Name
SIO-2 ARGILA  Clay (100% natural pottery clay)

Formula
SiO2 (53.53%), Al2O3 (20.50%), Fe2O3 (0.67%), TiO2 (0.98%), CaO (8.58%), MgO (0.30%), Na2O (1.17%), K2O (2.20%), L.O.I (11.63%)

Description
SIO-2 ARGILA is a 100% natural pottery clay, very pure and fine milled clay in white color. Its plasticity is well balanced in order to achieve best results during the modeling, drying and firing. The color remains intact after firing (recommended to be fired in a kiln between 970 and 1050ºC)

Extraction Process
SIO-2 ARGILA  Clay is a 100% natural product, composed only from clay (chemical analysis shown in Formula) and water
