Before the invention of refrigerators
Before the invention of refrigerators, ice was transported in quite ingenious ways. Large blocks of ice were cut from frozen lakes and stored in straw-lined pits, then covered with earth to keep out the sun's heat. For transport, they used horse-drawn carriages, trains, and boats with insulated holds to keep the ice cold during transit. The larger the ice blocks, the smaller the surface area exposed to the air and the slower they melted. Additionally, materials like straw served as extra insulation. These techniques allowed ice to be transported over long distances without completely melting.
