Zinc sulfate sulphate lithopone making mordant 1 lb
Zinc sulfate (ZnSO4) is a colorless crystalline, water-soluble chemical compound. The hydrated form, ZnSO4 7H2O, the mineral goslarite, was historically known as "white vitriol" and can be prepared by reacting zinc with aqueous sulfuric acid. It may also be prepared by adding solid zinc to a copper(II) sulfate solution.
It is used to supply zinc in animal feeds, fertilizers, and agricultural sprays. ZnSO4 7H2O is used in making lithopone, in coagulation baths for rayon, in electrolytes for zinc plating, as a mordant in dyeing, as a preservative for skins and leather and in medicine as an astringent and emetic.

Another natural form of this heptahydrate is known as mineral Zinc-melanterite (Zn,Cu,Fe)SO4 7H2O (structurally different from goslarite). Lower hydrates of zinc sulfate are rarely found in nature as minerals: bianchite (Zn,Fe)SO4 6H2O, boyleite (Zn,Mg)SO4 4H2O and gunningite4 H2O. (Zn,Mn)SO
An aqueous solution of zinc sulfate is claimed to be effective at removing moss from roofs. Spraying a mixture on moss will allow the wind to simply blow off the remaining debris, however it is not recommended for use on lawns as it is as effective at removing grass. [4] Zinc sulfate was once used in home acne remedies.
