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.
A porous ceramic abrasive body comprising a mildly abrasive particulate, a vitrified glass frit and clay bond and a plurality of interconnecting voids substantially uniform in size and distribution throughout the body, a convex top surface on the body, a concave bottom surface on the body and a circumferential sidewall surface on the body, the surfaces gently blending together to form a generally rounded body, and the surfaces being interrupted by a multiplicity of the interconnecting voids to form a mildly abrasive surface.
The ceramic abrasive body of claim 10 comprising about 65% by weight abrasive particulate of 140/320 mesh spread and about 35% by weight vitrified glass frit and clay, the ceramic abrasive body having a density of approximately 1.98 to 2.12 grams per cubic centimeter and the liquid soap of about 2500 centipoise viscosity.
