icebox
An icebox (also called a cold closet) is a compact non-mechanical refrigerator which was a common kitchen appliance before the development of safe powered refrigeration devices.
== Design ==
Iceboxes had hollow walls that were lined with tin or zinc and packed with various insulating materials such as cork, sawdust, straw or seaweed. A large block of ice was held in a tray or compartment near the top of the box. Cold air circulated down and around storage compartments in the lower section. Some finer models had spigots for draining ice water from a catch pan or holding tank. In cheaper models a drip pan was placed under the box and had to be emptied at least daily. The user had to replenish the melted ice, normally by obtaining new ice from an iceman.
Commonly iceboxes were made of wood, most probably for ease of construction, insulation, and aesthetics; many were handsome pieces of furniture.
