Sepiolite is a lightweight, absorbent clay from the Yucatan region used in making the historic pigment Maya Blue. When heated with botanical indigo powder, the sepiolite absorbs sublimated indigo blue, forming a very stable and lightfast turquoise blue pigment. Sepiolite is hydrated magnesium silicate.

For the most uniform pigment color, sepiolite granules may be finely pulverized in a mortar and pestle prior to heating. Wear a dust mask when grinding pigments. Sepiolite is very absorbent; always store it in an airtight container.
