@davej "The pigment has received considerable attention because of its peculiar nature as an organic-inorganic hybrid material, its characteristic palette, ranging from a bright turquoise to a dark greenish blue, and its enormous resistance to attack from acids, alkalis, organic reagents and biodeterioration.

"Research paused during World War II, and it was not until the 1950s that powder diffraction analysis revealed the Maya blue pigment had been made by mixing clay, palygorskite (a rare fibrous clay) and indigo. "
