I hoping that some one out there has both heard of Troy slip and has a
recipe for cone 10 reduction firing. We have a small batch here at the
college but no one knows what it is or where it came from. A student began
to use it as a thinly applied under-glaze. It provides beautiful flares of
iridescent blue under both celadon and glazes containing Rutile. This makes
me think that Rutile may be part of the formula. My search on Google has
come up empty. I hope that one of you potters is familiar with this and can
solve the mystery of Troy slip.
Love and Peace,
Maura

Hi Maura,
I will look for the formular. I haven't used it in awhile. It is rutile,
red iron oxide, and maybe neph sye. I used it as an on glaze slip. [I do
all my decorating on top of the glaze.]
It was very pretty, but a change in rutile made it less interesting to me.
More tomorrow.
Rikki

Maura,
The old name for Helmer Kaolin is Troy Fireclay manufactured by the A. P .
Green refractories company before they went out of business in Troy, Idaho
in the early 80s. That was the reason I began to manufacture and sell Helmer
Kaolin under the current name (it is mined near the town of Helmer, Idaho).
The clay was mined there and hauled to Troy for dry pan processing and for
the production of super duty fire brick that you know as YUKON fire brick.
The pit has huge reserves (over 1.6 million tons of the current analysis)
that are well documented through bore hole exploration.
The color reactions you see come as a result of a combination of colloidal
iron seeping down from the Palouse formation into the high grade white
Kaolin and the presence of some Titanium Dioxide in the clay.
Regards,
Michael Wendt

Maura; I by Helmer clay from Idaho marketed by Plainsman Clays of Medicine
Hat, Alberta, Canada under the name of Troy Kaolin. Maybe this is your
mystery slip.
Cheers,
Tony

What cone is this slip? Is it vitreous at the proper cone? Do you use
the slip under glazes? If so, how does it react? Thanks for sharing your
recipe.
