H ow ever, in g en eral, the te r m talc is m o re w idely used than the other types of no m en clatu re. The u ses of talc a re varied. Talc is an ingredient for u se in c o s m e tic s , pain ts, p a p e r, ru b b e r, p la stic s , ceram ics and many insecticide preparations. Talcs a r e used in la rg e volum e for dusting and polishing and there are hundreds of sm all tonnage u sers.

An exam ple is the m anufacture of paint. A distinctive grade of talc (m agnesium silicate) is used for outside house paints, another grade for m etal p rim er coatings, and still other g rades of talc for lacquers and cold-w ater paint e m u ls io n s.

A m ineralogically pure talc is an ex trem e ra rity . The te rm " tru e talc" is a b etter p h ra se to use than the te rm "p u re talc". Actually, only a very unusual m an u f a c tu r e r would be in te re s te d in a talc that w as m i n e r alogically pure. Talcs from North Carolina, Montana, California, Nevada, Italy and India com e close to the classification of true talcs. The talcs from these sources are c h a r a c te r iz e d by being low in foreign m a te r ia ls such as iron oxide, c a lc iu m oxide and a lu m in u m oxide.

There are certain industries that require a talc having an extrem ely soft particle, such as the textile indus try. H ere an abrasive particle would tend to w ear the needles, or equipm ent during the m anufacture of the end product. This sam e p ro b le m applies in c e rta in types of ceram ic m anufacturing w here dies lose their exact size quickly if the talc p a rtic le s a re not of ex t r e m e s o ftn e s s .

A fu rth er c h a ra c te ristic of this type of talc is that it has g re a t re s is ta n c e to heat shock when in c o rp o ra te d in a c e r a m ic prod u ct. T h e se ta lc s, lik e w ise, find read y acceptance in body pow ders and for dusting purposes due to these physical p roperties. F ibrous talc is generally asso ciated with talcs c a r r y ing 4 to 6% c a lc iu m oxide. C u rio u s ly enough, if the calciu m is p re s e n t in the fo rm of calciu m carb o n ate, the p articles tend to becom e cry p to -cry stallin e rath er than fibrous. V ariations of this phenom enon o c cu rs in the ta lc s of D eath V alley, in C alifo rn ia, n o rth e rn N ew York state, and are often classed as trem olite types. T hese talc s a re p a rtic u la rly suited for use in paints and ceram ic whiteware. Talcs from Georgia, Maryland, Verm ont, Virginia and Texas a re ch arac te riz ed by the com paratively high iron content which m akes them som ew hat off-color; but due to their other physical p ro p e rtie s, they a re d e sirab le and w idely u sed in paint, ru b b er, foundry and s im ila r industries.

The c e ra m ic industry u ses talc of th ree distinct types. 1. W a l l t i l e , d i n n e r w a r e a n d a r t p o t t e r y m anufacturers generally select a talc containing c alciu m in quantities up to 6% b e c a u s e of the fire d co lo r. 2. E le c tr o n ic in s u la to r m a n u f a c t u r e r s m ust have as chem ically pure talc as available co m m ercially to obtain good di-electric properties. 3. H e a t i n s u l a t o r a n d s p e c i a l i z e d r e f r a c t o r y m anufacturers utilize the higher alum inum bearing talcs as these give m axim um r e sistance to th erm al shock. T alcs g en erally red u ce the tendency to craze and lower m oisture expansion. In the ru b b e r in d u stry talc is u sed for dusting finished pro d u cts and as a fille r ingredient. The quality of source and grind for this industry vary widely, depend ing upon the actual end product of the compound. Toxics used to com bat insects and other pests a re often m anufactured as pow ders and are generally c a r ried and extended with talc. Talc is an excellent m edium for this purpose, and is utilized by insecticide producers. Foundry p ra c tice re q u ire s talc as "Soapstone" to give sm ooth faces to their cores and m olds.

H ere again the quality is dependent upon the final grade of paper product produced. Talc is re q u ire d by a m ultitude of other in d u stries but since the actual tonnage is relatively sm all, they a re not d e s c rib e d in detail, but a r e lis te d in the "U se E n cyclopedia" .

Odd qualities of block talc have been produced in the United States, but from all presently known sources in the w o rld the supply of high quality block talc is so lim ited that its use is not recom m ended. A frican W onder stone is an available m in eral that can be m a c h in e d or c a rv e d as block talc.

The No. 921 W o n d ersto n e is m in e d in l a r g e b lo ck s often weighing several hundred pounds each. As m ined the W onderstone is d a rk g ray to b lackish in color. It can be m achined with h ig h -sp eed wood w o rk ing tools into any shape d esired . The W onderstone actually m achines easier than wood. When fired at approxim ately 1800F the W onderstone becom es a hard ceram ic. The fired color is a buff col o r in oxidizing a tm o s p h e re s . The ab so rp tio n on the fired W onderstone is low and the o v e r-a ll dim ensions will be slightly la rg e r as it expands during firing.
