Hi Jennie, There are lots of
There are lots of excellent techniques for using float in a kiln (which is absolutely safe) – but they are generally different from the types of things people do with System 96/Uro/Bullseye. Firing temperatures (and schedules in general) usually run about 100 degrees F higher with float tha “fusible” glass. It also has a much higher tendency to devitrify – so consider an overspray (like Super Spray).
Slumping, kiln-carving, and using enamels all work well with float.
You can remove the temper from glass heating and re-annealing it.
