Fluorspar
Can be used in glazes as a substitute for whiting, promoting more fusible glazes. Fluorine combines with silica in the glaze and burns off as a gas, which may cause blistering. Pin-holing can occur in glazes if the mesh size is not lower than 100. Low fluxing temperature. CAN BE DESTRUCTIVE TO KILN FURNITURE OVER LONG-TERM USE.
