Lithium Tetraborate Fluxes

General purpose acidic fluxes for fusing aluminosilicates, basic oxides, carbonates, ceramics, cement, glass, rare earth oxides, refractories, soils, and steel. Not suitable for highly acidic samples. Samples must be fully oxidized. VFLUX-312PF is typically used for cements. VFLUX-313 is typically used for ceramics.
