Hello , may name is Mark Herman and I have been making pottery for about 6
years along with neon, glass sculptures and other art forms. I have been
using bag clay for all this time and have just graduated and now have a
mixer and pugmill , (soldner and venco) I don't know much about mixing
clay but I have reclaimed so great stuff. I find the clay is much more
uniform and easier to throw.. If anyone knows a formula for white
stoneware that is good for raku and functional pottery I would appreciate
the response.... I don't use much grog and I like a clay that can be
thrown soft and still have the stability and ability to be thrown thin..

Mark, I make the clay for Sul Ross State University Ceramics Department
and this is the recipe that we use:
Missouri Fire clay 100 lbs.
Gold Art 50 lbs.
Kentucky Ball clay 30 lbs.
Custer Feldspar 10 lbs.
Grog 10 lbs.
--------
200 lbs. of dry
We mix in about 100 lbs. of reclaimed scraps, so this recipe has the
potential to make 300 + lbs. We sometimes play with this recipe a little
to get just waht we want. Hope this helps. Jennifer Alpine, TX
