Short History of Black Pigments. Carbon black was the first black. This dull black is the easiest to manufacture because it is made of charcoal. Another black is vine black, which is traditionally made by charring desiccated grape vines and stems, which produce beautiful bluish blacks. Bone black, made of burnt bones from prehistoric times, is the deepest available black.
All our pigments are environmentally safe and non-toxic and are used in fine art, crafting, home decorating and various architectural uses. Our Natural Earth and Ocher pigments are rich colors including Ochers, Siennas, Umbers and natural oxides with a depth of color unmatched by synthetic mass-produced pigments. French Mineral Pigments are a beautiful palette that reflects the colors of the French Countryside.
