Kiln firing soft glass is ending up cracked between colors after the fusing?
As the title indicates: I'm using soft glass COE 104 Moretti
Fusing schedule:
200/hr to 1250
500/hr to 1450
Hold for about 30 minutes
Full to 1250
200/hr to 950
Hold 1 hour
200/hr to 200
My moulded glass pieces that I slump into the mold do good, then when I take them out to fuse something more and give a better fire polish look with an annealing it is just not working. I'm getting cracks in just about every clear encased item.
How do I do it? Should I adjust the schedule? How many times can 1 piece of glass go through the kiln before it looses it's strength? How does kiln firing glass affect the COE factor?
I respect anyone with the know how to do this kinda stuff and I really appreciate knowledgeable advice. thanks!
