  • Patent number: 5595579
    Abstract: A liquid soap absorbent, liquid soap dispensing synthetic ceramic stone of specified porosity with interconnecting voids throughout the body of the stone. The surface of the stone is mildly abrasive in a soap and water milieu. The interconnecting voids are substantially uniform enabling a liquid soap to thoroughly penetrate the stone by capillary action. In use, the liquid soap is continuously dispensed by dissolution in water and the aspirating action caused by a concave bottom surface of the stone and the seal provided by soap, water and skin at the point of use. As the liquid soap is drawn from the stone the interconnecting voids are cleared of the soap. With the depletion of the liquid soap from the stone a fresh charge of liquid soap is accomplished by merely placing the depleted stone in a shallow receptacle filled with liquid soap.

  • Patent number: 4736548
    Abstract: A process for artificially producing a relatively high density, tinted novaculite Washita stone of relatively homogenous characteristics, and the artificial stone product thereby produced. Tinted and untinted layers of abrasive mix are combined in a lateral pressing step to provide a composite colored stone suitable for subsequent vitrification. The untinted mixture preferably is preferably made from 100 mesh novaculite powder, but alternatively a blend of approximately 100 mesh and 200 mesh novaculite powder is employed. The is mixed with a wetting agent and water, a temporary binder, a flux, and a high refractory frit, yielding the following approximate constituency by weight: approximately 64% of said 100 and 200 mesh novaculite; 5-6% of a temporary binder, approximately 3% of the wetting agent, approximately 2% flux, and approximately 23-25% frit. After screening, the first mixture is completed by blending with ball clay.
