Amphoriskoi are delicate small flasks with two handles used primarily to store oil and expensive perfume. They were small in size, made to fit comfortably in one’s hand. They differed slightly in their style to unguentaria which had a more practical purpose rather than decorative.
Glass production evolved during the Roman Empire with the introduction of glassblowing which allowed for a great variety of different shapes and styles to be constructed. The technique allowed for easier manipulation of the glass into more intricate designs with an assortment of functions. Glassblowing also allowed for a quicker paced production, the hot glass would be blown into a mould and then removed whilst still hot so that the glass maker could still work on it. Different minerals were added to create a variety of colours; the blue tint seen in this piece would have been created by adding cobalt oxide and copper oxide.
