Abstract:
The Silk Road connected the east of Iran to the western world. Roue city is close to the
Road. Six glass samples from Roue were classified on the basis of morphology, archaeological context
and compositions. The samples were analysed by means of XRF and Raman spectroscopy and
two specific groups, namely Roue type 1 and Roue type 2, with close composition to high alumina
plant-ash glass in circulation from the 6th to 10th centuries CE in Mesopotamia, Iran and Syria, were
identified. The simultaneous occurrence of two types of glass in the excavated layers shows that the
house was inhabited in the early Islamic period. Colours (black, amber-green, light and aqua blue)
were produced mainly by the amount of iron and sulphur ions required for the amber chromophore
and copper ions for the blue colour and the controlling of reducing conditions in the furnace.
