Refrigerators were made for the home starting in 1913, so they were still a very new tech by the 20s. They usually were more expensive than a Model-T Ford. The first refridgerator to see widespread use was the GE &quot;Monitor-Top&quot; Refridgerator, named so because the top looked like the gun turret of the USS Monitor of the 1860s. The introduction of Freon in the 1920s also provided a safer, less toxic alternative to previous refridgerants.
