Hi Wendy, in my Fuse It book
in my Fuse It book I have a chapter “Recycle It” – were you will find some things to do with bottle glass. I ususally fire bottles with my other full fuse firings and never had a problem.
The firing schedule I’ve been using in the past 10 years is
ramp up 10/min – 600 per hour to 1000 hold for 10 min
ramp fast to 1450 – hold for 10 min
ramp down fast to 960 and hold for 1 hr
