  • GLASS MATERIAL PRODUCING METHOD AND GLASS MATERIAL
    Publication number: 20240343626
    Abstract: Provided is a method for producing a glass material whereby a glass material less likely to undergo solarization can be obtained. A method for producing a glass material includes the steps of: preparing a glass; and subjecting the glass to heat treatment for six or more hours at a temperature of not lower than (Tg?70°) C and not higher than (Tg+40°) C where a glass transition point of the glass is represented as Tg (° C.).
