Description
A greenish-blue pigment found on wall paintings and painted objects from several Maya sites. After many years of study, it was determined in 1967 that Maya blue is composed of Indigo absorbed on a clay substrate (Kleber et al., 1967). Palygorskite (Attapulgite), Montmorillonite and Sepiolite clays were used (Torres 1988).
Synonyms and Related Terms
Mayan blue (sp); bleu maya (Fr.); Mayablau (Deut.); azul maya (Esp.); azul de Maya (Esp., Mex.); mple ton Magia (Gr.); blu Maya (It.); Maya blauw (Ned.); azul Maia (Port.)
Possible synonyms: Canutillow blue; Tekax blue; texotli (Mex.)
Risks
No significant hazards.
