A pictorial pigment obtaining method comprises charging material grinding, and thermal treatment till baking, and chopping and grinding the baked product. Prior to the thermal treatment, the obtained mass is passed through a sieve N70 (4900 holes in 1 cm2). Thermal treatment is carried out till uncomplete baking at the temperature of 900-1400°C in presence of pearlite. The grinding of the mass is carried out for obtaining as small particles as the rest on the sieve N 100 (10 000 holes in 1cm2) would not exceed 0.5 %.
