APPARATUS AND METHODS FOR MANUFACTURING A GLASS RIBBON

Abstract:

A glass manufacturing apparatus includes a vessel and a filter positioned to receive a beam of light. The filter passes a second wavelength component of the beam of light through the filter while preventing a first wavelength component from the beam of light from passing through the filter. The glass manufacturing apparatus comprises a sensor positioned to receive the second wavelength component that has passed through the filter and that has been reflected within the vessel. Additionally, methods of determining a level of molten material within a glass manufacturing apparatus and methods of manufacturing glass are provided.
