What temp do you fire pottery at?

In modern societies pottery and brick is fired in kilns to temperatures ranging from 1,800 F to 2,400 F. Most of the common clays like clay shown here on the left found in our back yards start to deform and melt if they are fired higher than about 1,900 F.

At what temperature can I open my kiln?

Don’t open the kiln until it is below 150-250 degrees F, or thermal shock may hurt the ware and/or the kiln elements. You should be able to touch the pieces before you unload them. It almost never hurts to fire a kiln slower rather than faster. The exception is some glazes that will look better if fired fast.

Which cone temperature is the hottest?

The hottest is 10, going downward to 1. Then as it continues to getting cooler it continues at 01, 02, etc. So there is a BIG difference between cone 5 and cone 05! In standard firing, cones of the right number are placed around the kiln and are watched.

Can you fire Cone 10 clay Cone 6?

You cannot fire a clay higher than its maximum-rated Cone, or it will melt. Cone 10 clay can be used at low fire (Cone 04-06 or at Cone 6), but to reach its maximum strength it should be fired to Cone 10. That will cause the clay to shrink and become dense, and that is ideal, especially for dinnerware.
