The present invention provides a surface-treating agent comprising a fluorine-containing compound having a carbon-carbon unsaturated bond at its molecular terminal as a group of —Y-A wherein Y is a single bond, an oxygen atom or a divalent organic group, and A is —CH═CH.sub.2 or —C≡CH, which is able to form a layer having higher alkaline resistance.

A glass treatment apparatus comprises an upstream applicator comprising a first surface. The first surface is movable between a first upstream position where the first surface is within a travel path of the glass treatment apparatus while extending across a travel direction of the travel path and facing a downstream direction opposite the travel direction, and a second upstream position where the first surface is outside the travel path. Additionally, methods of treating a glass ribbon with the glass treatment apparatus are disclosed.

The present invention relates to a method for manufacturing tempered glass and, more specifically, to a method for manufacturing alkali-free glass which has the thickness of 2.0 mm or less into tempered glass by means of heat treatment and surface treatment using fluosilicic acid. To this end, the present invention provides a method for manufacturing tempered glass, the method comprising: a preparation step for preparing alkali-free glass; a surface treatment step for surface-treating the alkali-free glass by means of a surface treatment solution comprising fluosilicic acid and thereby generating on the surface of the alkali-free glass a porous SiO.sub.2-rich layer of which the coefficient of thermal expansion (CTE) is smaller than the CTE of the inner part of the alkali-free glass; and a heat treatment step for heat-treating the alkali-free glass that has been surface-treated and thereby generating compressive stress on the surface of the alkali-free glass.
