Recently I ended up firing several kiln loads of
pots that were a mix of my regular stoneware, porcelain and the high iron
stoneware that I have been making up myself in small batches of about 40 to 50
pounds of clay at a time. The reason I even mention this is that I am pleased
with the variety and range that I get from the glazes I use on the pieces
making it seem like they are different glazes as opposed to different clay
bases which alter the appearance. The only real exception to this is the use of
my temmoku on the two stoneware bodies where it comes out almost identical but
on the porcelain it is just a tiny bit translucent making for an interesting
effect especially over stamped decoration. The illustrated Oribe style jar was
thrown out of the iron stoneware and then had a thick band of combed slip
applied, over the slip it is an intense, mottled green but over the rest of the
body it has a thick, deep green appearance with mossy tendril effects from the
additional iron in the clay mingling with the glaze. Though it isn't terribly
different then the effects on the regular stoneware it is just different enough
to create a surface and appearance that is both related but apart from one
another providing just another avenue to explore in the ongoing search to see
what else I can get copper to do.
