Document Type and Number:
Japanese Patent JP5757246
Kind Code:
B2
Abstract:
To provide a colored glass plate, which uses sodium sulfate (Na 2 SO 3 ) as a refining agent and which is capable of stably maintaining the mass percentage of divalent iron calculated as Fe 2 O 3 in the total iron calculated as Fe 2 O 3 at a high level, while suppressing development of an amber color that is derived from sodium sulfate. A colored glass plate made of alkali-containing silica glass containing elements of iron, tin and sulfur, wherein the percentage of the total sulfur calculated as SO 3 is at least 0.025% as represented by mass percentage based on oxides, the percentage of divalent iron calculated as Fe 2 O 3 in the total iron calculated as Fe 2 O 3 is from 60 to 80% as represented by mass percentage, and the percentage of divalent tin calculated as SnO 2 in the total tin calculated as SnO 2 is at least 0.1 % as represented by mol percentage.
