Zusammenfassung:	Apparatuses and methods are described for preventing and/or controlling an accumulation of devitrified glass during glass production, particularly on a glass forming apparatus for producing a glass ribbon and/or on an edge director of the glass forming apparatus. The apparatuses and methods employ a laser beam to heat a particular portion of the glass forming apparatus, the edge director, molten glass, and/or the devitrified glass.
