It always happens. I have a 10x16 piece that is 3/4" thick. I wanted to trim it up square before cold working. I guess I got too close to the edge. While cutting, a crack appeared and started across the piece. Can I take it to full fuse and heal the crack, and if so, what type of firing schedule? I tried cutting some scrap 3/4" and if I cut off at least 1/4" I was fine. When I tried to just trim a little, it too cracked. I am using a 10" tile saw with a result blade from HIS Glassworks.
Any help is appreciated.

sure, why not. however, if there's ANY temp diff across the piece, expect that the crack will shoot across the piece on the way up.
at 1480, won't it grow since it's 3/4"? you'll have to dam it to take it to fusing temps.
the firing schedule should be really slow going up to 1000 at least. after that you can use your original schedule for that thickness.
