What glazes are used on this?
Is there any chance these glazes are going to run that are layered on this piece? With the layering all the way to the base, I’m afraid the glazes may run off this onto our kiln shelf.
Unless these are both celadons are are known to not run when layered, this piece can’t be fired with the layers so close to the bottom.
I suggest you maybe make a large flat “cookie” for it that’s big enough to fit under all this and catch any glaze runs. We don’t have any large enough for this piece.
I used Smokey Merlot and river rock (dots). I did only one coat of the dots, I’ve only had it run a couple of times but that’s when I’ve done 2-3 layers of river rock. I’ll come in some point to clean the edges more. If I wipe away the glaze on the foot would I still have to make a larger cookie?
Thank you for the info. Please wipe it back to leave 1/4 inch minimum bare with these layers.
River rock can make some glazes run a lot but a single layer on Smokey merlot shouldn’t run much from what I can find about it. But they aren’t necessarily not going to move at all.
Please always be cautious with layers, especially on the bottom 1/3. If its layers known to you to be stable together, please leave a note with your piece letting is know what it is and that the layers are tried and true.
It’s a pretty bowl.
Sounds good! I thought it was 1/8in rule but 1/4 inch makes wayyyy more sense lol. I’ll take care of it and I’ll leave a note when I’m not able to use a cookie!
If I wanted to make large cookies for future projects. Could I use reclaim clay or use b-mix so there’s no speckles? And what’s the prep process for cookies, is it just bisque fired then coated with kiln wash?
Reclaim hasn’t worked well for cookies because it tends to bloat after a few firings. Bmix works well and holds up much longer. I use a cone 10 clay for cookies because it tends to last through even more firings. (I don’t use cone 10 for anything else and never add any cone 10 to the reclaim)
But yes reusable cookies are just clay slabs rolled to about 1/4 inch, dried between two ware boards to stay flat. Then Bisque fired. Then add 3 THIN coats of kiln wash- ideally with overnight dry between coats.
When cookies end up too coated with glaze to reuse, or break too small or bloat too much they end up discarded.
Keeping glaze off our kiln shelves is very important. It’s a ton of work to clean shelves and keep them in good shape for use.
Note- please carve name in the bottom of cookies if you make your own, otherwise when we unload the kiln we confuse them with makeict cookies.
The Makeict cookies are all made by members and donated for community use so there are a variety of types of clay that have been used For them.
1/8 inch for one color stable glazes to give room for expansion when firing. . 1/4 inch minimum for any layers.
For layers that run- sometimes much more bare clay at base is needed.
It’s not a one answer for all situations unfortunately-
We wiped this back enough to fire it we think and it is currently in the kiln firing tonight.
I appreciate it! I haven’t had time to come in this week to take care of it I’m sorry! I think a rejection shelf should be made so you guys don’t always have to clean up peoples pieces. I’d be happy to help set up a shelf or reorganize to make space for one.
We’ve been giving some thought to where we could maybe set one up. That’s going to be the best way for people to learn what they need to do or not do for successful firing of their work.
