Pole ice
Rod ice (also block ice or raw ice ) refers to water ice that is not intended for consumption . Block ice can be produced in an ice factory or come directly from frozen waters ( natural ice ). During the ice harvest, larger blocks were sawed out from an ice thickness of ten centimeters, which were then cut into easily transportable pieces. These were transported to the user by an ice cream man after they were possibly stored in an ice cellar . The typical temperature of this ice ranged from −20 ° C to −1 ° C to be sufficient for cooling food and beverages. Pole ice from ice factories was or is produced in various sizes. In the household, ice was often used in a refrigerator , the forerunner of the refrigerator .
The technical development of gas and electricity-driven cooling units largely replaced this type of cooling technology . Initially, artificially produced ice bars were delivered to consumers until electrically operated refrigerators found their way into households. Today ice cream is mostly only used for decorative reasons.
