<p>A glass article covered with a colored film, comprising a glass substrate having a surface covered with a colored film, the colored film being composed mainly of, on the weight basis, more than 50 to 95 % of silicon oxide, 0 to 30 % of at least one member selected among zirconium oxide, tantalum oxide and titanium oxide, 0 to 25 % of cerium oxide, and 5 to 20 % of gold in the form of fine coloring particles, the thickness of the colored film being at most 180 nm, the glass substrate having a visible light reflectance of 10.0 % or below on the side not covered with the film. This article is characterized by a low visible light reflectance attained by taking advantage of a surface plasmon absorption of the fine particles of gold.</p> |
