Abstract:
A novel multipurpose mineral composition capable of emitting a large quantity of far infrared rays, negative ions and oxygen heat is manufactured by setting up an iron railing, an iron rod and an iron plate on a brazier, placing a tinfoil on the iron plate, and layering yellow soil, kaolin, sericite, and biomineral in sequence on the tinfoil, while inserting the tinfoil between the layers, loading a pulverized elvan in the furnace, pulverizing a mixed stone including 40 wt % of germanium, 15 wt % of true marine, 30 wt % of zeolite, and 15 wt % of franklin, to the particle size under about 44 nullm, and loading the pulverized mixed stone in an internal furnace which is made by winding a copper plate with a tinfoil and placed on the plurality of layers of the furnace, heating the pulverized mixed stone at about 1,000null C. for about seven days into a lump, and repulverizing the lump.
