Zinc white is a very light, finely dispersed powder of dazzling white color with a faint bluish tinge. Obtained by oxidation of zinc vapor in a stream of air. In the light, this whitewash is resistant, however, under the influence of air, it absorbs water and carbon dioxide from it and transforms into crystalline, basic carbon dioxide, which has a lower covering power than ZnO . Therefore, you should store powder white in a well-closed container. Zinc white does not turn black in the presence of hydrogen sulfide, since the resulting zinc sulfide is not black (like lead white), but white.
