Nana,
My first thought was to make subway tiles, but I have yet to make molds. I understand you can use stainless steel for molds & I have some electric range burner covers that are ss. I need to drill a hole first (correct?)...do I need kiln wash in the ss molds too? I thought I'd melt in those & then slump into bowls. A friend told me to she fires to cone 016 to make melted wine bottles, but I can't remember if she said fast or slow...do you have a clue? Also, my kiln is is different from hers in that I have heating elements in the top as well as the sides. I don't know if I adjust the cone for that or not. I know...I should just do it & see what happens...it's not like the glass cost anything. I don't know what's wrong with me, I'm really quite timid when it comes to my kiln.
As far as greenware & glass together goes, my clay bodies fire at 06-08, much higher than for glass. And I know what you mean about the blow ups. In the past I've made some huge multi-dog water bowls by throwing the base, attaching a huge coil, & pulling the sides up on the wheel...comes out really cool especially after adding puppy stamps & the like. Anyway...Colorado = arid = no trouble...Missouri = humid = drying for a month plus = explosion everytime.
