History of Stoneware Mercury Jug

These stoneware jugs were commonly used in the late 19th and early 20th centuries for storing and transporting various liquids, including chemicals like mercury. The durable nature of stoneware made it ideal for such purposes, as it was less prone to breakage than glass and provided a stable environment for its contents. Jugs marked 'MERCURY' were specifically used by apothecaries, dentists, and other medical professionals for the safe handling of elemental mercury.
