Title: Two-mould firing schedule
Post by: Burlingham Glass on November 21, 2016, 10:49:15 AM
I've got Creative Ceramics Bowl mould 958.294 and Lamp Bender 958.354. I'd like to fire both at the same time with 6mm thick glass items previously fused. Could I use cycle B3 for them or Cycle B? Or could I use a mid-point top temperature and mid point hold there? I can see that there is a fast ramp up and lower top temperature on the lamp bender but was wondering if a slower ramp up would be so bad for the lamp bender.
Alternatively, would a fast ramp up and a lower top temperature for longer work for the bowl?
I use float glass so have adapted the schedules (that both work perfectly) as follows:
Lamp bender: 400/673°/020/000/555°/040/200/370°/000/200/040°/001
Bowl: 120/538°/025/050/700°/100/000/555°/050/150/370°/000/200/040°/001
I am working to an exhibition date and simply don't have time to do 2 firings.
I'd be most grateful for any advice.
Thank you.

I don't think a slow ramp up is bad for anything.  Becky Wills from Warm Glass always ramps up slower than normal programmes, and her work is lovely.

Thanks Nick, I used the slower ramp up and the higher firing temp and it all worked well.

That's good! Glad to be of help.
