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".
This is a synthetic version of the colorants found in the minerals azurite and malachite. The blue-green compound is properly called 'Basic Copper Carbonate' or 'Copper(II) Carbonate Hydroxide'. It has the formula Cu2CO3(OH)2. It's been used for centuries as a paint pigment, but is also used in ceramic glazes as a pigment. This is not CuCO3, "copper(II) carbonate" proper, (neutral copper carbonate) [which] is a rarely seen moisture-sensitive compound" [Wiki].
This site: https://www.highettmetal.com.au/blog/copper/what-is-copper-carbonate-used-for says: "This substance, when pure, should have a mint green color. When alkaline components have been added, a tinge of blue will be added to the color. This is often added to paints, varnishes, pottery glazes and even fireworks to impart some of the color."
The ceramics database, DigitalFire, https://digitalfire.com/4sight/material/copper_carbonate_basic_236.html says when this is used in glazes:
"This form of copper carbonate is the article of commerce. What you are getting when you buy it is a mixture of theoretical copper carbonate and copper hydroxide.....Supplies of green copper carbonate basic often vary in color and density (darker and heavier, lighter and fluffier) reflecting variations in raw materials and manufacturing procedures. Despite variations in the physical appearance of the material, the amount of contained copper metal remains essentially constant."
The Wiki article on "Basic Copper Carbonate" is here:
https://en.wikipedia.org/wiki/Basic_copper_carbonate
"The basic copper carbonates, malachite and azurite, both decompose forming CO2 and CuO, cupric oxide. The purer, malachite pigment version is called "verditer", "green bice", or "mountain green", when occuring as azurite the pigment is called "blue verditer" or "mountain blue.....'Copper carbonate' was the first compound to be broken down into several, separate elements (copper, carbon, and oxygen). It was broken down in 1794 by the French chemist Joseph Louis Proust (1754–1826). When heated, it thermally decomposes to form CO2 and CuO, cupric oxide, a black solid. The basic copper carbonates, malachite and azurite, both decompose forming CO2 and CuO, cupric oxide."
