Material Notes:

Thomas clay is similar to Volunteer clay and has established an excellent history of performance in stoneware and low fire (talc base) plastic and casting formulas. The diverse combination of clays provide enhanced plasticity to a ceramic composition through increased particle packing density. Thomas clay has very good fired brightness and oxidation qualities.Information provided by Old Hickory Clay Company
