A very good firing before the Chatham show
Yesterday's firing went smoothly after an early re-light in the first hour. After that, the kiln climbed smoothly, with a heavy reduction beginning at cone 012 and then a lighter reduction throughout. Good shinos, good copper reds, good temmokus.
The new pyrometer installed by Jim Akens showed that it takes a few hours for the bottom of the kiln to catch up with the heat of the top, but it also showed that maybe four hours into the firing the top and bottom were within two or three degrees of each other. I more or less guessed this was the way things went, but it's good to see it documented digitally. And in the end, the cones agreed with the pyro.
I'll attach some photos: three of teabowls, most of them shino with sprinkled wood ash, but a few temmoku, Antarctic ash and Shaner Red; one of altered cylindrical shino vases; one of three pots which started fired life as pale, oxidized shino and came out richly ironed by the red primer paint they were sprayed with before a second firing.
Tomorrow I'll be on the road well before sunrise to get to Chatham - many miles down-Cape - for the three-day Creative Arts Center art show at Chase Park. Come on down if you're in the area.
