Roman Glass Unguentaria

The Roman Empire, c. 100-200AD.

This exquisite Roman glass bottle, known as an unguentaria (or unguentarium, balsamarium, and lacrimarium), was likely used for holding oils, perfumes, or other liquid and powdered substances. The bottle features a slender, elongated neck that flows into a bell-shaped body, with a slight constriction at the neck’s junction to the flat base. The everted rim is delicately folded inward, and the bottle remains intact, displaying a form that was widely adopted throughout the Roman Empire from the first to the early fourth centuries.

Unguentaria were frequently found among Roman grave goods, though their exact purpose in funerary contexts is still debated. These bottles may have been used in rituals or as offerings, potentially containing oils, wine, or incense to honor the deceased or gods.

Roman glassmakers were pioneers of advanced techniques over two millennia ago, with the development of soda-lime glass. This glass, made from silicon, sodium, and calcium oxides, was often colored with various metallic oxides. Copper provided shades from turquoise to light blue, green, and red, while cobalt was used to create a striking deep blue. Manganese and antimony produced vibrant yellows, whites, and purples, and iron contributed colors ranging from light blue to brown, green, and black, often mimicking the hues of precious gemstones like lapis lazuli and amethyst.

This unguentarium is a testament to the sophistication of Roman glassmaking, offering a glimpse into the artistry and innovation of the ancient world.
