How Did Old Fashioned Ice Boxes Work?
Old fashioned ice boxes worked by using blocks of ice to keep food and drinks cold. The ice was placed in a compartment at the top of the box and cool air from the ice would circulate downward into the main compartment where food was stored. As the ice melted, it would drain into a tray at the bottom of the box and needed to be replaced regularly. The insulation of the ice box helped to keep the cold air inside, and the door was often made of wood or another material that helped to maintain the interior temperature.
