MARBLEX 5 LB. by AMERICAN ART CLAY
This gray, self-hardening modeling clay is prepared in moist form, ready to use for all methods of modeling, including wheel throwing and sculpting. When completely dry, finished pieces are durable but not waterproof. Knead MarblexTM to increase plasticity before modeling. Keep unused clay in a plastic bag or wrapped in damp cloth to prevent drying out.
