Firing Schedules for Basic Bottle Glass Fusing

I used two firing schedules. I used a slump schedule. And a slump schedule is hot enough to take a bottle from this to this. So that is, it’s hard enough to bend the glass based on gravity and heat.
It’s going to get a little, a little squishy and gravity is going to pull it flat,
But not hot enough to go all the way flat. So let me show you, this is a fuse schedule and this is the other one I use frequently. Okay. So that same bottle, that’s the difference between a slump and a fuse. And interestingly enough, that is only 150 degrees difference. So a lot of stuff is happening in that 150 degrees.
