It is used as a poultice, a desiccating insecticide, a decolorizer and filtration aid for purifying oils, fats, and waxes, an inert pigment, a filler in paper, paint, brick, floor tiles, ceramics, linoleum, plastic, soap, and detergent, an insulation for boilers and blast furnaces, as sound insulation, and as a very mild abrasive in metal polishes and toothpaste. It reduces gloss, acts as a suspending agent, increases viscosity, and absorbs dyes well, thus is used as a base for lake colors. ]]></note></mads>
