A piece I fused developed a crack while cold working (guess I got a little rough!). You can not see the crack, but you can feel it. The piece is 1/2" thick. I'd like some suggestions on a firing schedule to heal the crack. I will re-dam the glass prior to firing. How far up should I go? Do I have to go to a full fuse or can I get away with a lower temp? Many thanks in advance folks!

You'll have to go back to a full fuse. Brock
My memory is so good, I can't remember the last time I forgot something . . .

and heat it slower, as it'll thermal shock easier and the crack may propagate further. damhikt.

Did exactly that and the crack healed nicely. This is one piece that is NOT destine to be frit!
