Bowl. Rome, 1st century BC. Mould-made glass. With beautiful iridescence. In a good state of preservation. Provenance: private collection. Certificate issued in 1980 is attached. Measurements: 3 x 9.8 cm (diameter). Bowl intended to contain cosmetic creams or ointments. This is a piece of feminine toilet that later formed part of a funerary or burial trousseau. The use of glass began to become widespread from the 1st century AD, following the discovery of the blowing technique around 40 BC, in the eastern part of the Mediterranean coast. This technique was a major revolution and spread rapidly. Blown glass offered great advantages over other materials because it did not change the taste of the food it contained and was more impermeable than terracotta. In addition, the blowing technique made it possible to produce pieces in a wide variety of shapes and sizes, and also to produce them more quickly. On the other hand, glass pieces were easier to clean, so it soon became the favourite material for domestic use.
