The first direct evidence for the production of Maya Blue: rediscovery of a technology

Maya Blue is a colour that is more than a pigment; it had roles in status, ritual and performance, being daubed onto pots and people before sacrifice. Here researchers use experimental and historical evidence to discover how it was made, including direct scientific analysis of Maya Blue on a pot thrown into the sacred well at Chichen Itza. The results indicate that the formation of the colour was actually part of the ritual.
