FULLN CHEMICAL enamel pigments Maroon (Chrome-tin red) FU-E105 is an inorganic pigment synthesized by calcination at high temperature. It is a red pigment obtained by mixing, calcination and micropowder treatment of raw materials such as tin oxide, calcium carbonate, quartz and chromium oxide. In the process of calcination at high temperature, tin oxide, quartz and calcium oxide form the crystal structure of calcium spicite, and fine grains of Cr2O3 are evenly dispersed on the matrix of calcium spicite.
