Stoneware Paper Clay with Impalpable Grog
Stoneware paper clay body with 30% impalpable grog (up to 80 Mesh). Formulated for artistic ceramics, it is unique for modelling, thanks to its exceptional plasticity. It is especially suitable for making impossible shapes with difficult drying. The presence of paper fibres inside avoid formation of cracks and problems of deformations, and leads PCL clay to surprising artistic possibilities. Odorless. Available in extruded body (moist form).
