N2 - The combined techniques of scanning electron microscopy, energy dispersive X-ray analysis, transmission electron microscopy (TEM) and selected area electron diffraction are used to characterise the microstructures of opaque coloured glass mosaics from a mediaeval church in Torcello, Italy. Comparison of MgO/K2O ratios allows distinction between mediaeval and modern glass artefacts to be made. TEM investigation of inclusions indicates that relict silica is responsible for the speckled appearance of an impure mediaeval glass artefact, whilst a fine scale dispersion of elemental Cu nanoparticles is considered responsible for the orange-red colouration of a modern glass artefact.
