I'm a potter and old school craft enthusiast in Denver, Colorado. I'm enthusiastic about creating things that are of quality and unique - things that have personality in the age of plastic and mass production. I would like to share what I do with those who are interested, and learn as much as I can from those who share their knowledge as well.
15 minutes of jiggering and stamping. Production Pottery process.
The jiggering and stamping process for trinket dishes. These get a stamp in the inside center, in this case a bison, which is mounted in the jig that fits over the mold. The stamp is lightly oiled after each impression to keep it from sticking to the very wet clay. The clay used is quite soft - softer than used for throwing, to ease the process and make sure the clay fully fills the foot ring in the mold. The dishes shrink and release from the mold within a few hours and the molds can be re-used several times in one day. The jigger is laser- cut from 1/4" abrasion resistant steel, the edge of which has been ground and polished to a bevel to help smooth and compress the clay into the mold.

Soda Kiln - First Firing Review.
Переглядів 2673 роки тому
I've always enjoyed soda firing, so I finally got around to converting my kiln so I can do it in my own studio. I unloaded the kiln today and this video is a critique of the results. Getting to know the kiln is going to take me a while, the firing characteristics are quite different after adding the lining material, and I'm not a very experienced soda firer to begin with. Despite the second she...

Reduction Luster Firing
Переглядів 4994 роки тому
This week, I've been experimenting with clay paste reduction luster pigments. The recipe I developed is based in an educated guess as to what the proportions if the ingredients should be. I used 1part silver carbonate, 1part yellow ochre, and 1 part calcined kaolin by weight. Based on my limited tests, I think increasing the concentration of silver carbonate in the recipe would lead to a better...

This video is a compilation of snapshots taken throughout the course of an 8 hour reduction glaze firing. I fire my ware to cone 10, which is approximately 2374 degrees Fahrenheit at this firing speed. The approximate firing schedule is as follows: I slowly raise the kiln's temperature and hold around 200 degrees for half an hour. I then raise the temperature to 300 over the next hour. Over the...
How to Fire a Pottery Bisque Firing in a Gas Kiln
Переглядів 6 тис.4 роки тому
This video discusses the process of bisque firing stoneware. I don't keep a firing schedule for bisque firings but here's an approximation. All the work I fired in this kiln was bone dry. In programmable kilns it is possible to dry work out by holding the kiln at a low temperature for a long time ( this is called candling), but I choose to only fire dry work. Candling for long periods in a non-...

Testing materials for fire brick making
What the heck is Wilco Kaylin???? The transcripts shows you said "Will Cocaine" ... You say that quickly like everyone is supposed to know what that is.... I still haven't found it on google????????????///
Seems like the single largest constituent of the white ash from my wood burning stove is calcium carbonate regardless of what type of wood I burn. Well below that, in second place is potassium carbonate. The rest is so low I don't think much about it.
What trimmer are you using? DIY?
It is a homemade tool - I make these out of metal pallet pack banding. I try to find the very thick stuff, which is actually made from medium carbon steel, so it can be heat-treated to hold an edge after bending and grinding. I find it makes very good tools.
I am impressed how much material it smoothly removes! But you have the skills that make it look easier than it is. Great video - fun to watch. And thanks for the comment response, as I was running out of internet search ideas to find the trimmer online.
@@HuddyMcQueen Thanks! if you decide to give it a go and make one for yourself, beware that it can chatter pretty severely because of how springy it is... you'll notice I hold it =quite tightly and closely to where the tool is touching the clay to help dampen the vibration. Happy Potting!
Thanks for the advice. Yes, it seems like a fun project & with a great tool as a reward at the end. I’ll let you know how it goes when I get there.
Thanks for the good bisque firing info.
I've got a gas kiln I made out of an old clothes dryer drum with ceramic fiber insulation and a single weed burner that I use for both bisque and glaze. I was seeing substantial soot if I candled with the gas, so switched to drying my pieces in an electric oven at 190F for an hour or so while I'm setting up the kiln. My firing schedule is way more aggressive with cone 05 in about 60 minutes. Once the cone falls I pull out the weed burner plug up the chimney and fire hole and let it all cool for about 8 hours before venting the lid for another hour to get rid of the last of the heat. I'm firing wild clay that's been spiked with ample mullite and kyanite for raku so it seems to not mind the accelerated ramp up to 1900F. I use BBQ propane tanks which are about $20 USD to refill and get 3 or 4 firings out of each one, so $5-$7 per firing. For raku, it's the same except I pop the kiln at 05 and set stuff on fire with the glowing pots.
That sounds like a neat process! I'm happy that you have found something that works so well for you. I love wild clays and I have found them to be more resilient in so many ways when compared to commercial clays. the dry strength is often crazy good. there is a clay that is local to me that is so strong when dry, that I can stand on a greenware flowerpot turned upside down without it cracking! happy potting!
Great presentation 🙏
Thank you for posting this! It gives me hope with big hopes and dreams 🫀🫀🫀
Did you ever build the kiln? We have been trying to find cheep used firebrick and I think this is a better way to go.
I am actually still working on it and working on various recipes. i have one in the works right now that is promising. 1/3 kaolin 1/3 cone 10 stoneware reclaim, 1/3 sawdust. it's still in testing, but it is showing promise so far. I did build a kiln, but I ended up coming by some bricks to use that were less labor intensive. Good luck with your kiln! I might make an update if this recipe works out.
@@liamg1995Hi, if you wouldn't mind, what recipe worked best in the end?
Um verdadeiro autodidata. Parabéns!!!
What type of brick is this?
Tijolo refratário, também pode utilizar manta cerâmica 50mm, 128kg/m3 para até 1400 graus Celsius, um pouco mais caro mas, com resultado rápido e fantástico. Fiz um forno para Raku usando um tambor de 200L. Abraço!
It's coal!!! It's not ash. Ash is whiter

Qual o nome desse massarico
Enjoyed your video! I am experimenting with grass ash from a very salty environment. I would like to make a black and white glaze in reduction for an art piece. The hard part is I have to keep top temperature bellow 1600 f . And I only want to use local clays. If you have any tips for me it would be greatly appreciated !
Why not a pyrometer for bisque firing ? I would think that’s when you have to monitor the temperature change more closely ? Great video.
There is certainly nothing wrong with using a pyrometer! I just don't find them necessary. After a while you get to judge temperature fairly accurately by eye and your senses, and only rely on the cone for the indication of the final temperature. Happy bisquing!
how did you fire the homemade bricks for your wood kiln?
Good video. Can you estimate the cost for a firing? I'm trying to work out whether to get a gas or electric kiln. Thank you :o)
Hi Wendy! I estimate that a firing to cone 10 in this kiln costs between 10 and 20 dollars depending on the price of propane. A bisque is a big less. A 100 lb tank costs about $65 to fill here these days. I also have a downdraft kiln that is slightly more efficient.
@@liamg1995 Thank you :o)
Notiihuig
Thank you! What are the 3 elements? My english is poor... Ashes, sodic feldespat and....?
Hi! The three ingredients are hay ash, soda feldspar (minspar brand) and kaolin (tile #6). The hay ash has a high flux content. It is likely that sodium (Na) and potassium (K) compounds make up the majority of the fluxes in the ash. It also contains silica (SiO2). The feldspar also contains silica and sodium, and probably some alumina (Al2O3) as well. It is primarily used for the sodium and the silica though. The kaolin has a high alumina content and acts as a stabilizer for the glaze. Together, these three ingredients in the right proportions satisfy the criteria for a good glaze, which needs a flux of some kind (in this case sodium and Potassium), a glass former (almost always silica) and a source of alumina as a stabilizer (almost always from clay). Hope this helps!
@@liamg1995 What you are doing is great, good luck, please I have soil of different colors, what materials are added to the soil, so that the paints of the color become primitive pottery,
@@sandgrains3418 hello! I am afraid I do not understand your question, could you please rephrase it? Happy, to help, I'm just not sure what you are asking.
😂 😂 😂 I also don't remember what I wrote, because I don't know English and use translation, but I was looking for how to make a paint of ash, please add automatic translation, I answered you to reflect your beautiful taste, my greetings to you 🌹
Thanks - going to try this. Did you video the finishing steps (trim/glaze)?
Thank you very much for this video. I was wondering how long does it take to reach cone 10 in your gas kiln from cone 08 where you started reduction? Do you leave it in mild reduction all the way to cone 10 from cone 08? Thank you very much indeed.
TOP!🇧🇷
Great research, thank you so much, I love your process! It would be fantastic if you add in the description or in the comments the list of matereals, so It Would be easier to translate, Greetings from Italy🔥
I've watched so many videos of people trying to make fire bricks or refractory mixes but this is the first one that seems to get it right. Others always have some issue: either they use cement in large proportions and ruin the refractoriness or use expensive materials like castable refractory and perlite, which defeats the purpose of DIY. Thank you for doing the leg work to figure this out! What are you using as a mortar between the bricks?
Wow! 15 minutes to make 1/4 of a brick. That ought to take you about 12 years to finish your kiln. And no update video? Congratulations. You succeeded in wasting every viewers time.
Man, it must be a real bummer to see everything so negatively! Firstly, these were experiments. Your comments on efficiency are kinda pointless. It would be ludicrous to process several tons of material by smashing it with a cinder block or similar method. You and I both know that. I would have had to build a pan mill/ hammer mill or something. Secondly, the reason there was no update video is because I didn't end up pursuing this material any further. The brick factory I got it from decided they could no longer supply me with the quantity I needed. I would have had to order a whole truck load (40 tons) to make it worth it for them. I need roughly 3 tons. The bar made of the mixture of the two materials actually made a satisfactory fire brick material. The extremely refractory stuff alone didn't even fuse and remained crumbly at cone 10. It was a bummer really, because it was good stuff. Sometimes projects must get abandoned though. After I figured out I wouldn't be able to get any more I just moved on to other tests and materials.
@@liamg1995 FYI, I don't see everything negatively. Only the entire content of this video. Being that you decided to NOT do a follow up, after saying you WOULD, you should have put a disclaimer at the beginning of your video, saying that in the end, you decided not to pursue the final results, due to the amount you'd have to process, or the materials used were not available or that effective. But, in the end it's your video, so you can post it any way you want. You just have to accept that ppl will leave comments like mine when they are looking for information and realize they just wasted their time on something that was completely pointless. However, if you don't want constructive criticism (sometimes brutal, as they may be), you can choose to disable comment completely.
@@F5Tornado44 I'm not really interested in arguing with you here in the comments section. Here's what I've got to say: You're not wrong in pointing out that I didn't follow up.... That, I'll give you. Generally though, when you give people "constructive criticism", the idea is to maintain their receptivity. That usually means not being unnecessarily nasty or rude. In that aspect, you weren't particularly successful. That's kinda why I got a little defensive in my previous comment. You could have just politely asked for an update, or whether I was still planning on uploading a follow-up video. I would have been much more willing to share my results, and maybe even chat with you about your project, if you're working on one at the moment. Ceramics is just as much about community and the relationships potters forge with each other, as it is about clay and the making of pots. There's no room for animosity in this community as far as I'm concerned. I make these videos for fun, and I share what I do because I love this craft and this material deeply, and I think my projects might be interesting or constructive in some way for those who *choose* to watch. I'm always learning, and really just documenting my own experiments. When they don't pan out, I ditch them just like I do pots that don't work out. I have other stuff to do. Please understand that I don't do pottery for the purpose of making content for youtube, but rather, I document some of what I am working on as a potter on youtube. If you ask a friend to borrow their notes to study for a test, do you then complain to them that the problems in them were incomplete or that they missed a day of notes? I sure hope not! Sounds like a good way to lose a friend.... Heck, if they get you half way there, or even give you some interesting ideas to work with, that's more info than you had before... How about this: I'll show the outcomes of the tests in the next video I do. I wish you happy potting, I hope you find peace and fulfillment in this wonderful craft and material. Clay truly is the gift that keeps on giving.....
say "wear gloves" then puts bare hand i to the mixture, exactly my way of doing :) what range of temps are you fairing them up to?
Hello! I fire these glazes up to cone 10. Thats roughly 2375 Fahrenheit or 1350C
@@liamg1995 Can this be fired cone 9?
@@liamg1995 What about a really low temp glaze? I'd like to have something that I can fire in my wood burning stove. I've been making beads and such from my local soil (levitated and filtered) and firing them in oak coals. I've been looking for a way to do some sort of low temp glaze with materials directly from my property. I have egg shells... So I have ashes, clay, I can make whiting. Oh! And I can make bone ash. It seems like I would be able to come up with something that will melt at a wood fire temp.
man do I ever envy you having enough spare time and ambition to be able to look at this level of detail. Great process. Thanks for the inspiration
A tip : you can watch movies on Flixzone. Me and my gf have been using it for watching all kinds of movies lately.

@Oscar Angelo yea, been watching on flixzone for since november myself =)
thank you so much for putting this together. I've got a 50lb bag of fire clay, coincidentally some guy emailed me today asking about fire bricks and this just popped up as a suggested video on youtube. I only watched 2 minutes of this but I'll save the rest for after supper.
Good chat, and demo.
Enjoyed the review. When yo re-fire the crawling will you aim for higher temperature area in the kiln? Ta for sharing.
Hi Freddie! I think I will refire the pots that crawled right next to the burners for the best chance of them coming out. I'll also add a little whiting to that glaze (maybe 2% or so) to help it melt. I'll share the results when they're out!
Ta for sharing!
Thanks for watching!
I like how you use your hand thermometer......hope it holds up well. Thanks for sharing!
nice video, liam. and timely since i have een playing with plates of different shapes and sizes. great tips, skip
Thanks Skip! Best of luck with your plates!
liam, would you use the same technique on a platter?
@@georgenoe154 Yeah! I would do a platter the same way, but because the bottoms are thick, the amount of clay used goes up exponentially as platter size increases. For a 12" plate I'd probably use 4-4.5 lbs and for a 16" platter I might use 8 lbs, for a 24" I might use a whole bag.
das ist cool … ich mag es deine Stimme zu hören!!
