What is Sasanian glass?

Sasanian Glass is the glassware produced between the 3rd and the 7th centuries AD within the limits of the Sasanian Empire of Persia, namely present-day Northern Iraq , Iran and Central Asia. This is a silica-soda-lime glass production characterized by thick glass-blown vessels relatively sober in decoration, avoiding plain colours in favour of transparency and with vessels worked in one piece without over- elaborate amendments. Thus the decoration usually consists of solid and visual motifs from the mould , with ribbed and deeply cut facets, although other techniques like trailing and applied motifs were practised.
