Two perfumery jars. Rome, 1st century AD. Blown glass with beautiful iridescence. In excellent condition. Old collection label. Certificate issued in 1981 enclosed. Measurements: 6.6 x 6 cm and 7.5 x 5.5 cm. These two globular perfume bottles have short necks and wide mouths. Both pieces have irregularities on their surface to make them stick better in the hand. They are female toilet articles and may have been part of a funerary trousseau. The use of glass began to become widespread from the 1st century AD, after 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.
