Description
An insoluble, dry solid that is pulverized to a fine powder then mixed with a binder to form a Paint, Ink, or Crayon. Pigments can provide both Color and Opacity. The type and composition of pigments has changed significantly over the years. Originating as materials pulverized from minerals, modern pigments are now synthetically processed to ensure purity. Pigments discontinued due to toxicity include most containing Arsenic, Chromium, and Lead. Titanium, used in Titanium white pigment as a 20th century replacement for Lead white, was listed as possibly carcinogenic in 2006.
Examples of inorganic pigments:
- earth colors (Ocher, Sienna, Umber, Green earth);
- metallic oxides (Ferric oxide, Titanium dioxide, Zinc white; Viridian);
- metallic carbonates (Lead white, Calcite, Malachite);
- metallic chromates (Lead chromate; Barium chromate)
- carbon black (Bone black, Lampblack, Graphite)
Examples of some organic pigments are:
- animal (melanin, Cochineal, Indian yellow)
- vegetable (Madder, Indigo, Gamboge)
- synthetic (Verdigris, phthalocyanines, lakes, Para red)
