Most tattoo inks
technically not ink. They are suspended by mixing in a reactive dye solution formed. In contrast with ordinary knowledge, these pigments are not vegetable dyes. Below I've listed several major tattoo ink color and the formation of chemical elements required for this color.
Material: iron oxide (Fe3O4), an iron oxide (FeO), carbon, logwood
Note: The natural melanin by magnetite crystals, powder, ferrite, bone charcoal burning bituminous coal amorphous carbon material. Melanin is generally considered to be formed by the ink.
Logwood (ink tree) of the core material is black, can be used to prepare the dye, produced in Central America and the West Indies.
Note: a mixture of iron ocher clay. Ocher yellow line of the original stone, heated dehydration ore red.
Material: cinnabar (HgS) cadmium red (CdSe) iron oxide (Fe2O3) Naphthol AS
Note: iron oxide, commonly known as rust, cinnabar and highly toxic cadmium, naphthol red is synthesized by naphtha. Compared with other pigments, naphthol red is rarely mentioned, but all of the red pigment are more prone to side effects.
Material: cadmium selenium sulphide
NOTE: This organics were concentrated by two dye molecule, together, macromolecules with fixed heat release, and will not fade.
Material: ocher (a mixture of iron oxide and clay)
Material: cadmium yellow (CdS, CdZnS) chrome yellow ocher turmeric (PbCrO4, usually mixed PbS)
Note: turmeric ginger family, turmeric genus. Often the reaction of yellow pigment, the pigment part of the need to add more to bring up a more bright yellow.
Material: chromium oxide (Cr2O3) malachite [Cu2 (CO3) (OH) 2] lead chromate pigment dye
Notes: Green is mainly composed of potassium ferrocyanide (yellow or red) and purple blue ferric ferrocyanide (Prussian Blue) blend.
Color: blue, sky blue, cobalt blue
Material: Copper - phthalocyanine dye
Note: The blue mineral used primarily copper carbonate (azurite), lapis lazuli, silicon calcium copper (Egyptian blue), as well as aluminum oxide and chromium oxide, cobalt oxide. Safest blue and green pigments are copper salts made, such as copper phthalocyanine. Copper phthalocyanine is approved by the US Food and Drug Administration for baby furniture and toys. Copper-based pigments are generally more stable and secure than cobalt and aluminum.
