Athena Porcelain Paper Clay (5kg) 164-ATHE
Recommended firing range 1230-1270C / Cone 7 to 9
Indicative texture 1 (Smooth 1-Coarse 10).
Athena is a translucent white porcelain paper clay with outstandingly high plasticity, making it ideal for modelling.
It is specially designed for creating forms which would be impossible with porcelain.
The presence of paper fibres within the body reduces the risk of crack formation and warping problems.
Supplied in a 5 kg bag.
