1500-year-old Mayan paint job peeled back
MORE secrets of the Mayan civilisation are being revealed via groundbreaking research into paint pigments used on a temple at one of the culture's most significant sites: Copan, in Honduras.

Brisbane physical and chemical sciences PhD student Rosemary Goodall used an infrared analysis technique, FTIR-ATR spectral imaging, never before applied in archeology.

It revealed a map of the painted surfaces of stucco masks that adorn the corners of the Rosalila temple, built in about AD550.

Mrs Goodall found that the Mayans mixed finely ground muscovite mica in their paint, which would have made parts of the building glitter in the sun.
