Slow vs Fast
I have an Olympic 2827 with Controller. The controller has 4
preprogrammed firing schedules---slow/fast bisque, slow/fast glaze. I've done my own programming for the bisque firing (mainly on the slow side) but was wondering what the difference is in the glaze firing. Why would one choose fast over slow or vice versa (sp?). |

I have a kiln with a controller like that and I always use the slow bisque.
Still had two pieces explode last night. I think you would use the fast bisque when you have a small load and you know the pieces are totally bone dry. Sandi "Doug Porter" wrote in message ...

I don't think you can take the early stages of a bisque firing (up to
red heat) too slowly. Steve In article , sandi writes I have a kiln with a controller like that and I always use the slow bisque. Still had two pieces explode last night.

I take bisque up 100C per hour to 600C then flat out to !000C this works for my own usually quite fine work and my childrens classes work. I rarely get anything exploding, I am careful about air bubbles in my own work and the childrens work though. For glaze I take it up 150C per hour to 300C then flat out to what ever temp/cone suits the clay and glaze. Annemarie |
