A glass object is heated by application of infrared energy and radio-wave energy. A coating is applied to the glass object and the glass object is subject to additional heating with radio-wave energy. The temperature and duration of the additional heating may be sufficient for a pyrolytic reaction to occur between the coating and the glass object. The coated glass object may be cooled either rapidly to temper the glass or cooled gently to anneal the glass.
