Ca. 100-300 AD. A finely blown ampulla flask of aqua-coloured glass. The vessel features a flat, spherical body, a long cylindrical neck slightly constricted at the base. While glass-making had been practiced for centuries, the Romans invented the glassblowing technique in the 1st century BC, which revolutionised this craft. Roman glassmakers reached incredible artistic heights with both free-blown vessels and mould-blown forms and decorations.Size: L:55mm / W:35mm ; 10gProvenance: Private UK collection; From an old British collection formed in the 1990s.
