How to Make ice in Ancient Times It Is really Surprising
They didn't. Until the invention of the refrigeration cycle, all ice was a result of natural freezing. Ancient people's had basically two options, if they wanted ice in hot weather. If they lived near mountains that had snow on top, they could have ice and snow carted down, or they could try to store ice during the winter in such a way that it wouldn't all melt before the weather warmed up. Ice houses, generally insulated with straw, have been around in one form or another for a long time.
In the early 19th century, an American entrepreneur worked out a way to cut ice out of frozen lakes, pack it in sawdust to insulate it, and ship it across the country (and eventually across the world. Unfortunately for him, it was a pretty easy process for competitors to copy, which means that he didn't really become rich, even though the process became widespread. That became the primary way of providing ice to much of the world, until mechanical freezers were invented
