Talc Talc Talc or talcum is a clay mineral composed of hydrated magnesium silicate with the chemical formula HMg(SiO) or MgSiO(OH). In loose form, it is (in ratio with or without corn starch) one of the most widely used substances known as baby powder. It occurs as foliated to fibrous masses, and in an exceptionally rare crystal form. It has a perfect basal cleavage, and the folia are not elastic, although slightly flexible. The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 1 as the hardness of talc. Talc can easily be scratched by a fingernail. Talc
Mohs (automobile) SafariKar was introduced in 1972, and was no less exotic than the Ostentatienne. SafariKars were aluminum bodied automobiles, the exterior of which were upholstered in Naugahyde (vinyl) stretched over foam padding. Doors for the vehicle opened outward from the body on linear rods, again for side impact protection. The vehicle had a retractable hard top system. Options for the SafariKar included a television, four-wheel drive, two-way radio and "butane furnace." Only three were produced, probably all in 1972 since an early Mohs publicity photograph shows all three in various stages of assembly. "Production" of the Safari Kar was listed in
