Multiple high hest firings
Does anyone know if firing multiple times (5-7) at 1600 and higher makes the glass unstable?

Re: Multiple high temperature firings
It does.
I'd be leery of firing more than once (and twice at the most) at temperatures above 1600F/870C. Incompatibility can result. It's especially likely with whites, with glasses containing aventurine, with glasses containing gold, and with pieces you absolutely don't want it to happen.

Re: Multiple high hest firings
When Bullseye first started there were some colours that you could fuse but try a second firing and it would break.
Now the description I believe is 3 full fuse firings.
Since fuse firings are nowhere near those temperatures you are way over any chances of stability.
I only fire glass twice for that reason.
