1. A process for the production of a detergent composition, comprising:

  • adding effective detergent amounts of sodium oxide and potassium oxide to a ceramic material formed primarily of silicon oxide and aluminum oxide, whereby a dry ceramic powder is obtained;

    adding water to the dry ceramic powder;

    kneading and forming the resulting mixture into a predetermined shape, whereby a green body is obtained;

    drying the green body;

    firing the thus-dried green body at 500°

    C. to 700°

    C.;

    impregnating the resulting fired body with an effective detergent amount of an aqueous solution of sodium metaphosphate; and

    firing the thus-impregnated body again at a temperature in a range of from 200°

    C. to 400°
