UPSALA blue porcelain 5kg

UPSALA is a unique blue porcelain noted for its beautiful cobalt blue. It has high plasticity, which makes it ideal for wheel-throwing and modelling. Its formula is very stable and provides a secure firing range between 1200 and 1240ºC (oxidizing atmosphere). Suitable for tableware (food-safe), according to ISO 6486. Available in extruded body (moist form). Presented in a 5 kg cylindrical format in a carton box.

Available in the United States and Canada. ACMI AP Seal. Conforms to ASTM D-4236.

(*) 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.
