Deals with a unique glass bead from Wilsford, Wiltshire in southern England. The date of the bead is probably Wessex II; ca. 1400-1200 BC. It was first recognized as being glass in print in 1812, but until recently has been considered as being of stone rather than glass in line with its original description. Here the bead is described, together with surface scanning electron microscopy (SEM) studies, the replication work on glass of similar composition reported, and its unusual chemical composition discussed in terms of its durability and comparable Bronze Age glass compositions. -- AATA
