Abstract
An apparatus for manufacturing tempered glass. A transportation unit transports a glass substrate that is intended to be tempered. An ionizer ionizes alkali oxides in the glass substrate by radiating energy onto the glass substrate. A dielectric heating unit increases the temperature of the inner portion of the glass substrate in which the alkali oxides are ionized by the ionizer.
