Roman Glass Unguentaria

The Roman Empire, c. 100-200AD.

This exquisite Roman glass bottle, known as an unguentaria (also called unguentarium, balsamarium, or lacrimarium), was likely used for storing oils, lotions, or other liquids and powders. The bottle features a narrow, long neck, a bell-shaped body, a constricted neck at the junction of its flat base, and an everted rim with an in-folded lip. Its excellent, intact condition highlights a form that was widely used across the Roman Empire from the late first century through the early fourth century.

Unguentaria were often found in Roman burials, though the exact purpose of their inclusion in grave goods remains uncertain. These bottles could have been used to hold substances such as oils, wine, or incense, possibly for use in funerary rituals or as offerings to the gods.

Roman glassmakers were pioneers in the craft, advancing glass technology over 2,000 years ago. They developed soda-lime glass, made from a mixture of silicon, sodium, and calcium oxides, and often added colorants to achieve vibrant hues. Copper was used to produce colors ranging from turquoise to light blue, green, and red. Cobalt created a rich blue, while manganese and antimony were used for yellow, white, and purple shades. Iron was used to create light blue, green, brown, and black colors, often chosen to mimic the appearance of precious gemstones like lapis lazuli, amethyst, and turquoise. This unguentarium is a remarkable example of Roman glassmaking, showcasing the ingenuity and artistry of ancient craftsmen
