Abstract:
It is an object of the present invention to provide a method and apparatus for efficiently remove bubbles present on a surface of molten glass, which can solve a problem that bubbles remaining on a surface of molten glass are get inside at a time of forming the glass to cause inside bubbles, to thereby provide a glass substrate of good quality, and which can improve productivity of glass substrates; and to provide a process for producing glass employing the above method for removing bubbles. The present invention provides a method for removing bubbles from molten glass, which is a method for removing floating bubbles on a surface of molten glass, wherein a floating bubble on the surface of molten glass is irradiated with at least one laser beam.
