    How is tempered glass made? What is the process by which it is produced for use in wood stoves or fire place doors?


    Tempered glass is glass which has been heated to a certain temperature and then cooled. This changes it's properties.

    Glass used in woodstoves and fireplaces is rarely tempered...most is a ceramic glass which is good to 1000 degrees plus...tempered starts going at about 500 degrees.

    The exception are some fireplace glass doors, which use tempered if they have a lot of cooling air flowing around them.
