Book excerpt: Excerpt from Pyrophyllite Deposits in North Carolina Emmons (1856) described a material which was locally known as soapstone at Hancock's Mill, (now Glendon) Moore County and near Troy, Montgomery as follows: A rock, which occurs in extensive beds, and known in the localities where it is found as a soapstone, can by no means be placed properly with the magnesium minerals. It is white, Slaty, or compact translucent, and has the common soapy feel of soapstone, and resem bles it SO closely to the eye and feel that it would pass in any market for this rock. It has, how ever, a finer texture, and is somewhat harder; but it may be Scratched by the nail, so that it ranks with softest of minerals: it scratches. Talc, and is not itself scratched by it; it is infusible before the blowpipe, and with nitrate of cobalt gives an intensely blue color, proving thereby the presence of alumina in place of magnesia. He classed the mineral as agalmatolite, the figure stone Of the Chinese, and described the methods used in quarrying it at Hancock's Mill. Brush (1862) analyzed some of the material from Hancock's Mill, Moore County and Showed it to be pyrophyllite.
