Mineral-laden earths are the world’s oldest known art materials, first used on cave walls and rocks around 400,000 years ago.
These strong, non-toxic, permanent pigments are compatible with most mediums.
Earth colors are not consistent, even from the same mine, so each order of the same color may be a slightly different shade. Differences in color are due to how hydrated the earth was when it was mined, or if the earth was heated, or how light is diffracted through the particle size of the oxide.
