Well Janet, I was never taught to wait until bisque-fired
and glazed pots were dry before firing, so I never even
considered waiting. Never had a problem.
I sometimes need one more pot a certain height to finish out
a stack, so I go in and glaze one, stick it immediately in the
kiln, brick up the door, and start firing.
And I don't tarry; I have red heat after a 1 hour warm-up
and 3 hours of firing.
I consider bisqued pots to be the toughest pots, as far as
taking the thermal abuse of quick and/or uneven temperature
changes.

| Hi David,
|
| I was surprised to hear you saying: >>If you load your kiln with pots that
| have been glazed the same day they are much wetter than your kiln shelves
| will be.<<
|
| I was always taught to make sure glazed pots were well and truly BONE DRY
| before firing. Does your experience mean that is just one more pottery
myth?
| I would be interested to hear, because I was convinced that some glazing
| problems discussed on this list are really due to overlooking this "basic
| rule".
|
| As for the original question on wet kiln shelves... I am sure you are
right
| about a biscuit firing sorting out any problem without any worry.
