SIO-2 clay is produced in Spain by Cerámica Collet S.A.
BEGUR is a porcelain that stands out for its pink tone when fired, inspired by the characteristic hues of the Costa Brava granite. It offers high plasticity, making it ideal for wheel throwing and hand modelling. Its formula is very stable and allows a safe firing range between 1200 and 1240 ºC (oxidising atmosphere). Suitable for tableware (food-safe), according to ISO 6486. Available in extruded body (moist form). Supplied in a 5 kg cylindrical format in a carton box.
