Roman Glass Unguentaria

The Roman Empire, c. 100-200AD.

This impressive Roman glass bottle, known as an unguentaria (also referred to as unguentarium, balsamarium, or lacrimarium), was likely used to store oils, lotions, and other liquid or powdered substances. Characterized by a narrow, long neck, this unguentarium features a bell-shaped body, a tubular neck with a slight constriction at the junction of its flat base, and an everted rim with an in-folded lip. The bottle is in excellent, intact condition, showcasing the form widely popular across the Roman Empire from the end of the first century through the early fourth century. Unguentaria were common in Roman burials, although their precise purpose in grave goods remains uncertain. While often buried with the deceased, these bottles may have held oil, wine, or incense for funerary rituals or as offerings to the gods.

Roman glassmakers were pioneers in advancing glass technology over 2,000 years ago, transforming glass production into both an art and a science. Made from soda-lime glass, which included silicon, sodium, and calcium oxides, Roman glass often incorporated various colorants to create beautiful hues. Copper was used to produce colors ranging from turquoise to light blue, green, and red. Cobalt achieved a rich, deep blue, while manganese and antimony were used to make vibrant yellows, whites, and purples. Iron created colors such as light blue, green, brown, and black, often chosen to imitate the shades of precious gemstones like lapis lazuli, amethyst, and turquoise.

This beautifully preserved unguentarium bottle exemplifies the skill and sophistication of Roman glassmaking, a true testament to their innovation and artistry.
