Has anyone ever just fired glaze? Like, if i took paper and glazed it with enough layers until it got thick, then fired it. It randomly popped into my head.

I'd be inclined to let it randomly pop out again, what's the point?


How do you propose preventing it from sticking to your kiln shelf when the paper burns away?

It would take a lot of experimenting but you could use glass molds. I'm no expert on this but I think the main two ways glass is worked other than blowing is slumping and pouring. You'd be doing sort of a cross between the two. You wouldn't be potting anymore, you'd be working with glass.

This CAD article talks about firing glaze w/o clay.

Good post. When you get a chance check out "Wood Fire Clay Body" thread. I asked you a question there.

Awesome....really just trying to find a way to glaze 100% of my product, and asking in a sneaky way. Anyone know if i could make the bottoms of my product with (glass over clay) to give it a clear glaze look. Wish I majored in chemistry in college now! Thanks for the responses....much appreciated.

Sure, you could fire them upside down and slump some glass on the bottoms being careful not to fire high enough to soften the glaze, but it would probably look awful. Maybe, instead, use a low-fire glaze on the bottoms. Again, obviously, the glaze would have to melt at a temp too low to soften the other glaze. I don't know what you're firing but another option might be to fire the piece on stilts so that the entire piece is glazed with only a few scars where the stilts were, which can be sanded down to where they are almost invisible or even use the second option above to glaze over the scars.

Just brush glaze onto the base of your piece and fire it on stilts.

Yeah, I can't use stilts for what i do. Is it possible to make a glass shelf and put it on my kiln shelf, and then glaze 100% of my piece and set it on the glass without it sticking? I almost want to go back to school and study chemistry to solve this problem. There must be a way to make a shelf that wont fuse with glaze. I spent an hour one night researching melting temperatures of metals.....but i dont know enough about things in general to make any educated guesses on the matter.

Not sure if you can get the temps you are looking for but you could try Bullseye kiln paper. It only goes to 1600F and is used normally for fusing glass. T

I suppose you could fire just glaze, an epk/alumina wadding mix should provide a decently removable skin you can remove with a little buffing ... it won't be really all that appealing since it's not really forming glass so it can easily shatter on you and it won't be glossy where you basically made an alumina mold ... but it would work to some degree.
