In the late 60's my ceramics class did a Japanese Raku tea ceremony. We didn't have a charcoal fire, we used a small kiln. The cups were made by hand with Raku clay just as they were in the ceremony in the 1500's. They were taken out of the kiln red hot. They sat and cooled down to the point they could be dunked in a bucket of water. We didn't glaze them with a lead glaze like the original ceremony. They all survived even though everything was rushed, it was only a hour class. Denice

The REAL thing. Wonderful.

“The quickest firing I’ve done is a wet pot off the wheel into a red hot kiln. Bisque ware in 30 minutes.“
Hi Kelly,
I came across this in a post of yours, from 2022, in the “Fast Firing” discussion.
It’s not that I want to do this, it’s just that I would love to hear more of the whys and hows of the situation that allowed this to be successful!
Thanks,
Karen

Someone told me it was possible, I figured I'd try. I had a little test kiln. Just had to see it, no good reason why. It's completely impractical.
So I got the kiln hot, threw a little cup and set it on a chunk of kiln shelf. I set that on another shelf, so I could slide it into the kiln, pushed it in with a stick.

I just read your message on firing to avoid pinholes and bumps in cone 6 and you mentioned a drop and hold firing schedule and showed a beautiful mug. I’m holding for 20 minutes at the highest temp and it looks pretty good but wondering if you suggest dropping to ? temp and Then holding? Hold for how long? Thanks!!

Oh, sorry, that just means shutting it off. Old term from gas, oil, and wood kilns where you would make sure the damper is shut and other openings are closed off at the end of a firing.

Because bumps, blisters, and pinholes are related (not the same, mind you!), one fix people try is to drop temp 100° F and hold there before clamming up the kiln. It’s what I do with my local glaze that pinholes a lot.
