PURPOSE: Provided is a method for manufacturing glass excellent in far infrared emission and sterilization by using natural minerals. The resultant glass is widely used for bioglass, heat resistant vessel, kitchen ware, etc. CONSTITUTION: The far infrared emitting glass is manufactured by mixing 88-96wt.% of sericite, and 1-3wt.% of slaked lime(Ca(OH)2), NaOH, borax and photocatalyst(TiO2), heating a mixture over 1300deg.C for 24hrs or more for melting, and then forming. The size of sericite, slaked lime and borax is less than 30mm, the size of NaOH is less than 43micrometer and the size of photocatalyst is less than 0.5micrometer. The resultant glass has more than 91% of emissivity at 40deg.C and more than 98% of sterilization.
