TALC

TALC
Talc, when mentioned to most people, at once suggests faces powder, just as graphic suggests pencils. But face powder is an unimportant use of talc from the standpoint of the amount used every year. Ground up talc is used as a filler for paper; in rubber, paint, and in glass making; and to coast the surface of roofing material so that it will not stick together when rolled.

Large slabs of talc are made into laundry tubs, sinks, and the acid proof tops of laboratory work benches. Swetchboard panels and many other things which must be nonconductors of electricity are also made from slabs of talc, because this stone can be easily bored and cut to shape. For these and many other uses, we mine around three million dollars worth of talc every year.
