Fusing old stained glass

[olive dabeach]

I am starting some little fusing projects using small ring bead molds and old stained glass which I don’t know the COE. I have tried the recommended schedule for the mold but it didn’t melt it all the way  tried it a second time a little hotter and no change  any recommendations for a schedule that I could try?

You have to totally fuse the glass in the mold; so, you have to reach the fusing T* of the glass.  Using a total fusing schedule, you have to increase the fusing T* up to the required level.

I go with increasing 20*F by try.

you need to observe the glas, as you don’t know the fusing temperature. You may also be experiencing some devitrification
