Porcelain paper clay
Cellulain® is a translucent white porcelain paper clay which stands out for its high plasticity, what makes it exceptional for modelling. It is especially designed for creating impossible shapes with porcelain. The presence of paper fibres inside avoid formation of cracks and deformations problems. Its formula is very stable and provides a secure firing range between 1230 and 1270ºC. Available in extruded body. Presented in a practical 5 kg cylindrical format with double packaging.
