This is Ice.
Ice did not become more affordable until the mid-19th century, when some significant breakthroughs in refrigeration occurred. Frederic Tudor - the Boston entrepreneur known as the “Ice King" and Nathaniel Wyeth built an #ice shipping business from the ground. Their company invented horse - drawn ice cutter to replace the laborious process of harvesting ice with chisels and saws, and enabled mass production. These giant ice cubes, could be packed more tightly to minimize melting and lowering the price of ice. As the cost of ice fell, ice houses started to pop up all over the world. Insulated carriages and refrigerated box cars for trains emerged, allowing the ice to be transported further with less loss... ----------------
Nearing the halfway point of the 19th century, frozen lakes were no longer the only means to produce blocks of ice. In Mississippi, Dr. John Gorrie invented the first ice-making machine in 1845. Much like Frederick Tudor a few decades before, no one took the idea seriously. John even made a successful prototype to show off what his invention could achieve, but to no avail. He was not able to fund the idea, and so the ice maker concept sat on the shelf for several decades.
Andrew Mulh to help the beef industry in #texas , picked up the idea and developed the first commercial ice machine in 1867.
