Chrome Oxide Twenty Five Pounds
Chrome Oxide Twenty Five PoundsCHROME OXIDE - Cr2O3 (m.p. 4418oF/2270o C) is used (in small amounts <2%; it is very refractory) as a colorant to produce greens. However, this Oxide has a chameleon-like effect on glazes depending on the choice of temperature and flux source, i.e. KNaO, CaO BaO, or MgO. Used in combination with Tin, it will produce pink, and with Zinc Oxide it will produce brown. Bright reds are possible in low-fire lead glazes that are low in Alumina content.
