Today’s Day 138 VM 365 image shows our largest fragment of Roman window glass from the villa at Minster dating to around the 1st to 2nd century.
This fragment of clear glass is a pale olive brown, growing pinkish in colour toward the broken edge. You can see many tiny air bubbles throughout the fragment. The glass appears to have been poured as a single sheet into a mould, onto a flat, slightly rough surface, possibly compacted sand, as the underside is also slightly rough in texture. The upper side is shiny and wavy rather like the surface of poured toffee and is thicker along the rounded edge which would have been formed against the edge of the mould.
