SOLUTION: The surface for the outside of a wated glass article 10 particularly having an inside flank and the surface for the outside which periodically comes into contact with water has the outer coating 20 for putting the water into a sheet form. This coating is made of a carbon layer formed by direct sputtering on the surface for the outside at a thickness of 15 to 100Å.
