Using partially cracked glass in layered piece
Posted: Tue Oct 29, 2013 10:31 pm
I'm working on a piece that consists of three layers to be fused before slumping. The pieces are 16" dia. circles, and so there's a fair amount of glass involved.
One of the layers is BE 1122 (xparent red), one Tekta, and the third 4113 (clear with white confetti and clear stringers). While I was running the circle score in the red glass it cracked, but only about halfway across - and hence the piece never separated into two pieces.
So my questions are:
1. What are the odds the crack will be visible after fusing?
2. If a positive outcome to fusing is iffy, would I be better off cutting a new piece and using the cracked one for smaller projects? Or rolling the dice?
3. I have a little flexibility as to whether the red layer will be sandwiched, placed against the kiln shelf, or fused as the top layer. If I were to persevere with using the cracked piece, would one position be more likely to minimize the probability the crack showing?
Thanks, all.
