A Victorian machine for making ice Metal ice moulds from the early ice factories. They are about 4 feet high and 2 feet long (1.3 m, 0.7 m)
The first picture shows a Victorian machine for making ice from water in London. This is a type that used a chemical, ether, as part of the ice making process and it was powered by a steam engine. Later, different processes were invented and more efficient machines were used. The second picture shows two ice moulds which were used to make ice in a London factory. The moulds were placed in a tank of salt water. The salt water was cooled to lower than the freezing point of water and the water in the moulds froze.
