Fusing bottles mystery

[sandie]

Debra thank you so much for the time you have taken on this subject.  I actually have tried fusing on paper as well as directly on the shelf with basically the same results. I haven’t gotten a chance to try it while I do a screen melt so I don’t know if the bottle glass needs to fire that high for that long in order to get it to respond. This is just so frustrating be cause I see the rIngs in a lot of places but I can’t get anyone to share the firing schedule.
