Kiln Schedules

Below are my kiln schedules and their uses for both soft and borosilicate glass. I use a Paragon SC2 with a sentry 2.0 controller and are provided as a rough guide to a starter annealing schedule. The 104COE schedule is also good for 96COE as I will garage and anneal them together.

I set these based on the largest pieces I tend to make, for larger pieces remember you will need to adjust the ramps/times accordingly. The first hold is for garaging and can be nudged onto the next segment when you have finished working.

All temperatures are written as Celsius/Fahrenheit
