fixing a crack on a tack fused/ slumped piece
Posted: Sun Sep 30, 2018 9:23 am
I have a piece that cracked on cool down slump. The crack edges are sharp but only cracked halfway down.
The piece is 13x6" 2 layers of clear with bubble powder and powder frit in between full fused. Decorations and frit tack fused on top. It was then slumped on a large stainless steel s-curve. It is pretty thick in spots where the decorations are and crack between 2 heavier areas on the top of the s-curve.
If I slump it flat again I can add some stringers or frit over the crack and take it back up to a tack fuse and the slump again.
Is there a way to repair it that I haven't thought of?
If I slump flat will there be any issues with the glass moving?
BTW I'm pretty sure it was a thermal shock problem. I peaked in at what I thought was 100 F but later realized it was still at 180F. Glasses would have helped (DUH)
TIA
