Traditional white earthenware clay. High whiteness when fired in an oxidation environment.

It is very suitable for the use of traditional pottery glazes and colouring oxides. 

High fired bending strength see specifications below.

Available in an extruded body, suitable for wheel-throwing, shaping and modelling.

Firing range* (biscuit): 1050-1080ºC/ Cone 05-04
Water content (throwing): 22%
Plasticity (IP Atterberg): 14
Carbonate content (CaCO3): 14%
Drying shrinkage: 6.2%
Firing shrinkage 1050ºC: 0.8%
Porosity (water absorption) at 1050ºC: 14.4%
Dry bending strength: 6.8 N/mm2
Fired bending strength 1050ºC: 32.2 N/mm2
Thermal coefficient 1050ºC (25-500ºC): 72.3x10^-7ºC^-1

(*) Firing range recommended for the clay to develop its best performance, both in terms of technical and safety characteristics, under conventional firing conditions. The colour samples may show temperatures outside the recommended range to provide a broader view, but these are pieces fired under controlled conditions. Cone equivalence according to Orton table for self-supporting cones, regular-SSB and 150ºC/hr heating rate.
