SIO-2 - Stoneware Paper Clay - PCLI (0-0.2mm) - 1100-1260°C - 12.5Kg

Stoneware paper clay bearing grog 0-0.2 mm. Formulated for artistic ceramics, it is unique for modelling, thanks to its exceptional plasticity. It is specially 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. Odourless. Available in extruded body (moist form).
