Cajonat got a reaction from Pres in Smacking head...accidentally set my switches to high, not low
Ugh...glazes crawled that don't normally crawl. My smokey merlot rims jumped off onto the shelf. Witness cones were all over the map. I have my loading and shelf placement down pat so can almost always get a consistent fire. I had cone 7 bent over, cone 5 barely bent over, one shelf a perfect cone 6. And some of my pots looked a bit warped. So chalk that up to never do that again...

There should be no problems, and don't get anxious. . . .if you open too soon you'll getting cooling dunts which can be really devastating. Wait until the kiln is cool, vent a bit, and wait until heat coming from vent space at lid and peeps is slightly warm on the hand.
best,
Pres

@Cajonat if you haven’t yet, make sure you let Plainsman in Edmonton and Ceramics Canada in Calgary know you’re selling these. They’ve both got bulletin boards for used equipment, and stuff goes quickly.

Cajonat reacted to Marcia Selsor in QotW: What process do you use with the clay you use, including glazing and firing range?
I have been working with Coleman Porcelain to use in Obvara as well as sagger and soluble salts. This is not fired to maturity. Porousity is needed for the absorption in the lower temperature.I have been testing numerous ^6 porcelains to use in this process also. I have Linsay Porcelain ^6 from Archie Bray Photo#1 and a ^6 Plainsman Translucent porcelain for actually firing to ^6. #2 was fired yesterday using soluble salts.I fire soluble salts from 1250F to 1700 depending on the colors I am trying to get.

Working with a coarser clay makes the smooth process a little slower, I got into coiling when I was in college. I took a archeology class that was in a competition with other colleges to replicate Anazai pottery. It was held in the pottery studio and I was the only clay person in the class. The professor taught the class how he thought they made the coiled pots, I told him he was wrong that the pots would crack and fall apart. At the end of the semester we fired them in a trench firing, my work come out fine the rest was broken shards. I had a dozen pieces come out of the firing most of them quite large and thin walled. The professor admitted I was right, the archeology department won the competition with my work. Denice
