Firing Schedule for Precuts
Temp probes never match from kiln to kiln. For instance, these are the two firing schedules I use to achieve a TAC fuse. I recommend starting with Jen-Ken settings. Always do a test firing with scrap glass before using your precut. If the edges do not adhere all the way around the precut, bump up the 1355 by 10°. If the piece appears to blob and distort (not maintaining the precut shape) lower by 10°. ***These temps are both much higher than standard Tac fusing temps but have worked well for me.
