	Iron(II) sulfate - Wikipedia, the free encyclopedia
		Iron(II) sulfate has a blue-green color, monoclinic crystal structure, and is water-soluble.
		Iron(II) sulfate is prepared commercially by oxidation of pyrite or by treating iron with sulfuric acid.

	The ink corrosion website: iron gall ink: ink recipes
		In early recipes, iron sulfate and copper sulfate were used interchangeably, in part because natural sources of the minerals were usually mined together.
		As iron sulfate became available through chemical suppliers, some recipes suggested cooking in a copper pot or otherwise adding copper salt to the mixture, presumably based on the belief that copper sulfate reacted with iron sulfate to produce color.
		Pure iron sulfate may be obtained from chemical, specialty art or fabric dye suppliers in the form of a pale green powder or granules.

		The available thermodynamic data for the ferrous sulfate hydrates are sufficient to develop a model for the contribution of each H2O molecule to the Gibbs energy of formation in nearly the same detail used in the enthalpy of formation calculations.
		Mixed ferrous and ferric sulfates There are few thermodynamic data for mixed ferrous and ferric compounds so the model used to estimate the thermodynamic data for this type of phase is similar to that used for halotrichite.
		The mixed iron sulfate hydrate phases are assumed to have slightly larger (about 0.3 percent) enthalpies of formation than the summation of values for the ferrous and ferric sulfate hydrates.
