Strong flux for glazes: Enables effective melting at 1472°F for advanced ceramic work
Improves glaze brightness: Produces more vivid, eye-catching ceramic finishes
Expands firing range: Allows for a wider temperature window during glazing
Reduces thermal expansion: Minimizes cracking and warping in finished pieces
Summarized by Shop
It is a source of Lithia for glazes. A strong flux, beginning to aid in the melting of glazes at 1472°F. Used extensively as a secondary flux in leadless ^06 and ^5 glazes. Improves the brightness of glazes, and increases the firing range. Also reduces thermal expansion of glazes.
