Nowadays, most people would rather die than go anywhere near anything containing asbestos, but there was once a time when people literally sprinkled themselves with fake snow containing the proven carcinogenic.
Up to the late 1920s, cotton was the main ingredient used for fake snow on Hollywood film sets and in people’s households, but in 1928 a firefighter raised questions about the safety of cotton fake snow, noting that it was a fire hazard, and proposing the used of asbestos as a safer alternative. Obviously, this was long before we realized that asbestos was a known risk factor for an aggressive form of cancer known as mesothelioma, but still, the fact that people used asbestos-containing holiday decorations for decades is shocking.
