1. A method of processing a viscous ribbon comprising:
supplying a molten material from a supply vessel;
forming the molten material into the viscous ribbon, the viscous ribbon traveling along a travel path;
receiving thermal light energy produced from the viscous ribbon;
generating an image of the viscous ribbon from the thermal light energy; and
detecting a defect of the viscous ribbon from the image, the detecting comprising determining a position of the defect.
