Controlled Cooldown


Sunny

Recommended Posts

Slow cooling is done for the glazes. Some like it, some don't. It's worth testing both ways to see how your glazes react.

 

The outside temperature will not affect cooling time all that much at high temps when it will have an effect. If your controller is unhappy about the cold temps, put a space heater  near it for a while before starting the kiln.

I'm using the program that was recommended in the book that came with my kiln. The slow glaze firing. It had a hold temp of 5 minutes, I did 10.  And I left the top peep hole out. Is that right?  The kiln temp when I turned it on was 55*.  The next time I do a glaze firing, I'll skip the cool down and see if there is a difference. I would imagine it would be a great thing for doing glass firing. I did that in my manual kiln, it had a lot of crazing. I don't know if that was why or just me being an amateur at it.
