Well, I'm kind of like the new old kid on the block, as regards to shino
and carbon trapping, but my last few firings have given me very good carbon
trapping with crystals. So I thought that I would pass on my method. And
thanks to Malcolm Davis as I cornered him at NCECA before I got my Bailey,
to pick his brains on his firing schedule. This is what I did the last two
firings.
Went into heavy reduction at cone 010, just when the cone was starting to
tip on the top shelf. I kept it in heavy reduction until around 1100 C,
eased up a bit, but still in light reduction. When cone 8 was starting to
tip I put it in heavy reduction again for about 30 min. There was black
smoke coming out of the top of the door during body reduction and during
the glaze reduction. Not a lot, but some. No smoke coming out of the
chimney. I turned the kiln off when 9 was 3/4 down, (my Bailey is hotter
in the back half), and I crash cooled for 5 min., spys, chimney, and burner
ports.
Some of the crystals were on porcelain and some on stoneware. The
stoneware went a beautiful patterned goldish glaze, and the porcelain went
grey, black, orange, white, with black crystals surrounded by white and
orange. I'm still shaking my head. It's Malcolm's carbon-trap shino #2.
And it wasn't a fresh batch, but one I made in the spring. I glazed the
same day that I stacked the kiln, pilots on low one and two nights.
The shino is best in the front half of the kiln. It's all a mystery to me,
but I love it!,,,,when it does the right thing. Liz
