Primo Pro PCL Paper Clay is a Stoneware paper clay bearing grog 0-0.2 mm. Designed 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 day to a surprising artistic mean of expression. Odourless.
