Abstract: An inorganic or organic glass product, or tempered glass product excellent in weatherability, water resistance, moisture resistance and abrasion resistance, which is formed of a) a silicate glass substrate, b) a porous modified layer enriched with silicon oxide through removal of components other than silicon oxide in a surface layer of the silicate glass substrate, and c) a water-repellent layer formed of at least one compound of an organic silicon compound and an organic fluorine compound on a surface of the porous modified layer.

Abstract: Carbon film coated glass is disclosed which includes a glass substrate, an intermediate layer formed on a surface of the glass substrate in a thickness of 50 angstroms or more and including metallic oxide in an amount of 5% or more by mole and balance of carbon at least, and a carbon film formed on a surface of the intermediate layer in a thickness of 10 angstroms or more. The intermediate layer closely binds the glass substrate and the carbon film together, and thereby it inhibits the carbon film from coming off. The carbon film coated glass is thus improved in the durability. Additionally, the carbon film can include fluorine which is combined with its surface at least, and thereby it improves the repellency of the carbon film coated glass as well as the transparency thereof.
