摘要:
The invention relates to temperature stable coloured glass and more particularly to glass for automotive signal lamps. A glass composition is described, which comprises a colloid in a soda lime glass, characterized in that soda lime glass has a specific resistance of 10 8 Ω.cm at a temperature of at least 300°C. The invention also relates to coloured hollow glass articles and in particular red ruby copper glass articles, having a specific tin oxide: copper oxide ratio to prevent copper crystallisation during their production process.
