Publication number: 20130047671Abstract: Disclosed is a method of reducing the compaction of glass formed by a down draw process. The glass may be a glass sheet or a glass ribbon. Once the glass is formed, it is thermally treated on a molten metal bath for a time and at a temperature effective to reduce the fictive temperature of the glass below a predetermined level. In one embodiment, a glass ribbon is formed in a fusion process and the glass ribbon redirected onto a molten metal bath where the ribbon is thermally treated.Type: ApplicationFiled: August 29, 2011Publication date: February 28, 2013Inventor: Jeffrey T. Kohli
