Bullseye Shelf Primer is tested to 1600º F. That is higher than most people would fire our glass. If you do use it at that high of a temperature, it may have a tendency to stick on opalescent styles. We don't have a problem with it sticking to our slumping molds--it seems pretty easy to buff off with a scrubby.
It might be worth a try. I have not heard of shelf primer "boiling".
Thanks for posting!
