Wollastonite is a natural compound combining calcia and silica. Wollastonite does not include elements that form gases during firing which leads to a smooth glaze surface without pinholing. With relatively low melting point, wollastonite acts as a powerful flux in ceramic glazing.
WARNING: Contains free crystalline silica, which could lead to silicosis or other lung diseases after very long exposure. IRAC has classified crystalline silica as a carcinogen, based on evidence of carcinogenicity in experimental animals and limited evidence of carcinogenicity to humans. Wear a NIOSH approved respirator. For further information, contact: Rovin Ceramics at 734/424.3345
