US Patent 11767255 Glass compositions and methods with steam treatment haze resistance

Glass-based articles that include a compressive stress layer extending from a surface of the glass-based article to a depth of compression are formed by exposing glass-based substrates to water vapor containing environments. The glass-based substrates have compositions selected to avoid the formation of haze during the treatment process. The methods of forming the glass-based articles may include elevated pressures and/or multiple exposures to water vapor containing environments selected to avoid the formation of haze during the treatment process.
