PURPOSE: A manufacturing method of artificial mineral stone containing minerals such as yellow earth and quartz porphyry is provided. Therefore, the resultant mineral stone emits anions and far infrared rays for our health improvement. CONSTITUTION: The artificial mineral stone is manufactured by mixing 30-35wt.% of yellow earth, 10-15wt,.% of quartz porphyry, 10wt.% of magnetite/iron, 5wt,% of salt, 25wt.% of soil/sand and 15wt.% of water, followed by sintering over 1400deg.C for 10-15hrs. The manufactured mineral stone is processed to various shapes such as tile, block, sphere, natural stone, etc.
