I have a kiln fired project that I am ramping up to build.
‘When you have two full fuse firings and a fire polish firing, when do you anneal the piece’
I am firing a detailed three layer casting that varies from 9mm thick to 25mm thick. I am planning to use the annealing thick slab schedule for 50mm thick glass. This schedule is ~47 hours long. I am hoping to get an answer from someone with experience on castings with multiple thicknesses.
I cast a piece a while back with similar technique, using annealing cycle on both full fuse cycles but I used a 25mm slab annealing cycle on my 6-19mm piece. Still got a nice crack. I blame the crack on the rigid inlays, not necessarily the firing cycle.
Castalot mold mix, all bullseye sheet glass and frit (fuse 90coe compatible)
