Abstract

A chemically reinforced glass having a compressive stress layer formed in the surface layer thereof by ion exchange, characterized in that it has two types of compressive stress patterns in the compressive stress layer: an A type pattern present nearer to the surface of the glass, and a B type pattern present in the side of an inner layer of the glass; a first method and a second method for producing the chemically reinforced glass: a fist method wherein, after the immersion treatment for ion exchange, a second immersion treatment is carried out at a temperature higher than that for the previous immersion treatment by 20 to 50 DEG C for 10 to 60 minutes, and a second method wherein, after a first immersion treatment for ion exchange, a second immersion treatment is carried out at a temperature higher than that for the first immersion treatment by 20 to 50 DEG C for 10 to 60 minutes.
