Please note this is a raw pigment intended to be dispersed into a liquid medium to make paints. Our raw pigments are not meant for use in cosmetics and are not cosmetic grade. Certain pigments disperse more easily than others in certain liquid mediums. For those difficult to disperse into a liquid of your choice, they will need to be ground by a muller or a mortar and pestle into the medium.
Safety note: Handle all dry pigments with care. Work slowly to avoid generating airborne dust and wear a dust mask for extra protection. Also avoid getting the dust all over your hands. Latex gloves are good at providing skin protection without "getting in the way".
Ferrous Sulfate Heptahydrate is the most common form of Iron (II) Sulphate. It's been known since antiquity as Copperas or Green Vitriol. It's water soluble and has been used in solutions for a variety of things since ancient times. Some practical uses today in arts and crafts include staining concrete & limestone a yellow/rust color, staining maple wood a silvery color, and staining leather black. It can also be used to make inks and used as a mordant in wool dyeing.
Centuries ago when chemists were known as alchemists, this was called green vitriol. We also carry a material known then as blue vitriol (see the link above). The connection of "vitriol" is interesting and there's a short article on it at Wiki:
https://en.wikipedia.org/wiki/Vitriol :
"Vitriol is an archaic name for a sulfate, and vitriol names have the obvious meaning: for example, vitriol of lead is lead sulfate, and so on. The word vitriol comes from the Latin word "vitriolum" for "glassy", as crystals of several metallic sulfates resemble pieces of colored glass. Vitriol with no further qualification often means sulfuric acid."
There's a snazy alchemical diagram in that article and a listing of 14 types of "Vitriol".
The Wiki article on Ferrous Sulfate Heptahydrate is here:
https://en.wikipedia.org/wiki/Iron(II)_sulfate
"Industrially, ferrous sulfate is mainly used as a precursor to other iron compounds....
Historically ferrous sulfate was used in the textile industry for centuries as a dye fixative. It is [also] used...to blacken leather and as a constituent of ink...
Ferrous sulfate was used in the manufacture of inks, most notably "iron gall ink" [ Interesting article on that ink here: https://en.wikipedia.org/wiki/Iron_gall_ink ], which was used from the middle ages until the end of the eighteenth century...
It also finds use in wool dyeing as a mordant. Harewood [ https://en.wikipedia.org/wiki/Harewood_(material) ], a material used in marquetry and parquetry since the 17th century, is also made using ferrous sulfate...
Two different methods for the direct application of indigo dye were developed in England in the eighteenth century and remained in use well into the nineteenth century. One of these, known as china blue, involved iron(II) sulfate. After printing an insoluble form of indigo onto the fabric, the indigo was reduced to leuco-indigo in a sequence of baths of ferrous sulfate (with reoxidation to indigo in air between immersions). The china blue process could make sharp designs, but it could not produce the dark hues of other methods. Sometimes, it is included in canned black olives as an artificial colorant.
Ferrous sulfate can also be used to stain concrete and some limestones and sandstones a yellowish rust color.
Woodworkers use ferrous sulfate solutions to color maple wood a silvery hue...
Other uses: horticulture [lawn conditioner, moss killer]...photographic developer for collodion processed images...gold refining...purification of water...wood treatment and component of paints...as a reagent in the identification of mushrooms."-
