Ca. 100-200 ADA free-blown glass flask of a conical-shaped body, concave base with a pontil mark, tubular neck with everted rim. By the 1st century AD, the technique of glass-blowing had revolutionised the art of glass-making, allowing for the production of small medicine, incense, and perfume containers in new forms. These glass vessels are found frequently at Hellenistic and Roman sites, and the liquids which filled them (perfumes, oils, medicines) would have been gathered from all corners of the expansive Roman Empire.
