Eli5: How did people make and keep ice in medieval times, and how do we manufacture ice cubes now ?
In: Technology
In old times people would cut big ice blocks in winter from rivers, lakes etc. Then store them in storage buildings, away from sources of heat or warmth. The bigger the block is the longer it takes for it to melt. Additional insulation would also be used to keep it cold for longer. They would prepare it every winter and sustain on it throughout the year until next winter.
Quite a few older cities have remains of ice storage warehouses as it was widely used in industries.
