Abstract

A method for annealing a glass disk is disclosed. The glass disk is placed on a base, whereby the bottom surface of the glass disk makes a contact with the base, and the top surface of the glass disk is exposed to air. The glass disk is heated with thermal energy supplied to the glass disk, the thermal energy comprising first thermal energy supplied from the air through the top surface and second thermal energy supplied from the base through the bottom surface.
