Rosemary Goodall, a Brisbane physical and chemical sciences PhD student, used infrared analysis technique, FTIR-ATR spectral imaging, to analyze the painted surfaces of the 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 [The Australian: Higher Education, Jill Rowbotham, January 23, 2008].
