The present invention is devised to solve the problems of the above-described conventional technologies. The purpose of the present invention is to provide a tempered glass cutting method and cutting apparatus which can prevent the defects of the tempered glass breaking when same is cut and improve the reliability of the product. To this end, provided is a tempered glass cutting method which comprises: a tempering step of generating compressive stress on a glass sheet to temper the glass sheet; a compressive stress relaxation step of applying heat to the cut portion of the tempered glass sheet to relax the compressive stress; and a cutting step of cutting the cut portion.

The present invention relates to an inorganic adhesive composition and to a hermetic sealing method, and more specifically relates to an inorganic adhesive composition with which an organic solvent is not used and to a hermetic sealing method using same. To this end, the present invention provides an inorganic adhesive composition comprising: between 20 and 80 parts by weight of a water glass diluted solution containing between 60 and 90 parts by weight of water glass (Na2SiO2); between 20 and 80 parts by weight of a refractory inorganic filler; and a black pigment.

A method of cutting chemically toughened glass which is chemically toughened in a chemical toughening process of creating compressive stress in the surface of glass by exchanging first alkali ions in the glass with second alkali ions. The method includes the steps of applying a paste on a portion of the chemically toughened glass that is to be cut, heating the paste, and cutting the chemically toughened glass along the portion on which the paste is applied. The paste contains alkali ions. The ion radius of the alkali ions in the paste is smaller than an ion radius of the second alkali ions which substitute the first ions in the chemical toughening process.
