The only possible substitute is cryolite (sodium aluminium fluoride) which is 32.8% sodium, 12.8% aluminium and 54.4% fluorine. Any glaze where cryolite is substituted for fluorspar will have to have substantial adjustments to replace the lost lime and more anti-flux added to compensate for cryolites greater fluxing power.

Fluorspar Statistics and Information - USGS

Fluorspar is used directly or indirectly to manufacture products such as aluminum, gasoline, insulating foams, refrigerants, steel, and uranium fuel. Byproduct fluorosilicic acid production from some phosphoric acid producers supplements fluorspar as a domestic source of fluorine, but is not included in fluorspar production or consumption calculations.

Fire Assay Flux & Litharge Composition

The following remarks on the use of the fire assay fluxes and litharge may serve as an aid in arriving to a correct composition of charges for most cases:. Litharge or red lead is added in the proportion of one or two parts to two of ore; if too much litharge (lead oxide) is used the slags are not clean, as a slag containing lead may mean a loss of silver and gold.
