sargeant on sat 15 nov 97

Hi i just recently moved to Texas from Canada fortunatly i ended up at a
place called the ART STUDIO in Beaumont
The studio has a wonderful clay department and a truly inspiring director
in Greg Busceme
This summer we built two new kilns for the studio a salt kiln and a gas
reduction
We have fired the salt kiln about eight times but we still seem to be
having problems with getting a kiln wash that is easy to apply
We use alumina mixed with a small amount of ball clay to help keep it
suspended in water
any sugestions would be apreciated

Noel: I don't understand why you use a kiln wash We don't (Mel & I at
the "farm"). We wad the pieces with a mix of half kaolin and half
alumina hydrate and scrape our shelves (rub vigorously with a broken
piece of silicon carbide kiln shelf) after each firing. We often dip
the end of posts in a thin mix of the wadding mix ("smart pills").

This wash works well in salt and doesn't peel.

alumina hydrate(100mesh) 75%
kaolin 25%

Apply a thin coat over existing coats prior to each firing. When the
buildup is over a quarter inch or so remove all wash with a wire brush head
on an angle grinder and start over.

I don't know why anyone washes shelves at all. I don't. I know my glazes, wax
properly, and just set them on the shelf. If the shelf starts to warp I can
just flip it over. Haven't washed shelves in 20 years.

Noel: I have always made my own kiln wash and it consists of 50% Silica
and 50% EPK. I have never used it in a salt kiln, but it works great in a
gas and in electric kilns. Hope that helps, Jennifer in Alpine, Tx
