Fellow clayarters,
Two questions: 1) does anybody have any experience with or tips to offer
about cone 9-10 matt red glazes. A fellow potter and I were talking about
red glazes and wondered why we hadn't ever seen and high fire matt reds.
2) The recent rather unhelpful Ceramics Monthly article on Chen Wen's iron
crystal glazes was nontheless a bit provoking. I tried the ancient Chinese
recipe for iron crystals, but met with failure, despite a 5 hour soak to
encourage crystal development. The recipe failed to mention what kind of
feldspar to use, nor did it mention anything about firing methods. Does
anyone have any suggestions or advice? Thanks, -=Rick=-

A little beacon among the NCECA highlights was meeting Chun Wen Wang, and
talking glazes with him, in addition to ogling the dozen or so little
winners he'd set up in a case and in boxes. This guy is a mis-cloned
Pete Pinnell! (He doesn't resemble Pete physically, but he's superbly
well-informed and articulate about what he knows.
I'd suggest getting in touch with him about questions you might have
regarding the article in CM.

One of my students tried the crystalline iron glaze from CM.
The crystals that were achieved were much smaller than those
shown in CM, but were definitely there. I did not have time to
soak the kiln for more than an hour, and as it is an old updraft
with floor burners, cannot be slowed greatly in cooling. We
built a small saggar in the bottom of the kiln, and fired some
pieces there. The best and largest crystals were achieved on
pieces in the saggar, where cooling was slowest - as one might
expect. We found the glaze a bit flat and uninteresting where
no crystals grew, but rich where they were. More experiments
will follow, undoubtedly. We'll try relighting the kiln at
some point in the cooling, to slow it a bit more. Perhaps a
ceramic blanket on top, to slow incoming air around the burner
ports...the students will undoubtedly think of more things to
try than I will. If/when things work, will let you know.

I altered Reitz M-2 Green Matt to get a matt red:
Neph Sy 70
Whiting 5
Gerst. Borate 2
Petalite 15
OM-4 8
Tin Oxide 3%
Copper Carb 1%
Have Fun! Fire to Cone 9 - 10 with reduction.

Clayarters :
One of my students mixed up a small amount of iron crystal glaze from
recent CM. I put it on a white stoneware tile and a grolleg porcelain tile. I
placed on kiln shelf alone and in saggers and fired to ^ 11 reduction in 14
hours and cooled for 60 hours.
No luck. Does not appear remotely like photos in CM. Obviously, a
different firing cycle is needed for formation of crystals. Unfortunately,
article does not elaborate. It is a bright, and I do mean bright, Ohato Kaki
red. Much brighter than Kaki's I've known. Which is alright if you're
looking for that kind of color and texture.
