Взвешенные в необходимых количествах сырьевые компоненты (кварцевый песок, глинозем, доломит, поташ и др.) измельчают в шаровой мельнице, смешивают. Полученную смесь подвергают термообработке в окислительной среде при температуре 1200-1240°C с выдержкой 30 мин при максимальной температуре. Массу размалывают до остатка не более 0,1% на сетке №0056. Полученный пигмент смешивают с глазурью (эмалью) и наносят на керамические изделия, например, способами пульверизации, ручной росписи, прямой печати, деколя и т.д., после чего закрепляют обжигом в окислительной среде.Weighed in the required quantities, the raw materials (quartz sand, alumina, dolomite, potash, etc.) are crushed in a ball mill, mixed. The resulting mixture is subjected to heat treatment in an oxidizing environment at a temperature of 1200-1240 ° C with a holding time of 30 minutes at maximum temperature. The mass is ground to a residue of not more than 0.1% on mesh No. 0056. The resulting pigment is mixed with glaze (enamel) and applied to ceramic products, for example, by means of pulverization, hand painting, direct printing, decal, etc., and then fixed by firing in an oxidizing environment.
