Abstract
The present invention provides a holder that prevents a glass substrate from deforming during a chemical reinforcing process. The holder includes supporting members, each of which has a plurality of supporting concave portions. The supporting members are formed from a flat plate having a constant thickness so as not to have a portion having high thermal capacity. When the glass substrate is cooled, a thermal stress is not applied to the glass substrate.

12. A holder for immersing a glass substrate in a chemical reinforcing liquid, the holder comprising:
-
a frame;
a first supporting plate mounted on the frame, the first supporting plate having a first serrate portion that defines a first concave portion for receiving a first portion of the glass substrate;
a second supporting plate mounted on the frame, the second supporting plate having a second serrate portion that defines a second concave portion for receiving a second portion of the glass substrate; and
a third supporting plate mounted on the frame, the third supporting plate having a third serrate portion that defines a third concave portion for receiving a bottom portion of the glass substrate. - View Dependent Claims (13, 14, 15, 16, 17)
