I anneal at 1050f for 1 hour, cool 200f/hr to 850f, then 300f/hr to 600f, turn off kiln. Been doing it this way for many years seems to work well. A piece did break yesterday though, but that might be due to it being dropped from
about 3 1/2 feet onto a concrete floor. Not testing just butter fingers.

This is the schedule I use for pipes. They are at their thickest at 1/4". Don't use this for thicker glass
