Abstract: A method of manufacturing a glass ribbon can comprise flowing a glass-forming ribbon along a travel path. The glass-forming ribbon can comprise a first major surface and a second major surface opposite the first major surface. A thickness can be defined between the first major surface and the second major surface. The method can comprise heating the first major surface of the glass-forming ribbon at a target location of the travel path while the glass-forming ribbon is travelling along the travel path. The heating can increase a temperature of the glass-forming ribbon at the target location to a heating depth of about 250 micrometers or less from the first major surface. The method can comprise cooling the glass-forming ribbon into the glass ribbon. Prior to the heating, the glass-forming ribbon at the target location can comprise an average viscosity in a range from about 1,000 Pascal-seconds to about 1011 Pascal-seconds.
