Could you show us how you restore the kiln shelf after something sticks to it? And how did you fire upside down without the top sticking to the shelf?
Stilts, stick a shelf holder with a stilt on-top inside a mug
Love the outro of throwing pots! I could watch those all day
Sir I have been watching youtube for 14 years. This is the first channel that excited me. Not this video particularly, the channel as a whole. Thank you.
This is peter McKinnon but a potter version 😂😂 i love it
Hey Jon, I put my in the oven at 170 F degrees for about 15 minutes and then reglaze , takes longer put I have had pretty good luck. Hmm firing up side down sound and looks interesting, will have to try it. Thanks for your videos.
One note, when using a heat gun to warm the pieces, before reglazing. As the wares are vitrified, they don't respond well to thermal shock. So they heating should be done gradually, and the heat gun moved around, as to not focus the heat in one spot.
I like the look of the mug you fired upside down, in regards to thr flowing glaze look. I don't think I'd like the drips on the rim though. It would be awkward for me to drink from. Plus with firing upside down, you have to deal with either having a bare rim, or getting rid of stilt marks, on the inside.
A little kiln wash with alumina hydrate on the cookies will allow them to release way easier.
Also, I'd definitely wear leather gloves when dealing with jagged glaze bits. Those edges are like a scalpel!
Love your videos!! I’m starting a home studio after 5 years of not throwing I’m super excited! I’m learning a lot from your videos, your origin story is great and you do awesome work!! If you have any tips for someone just starting I’m all ears!!
You are full of talent. It is wonderful. We support you in the future. 🌈🌈🌈
Thanks for pointers on reglazing. Very helpful for beginner learning to glaze. It can be mysterious.
I put my mugs in the microwave for a few minutes before reglazing. Works great!
You answered my question about the cookies on the bottom.
Thank you for showing how to reglaze. That covered a bunch of questions.
Get yourself a set of cheap wood chisels for knocking drifts off before you grind them they're great for cleaning shells as well a lot of times you hold it at less than a 45 degree angle a little tap with a hammer and many many times it'll pop the little drip right off the shelf
I did not see that John answered the question "how do you fire them upsidedown" If you use kiln furniture as I have done it leaves imperfections where the metal rod touched the cup. How do you get around that?
I've officially watched all of your videos! Amazing and inspiring
The Minnesota one was AWESOME!!
Hi there! Thanks for all the helpful videos, they are amazing!! Not enough people show when things don’t work out…I was looking if you ever tried to re fire your kiln load that had not turned out because of an over firing during the bisque fire. I had the same unfortunate thing happen and I am crushed! Did you attempt to deglaze that load? Thanks in advance for your time :)
Thanks for the advice! I have some colours that did not come out well so I’m going to try and reglaze!
I love those upside down drips! Super rad!
Thanks for the great video! Your mugs came out great. Quick question though. What do you rest your mug on when you fire it upside down? Wouldn't it stick to the shelf?
Haha just read the other comments, we're all wondering the same thing
He uses a kiln post with a kiln stilt on top of it and places them inside the mug. I don’t know how he doesn’t get pin marks on the inside though.
I always cast aside by fails... Not now! I will definitely try this technique.👍
Thanks for sharing your tips.
♥️🇨🇦
Thank you for all of your videos they are so helpful!!
love it when you make a sound like 2:47 and 6:31
been on my mind all day long lmao
Thank you for this video. I thought I lost a few pieces. Thank you again. You’re awesome.
Hey the pottery cookies are a great idea! 😄 It could be used over and over again then I'm assuming! Underglaze would never stick to a kiln shelf in a bisque fire right?
I do like the upside down drip
What did you put the piece on when you glazed upside down?
I am curious as well.
our class uses stilts which are like metal pieces that come out of a base and u set the piece on the metal part and it pops off after firing
Me too , wanna know....pretty pretty please
I’d like to know as well.
Me too! :)
How did you stilt the upside down mug without harming the lip?
You do this exactly like I do but I typically use a torch a map torch. I was using my heat gun but the coil went in it I fixed the coil but it's a tenuous fix so I just use the heat gun when I absolutely have to until I fix it properly or buy a new one. But this is exactly how I reglaze things
Could you describe a 'map torch', do you think? What I understand by it (in British) wouldn't get nearly hot enough.
See ya next year Jon...Merry Christmas and Happy New year to you and your family.
Did Jon reply to the question as to how you support the mug when you fire it upside down? I could not see a reply - sorry if I missed it Jon. Love your videos - they are very helpful.
I have had lots of good and many bad regulates. Works great if not on a vertical surface. I preheat in microwave.
Awesome, I have been doing a lot of multiple firing nd never reheat, but I will try. Also your clay body is designed to be fired to a certain temp so multiple firings or more heat work are the best for practical things but maybe that’s being picky. Too many firings, ie. 3x at^6, and giant bubbles will appear, I mean like 2 or 3 inch half spheres. It’s kind of surprising. So now I follow someone’s rule of firing first to cone 6, then cone 4, then a low fire glaze application and fire to cone 04.
Do you know by any chance if it possible to reglaze with a low fire glaze if the initial glazing was done with a high fire glaze?
you are so entertaining 😹
thank you ❣️
Do you refire at the same cone as the first glaze firing?
I had a glaze fire shut off mid fire so it did not get to temp. Can I refire them? There looks like a lot of crawling accured and I'm not sure why. I will now try out your advice on heating up mugs and adding glaze in hopes the glaze all melds together. ugh and ingers crossed!! Thank you so much!
Great video! Do you refire at the same cone as the 1st firing? ☺️
"I should be wearing eye protection." Lol
This will change everything about re-glazing. Aqua Net hair spray. Old fashion hair spray. I spray and let dry at least an hour. Day before is best. I then glaze and sit on my woodstove maybe a minute. Did a kiln firing with 70% reqlaze. All came out great. Turned otherwise bonifide rejects into beautiful pots
Thanks so much we Need this video appreciate you 👊
I've been using thick glaze with "seroil" (don't know if it has a different name in English, the fixative to decorate in 3rd firing) and just paint it on the problem spots, works great! but with bigger pieces sometimes the parts that have not been repainted come out of the refiring a bit bubbly - lots of tiny tiny holes, probably because of the re-melting. does heating the pot up before reglazing get rid of this problem? thanks! and your videos are great!!!
Am I really first?
You are a great potter!
Thank you for all your "classes"
INTO . SKETCH yes your are good job!
WOW! what a great video! Do you refire at the same cone as the first glaze firing? I really need to try this. Hope you can help 🙏
Hello, how you do to refired a piece upside down
What did you use to hold your piece?, thanks
How did you fire it upside down? Wouldn't the glaze on the inside stick to what ever you used to prop it up??
I think it gets balanced on a long Metal spike, right in the center of the inside of the cup.. Like those spikes for cash slips, but with clay bottom not wood Haha. Should be easy to make yourself.
Just not sure what metal works best with the heat- you have to experiment with it to find out.
it wasn't fired upside down, the shelf above was too low
@@thesouthwestern You really have to buy metal wear from a pottery supplier. Most metals melt a whole lot lower temp. than cone 6!! I use a lot of stilts for my 0.5 earthenware which are always glazed on the bottom. But for my cone 6 stuff I've never even heard of metal stilts. You can buy porcelain stilts which like Jon's cookies lift the stoneware off the shelf - only on little nubs. The porcelain won't stick because it's already vitrified at cone 10 but it would certainly stick to glaze so..... I'd love to know how he fires at cone 6 upside down.
@@Middlesex1957 I will have to do some experiments of my own hehe.
@@naplin I think the mug referred to here is the one with pinholes from the first firing (8:05) that was refired upside down, not the one that touched the shelf above in its first firing (0:35).
thank you, good tips!
Beautiful blue color. May I ask the glaze info?
How did you glaze upsidedown?
This is awesome! Could you do a video about better glazing techniques? I always get pinholes and super thick dripping (even though I dip it for 1-2 seconds).
Pin holes can be a lot of things. You can try bisquing at a higher temp, say 04 instead of 06. A short (5-10min) hold at top glaze temp can help. I use a dark clay prone to pinholing, so I have a 10 min soak at top temp then drop 100F and hold again for 30 minutes to let bubbles heal over.
Thick glaze, you may just need to add a little bit of water to your glaze to thin it out more.
Try firing your bisque at a higher temperature, then your pot won't be so absorbent and take up less glaze.
Question? Can you heat the mug quickly in a microwave to speed up the process of heating it? Thx for the tip on the little pieces that you sit your mugs on.
This is what I do - microwave is great! I do it in little 5 second bursts. Also good for raw clay pieces but you have to be super careful not to over do it.
@@JamesHayesArtist Thanks for the info, I have some reglazing to get done. So I'm going to give it a try.
What glaze did you use on these mugs, I love it so much. Thank you.
It's that one for pens or tools
Newbie question - how do you fire upside down?
You use a peice of kiln furniture called stilts and put them on the inside with them upside down then fire them and voila you have fired a peice upside down
How to make pinging in pottery.please post a video
Why can’t you paint on the glaze to just the parts you want regraded instead of dipping?
Dipping will give a smoother coat, and (l thought of asking about this) the edge of the overlap doesn't seem to show after firing.
I set my kiln to 200 with 10 hour hold. Throwing things in trash can be thrilling!
You know what's cool about handmade items? they never turn out the exact same and they sometimes come with human imperfections. That's what i love about handmade anything! paintings, pottery, crochet... it's all so unique and imperfect. Much like humans if everything was a cookie cutter version of the thing next to it, we would live a very boring and mundane life.
Merry Xmas John
What was the firing temperature after reglazing?!
when you fire them upside down, how do you prevent the drips from sticking?
cool
What kiln do you have? And would you buy it again? Would you buy a better kiln?
Jon, how do you refine upside down without having the already glazed surface stick or be damaged.
When you make your cookies to place your mugs on, looks as if you make the diameter of the cookie smaller than the mug base... so if it drips it won't stick to the cookie..did I get that right? 🤔 kisses to the boyz💋
I tried to refire two big slabmade baking dishes, both got big cracks when refired the second time.. Any ideas of why?
Do you fire first glaze fire at cone 6 for your pots? I have had 5 pieces fired at the community studio where I take classes, and all 5 pieces aren't vitrified, and have to be re-fired. They are firing at cone 5. They told me their hold time wasn't long enough. I'm a newbie, and just learning. Wondering if firing at cone 6 first time, will take care of the problem? I just bought a kiln, so excited to handle these problems myself.
I love to learn this..is there is any way that i can learn this?
How do you fire upside down?
Doesn’t the stilt get stuck in the melted glaze when you refire upside down?
Please show us how you fire upside down!
How, exactly do you fire something upside down???
Jon is it possible to order a mug from you? I've been watching your videos and I'm ready to start playing with clay at 68 years old.
does it affect food safety if you reglaze the inside?
Casually looks at watch to check what month it is 😂
What causes pin holes please
yeah, Jon...how the heck do you fire upside down?
How did you fire the mugs upside down?
How do you grind downthe drips but maintain the shiny finish?
I watch this on the television and I wanted to know how he fired a glaze piece upside? I specifically came on here to find that answer and I see that five or six people have answered it and I guess nobody is going to get an answer because the questions are all from a year ago and it's never been answered as far as I can see?

How can you fire a glazed pot upside down?
Hi! What ways are there to scrape off extra glaze that has dripped and accumulated at the bottom? Anyone? Thanks! :)
How did you fire it upside down?
My vase has pin holes after glaze firing. It was then refired and there were more pin holes, is there anything I can do?
Firing to a higher cone and holding the temp can help,provided your glaze and clay can handle it. Unfortunately often it’s time to practice non attachment and make a new one to be honest.
Sometimes glaze develops holes with bare bisque showing, like maybe it bubbles out and pops. Do you know what causes this, and how to prevent it? Sometimes I try filling the holes with glaze, but it pops out again.
Could be dust?
@@maurice1606 what kind of dust would do that?
Don't know, honestly. So probably clay dust in the studio, house dust or anything. My tutor has just told me to keep bisque ware covered, and brush any dust off before glazing because it can cause small flaws.
Also, when you make you're own cookies, are they just bisque fired, when you make them?
I know you asked a month ago but I feel like you deserve an answer. When my professor had us make kiln cookies, we bisque fired, added kiln wash, then fired again. The kiln cookies were just square pieces we reused until they broke or got accidentally glazed or whatever.
“Boop boop boop boop boop.” -JTP
Please - eye protection when popping cookies
Everyone is aching to know how you fired the upside down MN mug. I know you wax the bottoms, but noticed that the glaze stuck to the bottom in the second firing. This mug could be a whole video unto itself!
Hey Jon. do you know what causes pin holes?
Try increasing your bisque soak time, this should burn out the gasses that cause pinholes.
I hate that you have to throw it away, some people like "ugly" or "misfit" things. I wish i could get it lol it would make a cute planter...
Jon, not to be crossing boundaries, but I would NEVER glaze a pot with a drill inside of the bucket. 😭 that’s how you lose fingers and hands 0:26. This is really unsafe studio practice.
You could break up the throw away pots and sell to gardeners for the bottom of plant pots.
I love the comment section xD
Saftey squints
The last video of 2019. *sigh*
My guess is a stilt on a post
A question, when you fire upside down and you get the drips on the rim, how do you support the mug so it doesn’t stick to your shelf?
