Enamelled Measure Jar This is an enamelled measuring jar with a capacity of 20 ounces, as stamped in black ink on one side. It features a cylindrical shape with a spout and handle, made of metal coated in white enamel, with the rim and spout decorated in blue. Inside the jar, there is a black ink scale ranging from 2 to 20 ounces. Only a few signs of wear and tear are visible. This type of jar was commonly used in medical settings for measuring and dispensing liquids, such as medications or solutions, due to its durability and ease of cleaning. The enamel coating helps prevent contamination and makes it suitable for repeated use in clinical environments. 1900-1949
