Ca. 100-300 AD.A group of five glass flasks consists of a collection of exquisitely crafted glass vessels, each with its unique shape and purpose. These flasks were specifically designed to store perfumed oil, commonly known as unguentum. Within this group, we find flasks with globular, piriform, and cylindrical forms, each serving its own function within the ancient Roman society. Roman glass production was renowned for its innovation and sophistication. The glassmakers of the time employed various techniques and materials to create these delicate and aesthetically pleasing flasks. The process typically involved heating a mixture of silica, soda, and lime, resulting in the creation of a molten glass that could be molded and shaped into the desired form. Glassblowing, a technique perfected by the Romans, enabled the artisans to manipulate the molten glass with precision and intricacy, allowing for the production of vessels with intricate details and elegant shapes.
