Beehivekjeler

Beehivekjeler, or beehive kettles, is a term used in Norwegian technical literature to describe a class of kettle-like vessels with a domed, beehive-shaped body used for boiling liquids in traditional industrial processes. Constructed from copper, cast iron, or brass, the vessels typically consist of a rounded upper section seated on a short cylindrical or tapering base, with a firebox or bottom opening to provide heat. Some designs include a side tube for steam venting and a tap for draining liquid.

Historically, beehivekjeler appeared in Scandinavia and northern Europe from the 18th to the 19th century, used in distilleries, sugar works, soap and lye boiling, and textile dyeing. The shape is associated with efficient heat distribution and reduced scorching on the kettle walls, though effective operation required careful temperature control and steady fuel management.

In use, the kettle was placed over a direct fire or a heated stove. Temperature was controlled by adjusting the air supply and, in some designs, by varying the kettle’s position relative to the flame. Maintenance included regular cleaning, descaling, and checking joints for leaks.

Today, surviving examples are found in museum collections and in some regional craft settings, illustrating traditional metalworking and industrial practices. Beehivekjeler are often discussed in the context of pre-industrial heating vessels and related to other beehive-shaped vessels such as lime kilns or copper cookery.
