Boxes are 20kg (22.68 lbs). Plus there are enough trimmings to make about two more. That is about 500g of pugged clay per mug. These have been trimmed and engobed (using our standard cone 6 engobe) and are drying. Notice I have waxed the outers of some of the handles to slow their drying down (to keep it in sync with the mug itself). M390 is likely the most plastic native Plainsman body. Although it was not overly soft I stiffened up the clay for ten minutes on a plaster bat to make it my ideal throwing stiffness.
Plasticity (in ceramics) is a property exhibited by soft clay. Force exerted effects a change in shape and the clay exhibits no tendency to return to the old shape. Elasticity is the opposite.
