If one mixes fluorite with concentrated muramic acid, will the resulting solution dissolve glass? Or clean gold?
I think HF has less dissociation in water than HCl- so HCl plus CaF2 should result in some HF and CaCl2- I just don't know how much.

Hydrofluoric acid is produced by treatment of the mineral fluorite (CaF2) with concentrated sulfuric acid. When combined at 265 °C, these two substances react to produce hydrogen fluoride and calcium sulfate according to the following chemical equation:
CaF2 + H2SO4 → 2 HF + CaSO4
