Abstract
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.
