A multi-functional glass product having functions of the negative ions and far-infrared radiation is produced by the mixture of the conventional soda-calcium basis glass composite with one of the natural components Elvan stone, Magnetite (Fe3O4), or Ilmenite (FeTiO3) and a rare earth element of Monazite. Accordingly, the present glass composition comprises a well known soda-calcium basis glass composite containing at least one of SiO2, Al2O3, R2O (wherein, R2O is selectively contained by at least one component of Na2O or K2O) and RO (wherein, RO is selectively contained by at least one component of CaO or MgO), and a glass composite having the function of the far-infrared radiation such as Elvan stone, Magnetite (Fe3O4) or Ilmenite (FeTiO3) and a powdered Monazite. Further, it is possible to compose the glass composition having the function of only negative ions from the mixture of the soda-calcium basis glass compound with the powdered Monazite. Such a glass product of the present invention is also capable to be manufactured as colorless transparent glass products.
