Talc
SKU: 72180-1LB Brand: Seattle Pottery Supply
$5.17
Talc (Mg₃Si₄O₁₀(OH)₂) is a magnesium silicate mineral used in ceramics as a flux and a source of magnesium oxide. It helps lower firing temperatures, improves thermal expansion control, and contributes to matte surface effects in glazes. In clay bodies, talc enhances strength, reduces shrinkage, and improves thermal shock resistance, making it a common ingredient in low-fire earthenware and industrial ceramics.
Dust can cause respiratory irritation and may contain trace crystalline silica. Always wear gloves, a dust mask or respirator, and work in a well-ventilated area. Avoid ingestion and wash hands thoroughly after handling.

My expiring stock of talc is deep gray in color, I just opened a bag of talc from Seattle Pottery Supply and it is white. Is this a talc substitute of mag carb and silica or a legitimate talc? My understNDING IS THAT MAG CARB IS SO LIGHT IT FLOATS TO THE TOP OF A GLAZE MIX creating problems in a non-uniform mix. So is this truly talc? Thanks
Yes, this is talc, we sell exactly what is on the label
