Description: You are buying 1 pound of Opax Zicronium Oxide powder to opacify clear glazes. Other Opacifiers are Ultrox Zicron, Tin Oxide etc. Opax is a brand name for Zirconium oxide opacifier. This will increase the viscosity of the glaze. It also can be used to make matt glazes. This makes a very hard glaze.OpaxOxideAnalysisFormulaNa2O1.11%1.00ZrO290.84%41.18Al2O30.91%0.50SiO26.48%6.02Oxide Weight5,548.72Formula Weight5,548.72There are three main oxides that are used as opacifiers: zirconium, tin, and titanium, although bone ash in small amounts also will opacify a glaze, but that's not all it does. Ultrox, Zircopax, Opax, Superpax are all brand names of zirconium compounds. One of them, Opax is zirconium oxide; the rest are zirconium silicate. If all you're doing is making a glaze white and unvariegated, zirconium will do it. If you want a bathtub white, this is what you're looking for. It's the cheapest opacifier. Tin oxide will produce a mellower white if you're just opacifying a white glaze, and will produce a warmer white than zirconium. It also has a different effect on some colors than zirconium, particularly iron. Titanium, whether pure in the form of titanium dioxide, or in the form of rutile (which is theoretically 92% TiO2, and 8% iron) both opacifies and breaks up the surface, producing microcrystals. Which one is best? As usual, it depends. Paul Lewing, Seattle
