Washington, April 21 : In a new research, scientists have determined that the ancient Maya civilization used a rare type of clay called "palygorskite" to produce Maya blue, a unique bright blue to greenish-blue pigment.
As part of the research, the Spanish research team defined the features of palygorskite clay on the Yucatan Peninsula in Mexico.
These findings will make it possible to ascertain the origin of the materials used to produce this pigment, which survives both time and chemical and environmental elements.
The team traced the route followed by the Maya to obtain palygorskite clay, one of the basic ingredients of Maya Blue.
