kilncarving

[The Hobbyist]

Switch from 1/8" fp to 1/16" fp and it will work well.

I teach kilncarving in my basic class & let the students go 3 to 5 layers high with fiber paper, using 2 layers of 3mm. We don't prefire to fuse first, just design, cut & stack the fp, place glass atop & fire. As Rosanna said, the firing schedule would be helpful, but without it I'd guess firing too fast; &/or could there have been too much glue under that high point that may have caused excess air?

the glue has outgassed well before the glass moves . rosanna
