Natural Earth Pigment Properties

Natural Earth & Mineral Pigments are beautifully archival, eco-friendly, and sustainably-harvested from around the world. They contain no added fillers, additives, preservatives, stabilizers, or heavy metals.


Each natural pigment has a different set of characteristics, such as liquid absorption, volume, tinting strength, and granulation. Because of these characteristics, they each require a different volume of binder to create the desired paint consistency.

Throughout history, blues in nature were very rare and usually made with precious stones like Lapis Lazuli. These stones are now unsustainably harvested in Afghanistan, so we have found this beautiful, non-toxic and sustainably- made alternative from France.
