from scraffito. I'm not really sure if the fall outs are going directly toward me to breath in but I guess I was just worried they might be since they get dispersed in the air. I think I'm just overly worried about silicosis.
@@peachypeacock6621 Thats a good thing to worry about! but I think it is mainly of worry when it is dust???
@@MissLinneaLark yeah. But the fallouts from scraffito are like dust form. Right? Is that what dust form is?
Peachy Peacock in my experience it carved off in clumps. I would not worry about chips or clumps. If the clay is bone dry completely it could get dusty. In that case you might want to wear a mask. But , like I said, sgraffito is more of a leather hard process. I really think you will be fine without a mask. If you inhale dust and start coughing, that’s a good sign to put on a mask.
What is the clay body and at what cone did you fire for the glaze firing? This information would be helpful.
Low fire for both
Miss Linnea Lark what’s the clay body? I personally only work in porcelain, cone 06.
@@raquelasandino5825 It's called Spirit White. It is a lowfire stoneware clay body. The underglazes are made for lowfire. www.clayimco.com/product/spirit-white-leslie-ceramic/2
I love the whales so much !!!
Thanks Anna! They love you too, and so do I :D
That's soooooo beautiful, thanks for sharing :) :) :)
You are so welcom! :)
Did you apply the underglazes on to a pot that has been bisque fired, or to a dry pot, before its bisque fired?
Either will work, but this is on bisquware.
Is this slip on Greenware? Or is it white (under)glaze painted on biscware, ?
It is white underglaze painted on bisqueware :D
Queen ur famous ;)
hahaha and I shall go down in history as the messiest teacher desk of all time!
What brand of clear matte glaze are you using? It looks great and not cloudy.
Tiffany Parker I’m using Amaco low fire clear matte glaze. The tricks are to:
1. keep it on the runny side by adding water
2. Strain it before every use
3. Apply one thin but full layer at a time.
4. Suck up any excess glaze that doesn’t dry quickly and starts to puddle. ESPECIALLY in carved areas or corners.
5. Wait for each layer to dry before you apply the next.
6. Only apply 3 layers
7. It’s recommended a firing at 05-04. 04 actually makes the glaze less cloudy. Just be careful because other low fire glazed will run at 04.
Good luck!!
Linnea
I love your videos! You are a great teacher.
Donna Davies thanks so much!!
Thank you! I wish i could free hand draw like this! Beautiful whale 🐋
I plan on making more drawing tutorials in future! Anyone can do it, when you know the right steps! Thanks for the sweet comment.
Thank you. Very informative.
Can you fire this piece and then apply more underglaze and fire it again?
Monica Mathyou yes! I do that often. However I find that the colors do not match after a firing, even if you use the exact same underglaze. Depending on how exact you want your design, it might be wise to recover completely. Good luck!
😊Thanks so much, sweetheart, for sharing your talents.
Thank you, so much, for watching! 😋
Can i apply clear glaze directly to an underglaze painted on bisque ware, and directly fire to cone 6? Or I should separate the underglaze firing from transparent glaze firing?
Also, I would like to ask if I can use sandpaper to sand the bisqueware that was previously underglazed and fired together already?
Fang Xu 👋 you should fire underglaze before applying glaze on top. There are impurities that come out and bubble up the glaze when fired together.
Also, you can totally sand your work! Just be sure to wash the dust off before applying underglaze or glazes. The dust can cause the glaze to detach. Good luck!
@@MissLinneaLark what happen if i alr fired the underglaze, can i still sand the bisque work that alr have underglaze on it?
Fang Xu you can! However it will thin the underglaze and could strip it. But that could make some cool textures!
Was the under glaze used for watercolor also the velvet underglaze?
Yes, however I hate the velvet white so I use the LUG white.
Two questions, please:
1. If I use a colored base (not white as you have done), will the 3 layers of design color be enough to cover the base color? Or will the base color bleed through the design and change the design colors into a muddy mess?
2. Also, I use a beautiful speckled clay-will the speckles come through the underglaze as they would glaze after final firing (^5)? I am hoping so bc I would like my base yellow to appear like spicy mustard when I am done. If not, I will simply use a deeper yellow to begin. My hunch is they will show through....
Thank you! Lovely work!
Great questions!
1. Some colors and brands are harder to get opacity. If your underglaze is really thin I would leave the cap off for a few hours or until it thickens up. That can help cut down on the thinness, which makes it more opaque. I find yellow to usually run thin. Darker colors are harder to cover up than lighter colors, and lighter colors can be more transparent. I would experiment and get a handle on how your colors work with each other.
As far as brands go, I usually like Amacos's Velvet Underglazes. But for whatever reason I have had bad luck with their white not going on solid and opaque. I prefer Amaco's LUG brand for my whites, as I have found it to be less splotchy.
Also, if you start with a color other than white, you will have to careful with which colors you layer on them or you will get a muddy mess. Avoid layering complimentary colors as they usually result in brown or gray when layered or mixed.
2. Underglaze, when applied with 3 regular layers will result in complete opacity. So if you are using quality underglazes you will not be able to see through it. If you just "watercolor" or only apply watered down underglaze you should be able to see the speckles, which sounds lovely. I have never tried. I have also seen people mimic speckles by using a toothbrush to splatter underglaze on top.
I hope this helps and I wish you luck! I would LOVE to see your creations!
Linnea
Miss Linnea Lark thank you for your swift and thoughtful answers!
I usually Sgraffito out the area of the background color I am going to apply a different color to and was considering a short cut since your white did not show through buuuuuut, will play it safe as I have made an entire set of dinnerware FOR MYSELF and don’t want to take any chances! After 20 years of potting, I finally did the thing potters always say they are going to do but never do-full 8 dinner plates, salad plates, small bread plates, soup bowls, cereal bowls, cups, and saucers! AND, don’t plan to gift these pieces, as I somehow always end up doing with my nicest work.
I’ve kept them humidity controlled and wrapped in plastic at leather hard and am about to begin the design portion.
I do mandalas on my work and usually carve the design or outline in a single color raised slip but since these will be for everyday use am foregoing the raised edges to avoid future chips. It will be a while before I am done (an understatement), but will send you pics of the finished pieces.
I found this great speckled Laguna clay I’ve been using for a few years and love it! I haven’t done any underglaze work with it yet, so didn’t know that answer-was hoping to cut out a few test tile steps if you knew that answer, but will experiment accordingly. So, I’ll let you know what happens.
Our kitchen and dining room are both yellow and red combinations so I’ll be doing a yellow background with mostly deep red pattern with some complimentary colors as accents-sort of a take on the old Terre e Provence pieces before they became Souleo and switched to that white clay that washed out all the beauty of the old pieces. Sigh....
I also use Amaco velvet underglaze and expect the shipment of my array of colors tomorrow. Wish me luck and I can’t wait to show you the final product! Thanks for all your help!
Cynthia Rickman WOW!! I cannot wait to see the finished product! Promise to send me a pic of your table set! I love when rooms match in colors. When I toured Monet’s home I was struck by his yellow dining room and blue kitchen and how everything in it matched but still looked elegant. It sounds like your set will be lovely in your dining room and you have a gorgeous design in mind. Thank you so much for sharing!
Thanks for the explanation, the best I have found in UA-cam, and congratulations for the great result! Greetings from Spain
Ah, thanks! So glad you enjoyed it! And greetings from California
What brushes do you like to use with underglaze?
I use Chineese calligraphy brushes because they hold so much. But for small details I use cheap synthetic brushes that you buy in a pack. Sometimes I get paint brushes made for nail art because they are cheap and fine. Hope that helps 💕
Well done and spot on!
Just found your channel and I love it. Thank you!im learning a lot from you. You have a great teaching style too
I’m so glad and you’re so welcome! Thanks for the encouragement 💕
what kind of dryer are you using in between layers? amazing reference, thank you for this!
Monica Mathyou I just use a plain hair dryer. But I don’t let it get too close and I am always careful to keep it moving because if underglazes dry too fast they crack.
So glad you like the video
Very useful tutorial. This has really helped to move me forward.
Thank you so very much! I'm so glad it is a help to you! I would love to see your work!
@@MissLinneaLark Thank you for your interest. I'm only an amateur and have only just started using underglazes so "my work" has some way to go!
@@miwhi2002 This video was actually my first time using a watercolor technique. I saw some pots I loved at Anthropologie and I so I tried to get a watercolor technique going. We all start somewhere! keep it up!
That’s a beautiful unique design
Thank you, Ivy :)
Morning ,
Thanks for sharing this information, love the name!
From Linnea kokinos😎
linnea kokinos haha, always nice to meet another Linnea. I say that, but I’ve never really known another Linnea. I heard someone calling a Linnea in a store once. So nice to know there are more of us out there!
Thanks so much for sharing. This was an excellent video on under glazing!!!
You’re so welcome, I hope it helps 💕
Thanks for a great demonstration and explanation.
you are so very welcome and thank you for the comment! I'm so glad to know you found it useful!
@@MissLinneaLark I am so grateful to you for taking the time to do this for others. One thing I learned that I had not known is, when using underglaze for design, one can apply the matte glaze on top with a brush. Brilliant! I often screw up the work I've done when I try to dip the pot into the glaze ;-(
@@shirleyzussman5823 you are soo welcome! as long as you fire the underglaze before applying clear glaze, you will be golden!
Thank you I been looking for that transparency watercolour very long and everywhere thank you so much
Glad I could help!
What do you use for the clear glaze? Amaco Satin Matt?
Amaco Transparent Matte
What a great video! I learned so much! I will be using your techniques!
I am so glad, Tricia 💕
