If anyone on the list has worked with inclusion pigments, I would
appreciate any information you would be willing to share. I am working on a
porcelain project at cone 10 for a client and would like to expand the
color palate options. I have received some information from my friend John
Williams at Trinity Ceramics and would like to broaden my information base
from those of you who have some hands on experience with these materials at
this temperature in a reduction atmosphere.

I use the inclusion pigments in cone 10 reduction, wood fired - quite a
harsh enviroment for preserving color. THEY WORK. The colors are probably
not as bright as they would be in low fire oxidation, but you definitely
have red, orange, and yellow. The orange is not that striking because we've
all seen nice rutile oranges in ^10R. The red is more like a brick red than
a primary red, with not as much personality as a good copper red. The
yellow, however, is unlike anything I've ever seen on stoneware: a true
primary yellow. Use your good artistic judgement here, or you could move
into the monstrosity area in a hurry, or, put another way, "less is more"!
I use the pigments only in slip-glazes, painted on wet pots, just as I use
more traditional stains. I did, however, do some glaze tests for our mutual
friend John Williams, using a typical high magnesia semi-matt, with good
I also did tri-axial color blends between the three colors. This was a
dead-end, as I mostly just ended up with orange. I think you could use the
pigments just like oxides or stains and blend them with other oxides to
create new colors or subtile varations. Start with 5-10% in a glaze, 10-15%
in a slip.
I would enjoy hearing back from you if you do some test firings.

Jonathan, Karen Gringhuis has worked a LOT with CERDEC zirconium
incapsulated cadmium stains. Infact, Clay Times had an article a few years
ago about her work and experimentation. She fired to C10 oxidation and
reduction (if I remember the article correctly) on white stoneware and the
colors are magnificent and bright reds, yellows and oranges.
I've played with the red stain and man it is fire engine stinkin' red.
mixed with my white base glaze I got carnation pink. With clear base the
stuff is RED. If you get some to play with, get the stains with the longer
for higher firing. Continental Clay carries the CERDEC stains. Talk to
The Arlington Pottery

Jonathan - Cerdec incl. pigments have worked fine for me in redtn. but
the colors are a bit grayer & more subdued than in ox. Can you be more
specific as to what you want to know? I did a lot of tests in different
bases which I still have. On porcelain & on dark stoneware. I'd
be happy to help (I owe you one) but am not sure what you need to know.
Talk to me. Karen Gringhuis 607-587-9624 or here
