Hi Mark,
I have recently decided to wait 36 hours before opening the kiln. It
usually goes off at about 7P.m., and I leave it until the second morning
after.
My colors are really much improved. By then, it is more like 180 degrees.
It is worth the wait.
Best, Rikki

Mark, I don't even think about opening the kiln until I can stick my finger
in the top peep hole and hold it there. The pots are still beautifully warm
without all the "pinging".

Hi Mark,
Next to pricing pots.. waiting to open is the next toughest for me.
I try to think about and do something else until all is just comfortable to
take out with thin gloves or bare hands.
I am glad to now have my own kiln, so don`t feel pressure with the guild
time table.
Had too many plings and noises by being anxious and it pays in the long run.
A funny story.. Our guild had a workshop by exchange potters frpm Spain. He
got his pots out fast one time..had to take them down the mountain to sell,
got his car set on fire in the back..
Not good. But why I make myself wait is because the glaze and the clay often
want a little more time.
From Lela where cool down is going on all over..friggin freezin here.

We take the pots out when they are still a little uncomfortable to hold
in the bare hand, we would no more leave a kiln to get cold before
unloading than we would leave scones in the oven to get cold.

Mark, I've developed a system for opening around 250 degrees F.
When I took the pots out and put them on a cold shelf at room
temperature I would get lots of pinging, so here's my new method. I
fire electric and all my shelves are half shelves, so as I open the
kiln I see shelves number 1 and 2, let's say. After admiring the
pots on those shelves I move them all to shelf 2 and remove shelf 1
which exposes the pieces on shelf 3. I carefully stack all the
exposed pieces on shelf 3, remove shelf 2 and expose shelf 4.
Continue this way until you've looked at all the pieces and all the
heat-holding shelves are removed.
The pots are still warm from their stacked heat and the heat on the
inside of the kiln so they don't get a jolt of cold air. You have
had a chance to see the pots and now they can cool further in the
kiln. You can close the top again to slow down the final cooling or
leave it open. The heat from the kiln will still let the pots cool
more slowly than they would if they were removed into the open air.
Whether this would work for you depends - do you fire electric? This
would be much tougher to do in a gas kiln. Do you use half shelves?
Is it just impatience to see your latest work or do you have to
unload to take the pieces to a show? At any rate, for what it's
worth .........
All the best,

I pull my pots anywhere from 400 down, just depends if I have a show or sale
coming up soon.
I figure if they can come out of the oven at 400 they can come out of the
kiln also.
That's my story and I'm sticking to it!!!

Well, Mudducks, Sounds good, but not to mislead newbies, pots taken
from the oven usually have food in them to temper them from any cooling
shock. Another trick I learned at Cranbrook was to always turn the pot
upside down so the heat would be captured inside to slow down the
cooling.
