This porcelain clay body is vitrified and pretty translucent at cone 10.

Mix the Veegum T and the Bentolite L together in two buckets of water and pour them in the mixer after the dry materials are thoroughly mixed. After mixing, run the clay through a pug mill. To increase translucency, add a few more percentage points of Custer feldspar and silica.
Note: This will also result in slumping over the foot ring of plates and bowls, and a tendency of the clay to stick to the kiln shelves. To prevent sticking, add a little alumina to the wax applied to the feet.
*Axner/Laguna sells Bentolite, a white-burning, calcium-type, refined bentonite that doesn't swell, shrinks less, and does not cause speckling like regular bentonite.
