history of Refrigerators
The first refrigerators were made...
At the start of the 19th century in England. Before fridges, people salted and smoked meat or stored food in cellars. They also did things like store ice underground or set them in cold streams.
Refrigerators began as wooden boxes lined with zinc or tin then they would put blocks of ice covered in cork, sawdust, or seaweed to hold them. The ice eventually melted and had to be replaced often. A man named Michael Fraday did an experiment that liquefied ammonia to cool things and that's how most refrigerators today work but changed a bit. The introduction to in-home refrigerators came in the early 1900's. Then it progressed from there into the amazing refrigerators we have today.
