Plaster can also be manufactured in dry form and sold in bags. Whiting is a pure white grade of chalk that has been ground and washed for use in paints, ink, and as an extender in pigments, putty or whitewash. Talc is a fine-grained white, greenish, or gray mineral with a soft soapy texture, which is used in the manufacture of talcum and face powder, as a paper coating, and as a filler for paint and plastics. Emery is a fine-grained mineral used for grinding and polishing. This classification is for the production of the powders only. Machinery includes, but is not limited to:
Conveyors;
Forklifts;
Machinery for crushing, mixing, grinding, milling, washing, or cooking.
This classification excludes:

Asbestos is a fibrous mineral form combined with impure magnesium silicate. Flake asbestos can be mixed, spun and woven into cloth, or the flakes can be used as an ingredient in the processing or treatment of paper. To make molded asbestos products, asbestos is mixed with other ingredients, molded, baked, cut to size, and ground. Mica is also a mineral form; it is split to desired thickness using hand knives or knives mounted on tables. The split mica is sent to punch presses which stamp out the various products usually used by the electrical trades. Mica that is too small to be processed on punch presses may be placed in burling machines, mixed with liquids, and then pressed into sheets. Removal of imperfections is usually done by hand; the sheets are dried, baked in ovens and run through sanders prior to crating and shipping.
This classification excludes:
Establishments engaged in the manufacture of plasterboard or plaster block which are to be reported separately in classification 3104-55;
Contractors engaged in the installation or removal of asbestos or mica products at the customer's site who are to be reported separately in the classification applicable to the phase of construction being performed; and
