Chemical retort, earthenware, English(?), 1801-1930

Retorts have long been standard pieces of laboratory equipment. They are used during chemical experiments and large-scale processes such as distillation. Normally made of glass, this example is made from earthenware and is a typical shape, with a long stem and a large bowl. Reagents are placed in the bowl and heated from underneath. It is shown with a similar example (A634003).
