Upon thermal treatment between 100 and 180 °C, significant isomerization and oxidation reactions occur thus resulting in the formation of polyfunctional materials potentially usable for therapeutic, catalytic and art purposes. The dye attachment to the clays would define a 'Maya chemistry' whose complexity could explain the versatile use of such materials in the pre-Columbian cultures.
