In a 19th-century pharmacy or medical museum, this allowed bladder skins, oiled cloths, or large organic corks to be tied tightly over the lip to secure dry chemicals or biological specimens.\u003c\/p\u003e\n\u003cp\u003eHeight: 18.7 cm\u003cbr\u003eWeight: A remarkably heavy and robust 422 grams (reflecting high lead content)\u003cbr\u003eBase Foot Diameter: 6.3 cm (flared for a stable, low center of gravity)\u003cbr\u003eMouth Rim Diameter: 4.9 cm\u003cbr\u003eBody Tube Circumference: 19.2 cm (approx. 6.11 cm diameter)\u003c\/p\u003e\n\u003cp\u003eExcellent antique condition with wonderful clarity.
