Glaze 12.31.25

We couldn’t quite get everything in.

There’s some really nice work here! There’s also a few issues, but not many.

At cone 5, any glaze on the bottom will stick to the kiln shelf, cookie, or stilt. We had to clean bottoms of several pieces before we could even load them in the kiln. Don’t forget to clean ALL glaze from the bottoms of your work before placing it on the shelf to fire.

Pieces that were turned in on stilts, were fired as submitted, but some stuck to the stilts. For best results- always use a damp sponge to thoroughly remove all glaze from the bottom of your work before submitting for firing. Stilts are not recommended.

Also, don’t mix dip glaze and brush glaze. A piece where cobalt was dripped on the piece actually jumped (popped) some of the cobalt completely off in the kiln firing. I’m not positive if it was dipped first, but it appears maybe that’s what happened. It popped cobalt blue onto two other people’s work. It also made a mess in the kiln for us to have to clean up. I’m sure it was just an unfortunate accident, but also something we all need to try to learn from.

We can use more kiln cookies if anyone wants to make some! When a cookie gets too much glaze on it, or gets broken from a stuck piece being popped off, it has to be trashed. Especially if your glaze piece sticks to a cookie, it would be nice if you make a replacement cookie, let it dry flat been two wareboards
And after dry, put it on the bisque shelf to donate for studio use.

Hi there. I apologize …I’m one of the beginners who had a mishap. I need to replace a cookie and a stilt. I thought we fired at cone 6 not 5. I’ve never made cookies can you use any clay for it ?

It’s okay- you aren’t required to make a replacement - just nice when people do. Any clay that can fire cone 5 or above will work. For cookies- cone 5-10 works as they don’t need vitrified.

Cone 5 is actually cooler than cone 6. (Note cone 05 and cone 06 are low fire and NOT compatible with cone 5 mid-fire that we for at)

It’s best to wipe the bottoms off pieces completely clean of all glaze plus leave 1/8-1/4 inch at the bottom of each piece free of glaze too to allow for the glaze expansion in the kiln.

Sometimes stilts work but often the pieces still stick or warp on a stilt when fired at cone 5.

(Just to note- When you see bottoms glazed at the places you go to to just glaze premade pieces, that is low fire clay and low fire glazes- it’s a different type pottery than what we do at makeict. Low fire clay in our kiln firing here would completely melt and ruin the kiln furniture and possible the kiln. )
