Abstract
PURPOSE: To easily remove or reduce Griffith flaws, etc. by a method wherein latent flaw section of glass is treated with etching, is heated, and undergoes vacuum treatment before or after contacting inert gas.
CONSTITUTION: Minute flaws such as Griffith flaws on glass surface are treated by etching. Then, the glass is heated, and/or after cooling, is vacuum treated either before or after contacting inert gas. This vacuum treatment removes OH group chemically bonded to the glass being treated and prevents latent flaws from growing. This simple method removes or reduces surface latent flaws, thereby preventing product breakage or mechanical damage.
