Ca. 100-200 AD. Roman. A black, blue, and orange blown glass unguentarium with a globular body, a short cylindrical neck, and a folded rim. Excellent condition. Unguentaria, like alabastra in ancient Greece, were small jars used to store perfume or toilet oil in the Roman period. While glass-making had been practised for centuries, the Romans invented the glassblowing technique in the 1st century BC, which revolutionized this craft. Roman glassmakers reached incredible artistic heights with both free-blown vessels and mould blown forms and decorations.
