Publication number: 20170210666Abstract: A coated glass article and of a system and method for forming a coated glass article are provided. The process includes applying a first coating precursor material to the first surface of the glass article and supporting the glass article via a gas bearing. The process includes heating the glass article and the coating precursor material to above a glass transition temperature of the glass article while the glass article is supported by the gas bearing such that during heating, a property of the first coating precursor material changes forming a coating layer on the first surface of the glass article from the first precursor material. The high temperature and/or non-contact coating formation may form a coating layer with one or more new physical properties, such as a deep diffusion layer within the glass, and may form highly consistent coatings on multiple sides of the glass.Type: ApplicationFiled: January 19, 2017Publication date: July 27, 2017Inventors: Theresa Chang, Ming-Huang Huang, Linda Gaskill, Peter Joseph Lezzi, Kevin Lee Wasson
