Glass bottles, such as this beautiful example, were used as containers for ointments, powders, balms, and other expensive liquids associated with the toilet, especially perfumes. The small mouth of the bottle is ideal for slow, careful pouring, while glass was preferred for holding liquids, due to its non-porous, non-absorbent nature. Glass vessels are found frequently at Hellenistic, Roman and Levantine sites, and the liquids that filled them would have been gathered from all corners of the expansive Roman Empire.
