No indications of bleaching or dyeing were evident, which was confirmed by microscopic observation and Fourier-transform infrared (FTIR) spectroscopy. In the near-colourless areas, many small white shiny flecks (sometimes known as 'fly wings') were visible, even to the unaided eye, which were produced by reflections from mineral cleavages.
