Roman Glass Unguentaria

The Roman Empire, c. 100-200AD.

This striking Roman glass bottle, known as an unguentaria (alternatively called unguentarium, balsamarium, or lacrimarium), was most likely used for storing oils, lotions, and other liquids or powders. Its design features a gracefully tapering neck, a bell-shaped body, and a slightly constricted neck at the junction of a flat base, finished with an everted rim and an in-folded lip. The bottle is remarkably well-preserved, offering a glimpse into the popular form that spread throughout the Roman Empire from the late first century to the early fourth century.

Unguentaria were commonly included in Roman tombs, though their precise function in burial practices is not fully understood. It is believed that they were used to contain oils, perfumes, or incense, and may have played a role in funeral rituals or served as offerings for the afterlife.

Roman glassmaking advanced significantly over 2,000 years ago, with artisans perfecting the technique of soda-lime glass. This glass was created by blending silicon, sodium, and calcium oxides, and colorants were often added to produce a range of vibrant hues. Copper created turquoise, light blue, green, and red shades, while cobalt was used for a rich, deep blue. Manganese and antimony were responsible for the creation of yellow, white, and purple tones, and iron added colors ranging from light blue to brown, green, and black. Many of these colors were inspired by precious gemstones, such as lapis lazuli, amethyst, and turquoise.

This beautifully crafted unguentarium serves as an exquisite example of Roman craftsmanship, illustrating the advanced glass-making techniques and aesthetic values of the time.
