Production. Lithopone is produced by coprecipitation of barium sulfate

barium sulfate
Barium sulfate (or sulphate) is the inorganic compound with the chemical formula BaSO4. It is a white crystalline solid that is odorless and insoluble in water. It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it. › wiki › Barium_sulfate
and zinc sulfide
zinc sulfide
Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite. ... In its dense synthetic form, zinc sulfide can be transparent, and it is used as a window for visible optics and infrared optics. › wiki › Zinc_sulfide
. Most commonly coprecipitation is effected by combining equimolar amounts of zinc sulfate and barium sulfide: BaS + ZnSO4→ ZnS · BaSO.

Is zinc sulphide barium sulphate pigment mixed?

White pigments include TiO2, zinc white (ZnO), zinc sulfide and lithopone (a mixed pigment produced from zinc sulfide and barium sulfate).

Why is ZnS white?

As the size of the cation increases, upon moving down in the periodic table, the overlap between the orbitals decreases and the band gap shifts to lower energy. Since, the band gap decreases from ZnS to HgS, the colour of ZnS is white, CdS is yellow and HgS is black.
