Maya blue: its presence in cuban colonial wall paintings

Abstract

AbstractAbstractA blue pigment frequently found in Cuban colonial decorative wall paintings from about 1750 to 1860 has been identified with the aid of thin-layer chromatography, IR spectrometry, X-ray diffraction, thermal analysis, scanning electron microscopy and X-ray microanalysis as ‘Maya blue’. This is the first reported occurrence of Maya blue from a period after the conquest and in a non-Mayan cultural area.
