Abstract

The invention relates to a non-toxic famille rose pigment and a preparation method thereof. The pigment adopts natural raw mineral materials and industrial chemical raw materials, and comprises the following components in percentage by weight: 25 to 40 percent of quartz, 10 to 20 percent of feldspar, 20 to 30 percent of boric acid, 5 to 15 percent of alumina, 2 to 6 percent of lithium carbonate, 5 to 15 percent of light calcium carbonate, 0 to 3 percent of talc, 2 to 8 percent of zirconite, 3 to 6 percent of tin oxide, 0 to 3 percent of titanium oxide, 0 to 2 percent of cerium oxide, 0 to 5 percent of barium carbonate, 0 to 3 percent of magnesium carbonate, 0 to 5 percent of potassium nitrate, and 0 to 5 percent of sodium fluoride; and 0.5 to 2 percent of coloring metal oxide or 10 to 20 percent of nontoxic ceramic pigment are additionally or directly added into the components to prepare the product. The method well solves the problems that the famille rose is not white, famille or tender, has high expansion coefficient and the like after lead and arsenic are not added by adopting composite opacifier and controlling the proportion of flux components so as to prepare the non-toxic famille rose pigment with traditional famille rose decorating effect of Jingdezhen.
