Abstract
Mineral materials selected from lithium aluminosilicate glasses containing vanadium, precursors of glass-ceramics, and glass-ceramics colored by vanadium contain solid solution(s) of β-quartz and/or β-spodumene as main crystalline phase. Also disclosed are articles made from said mineral materials, as well as methods for forming said glasses, glass-ceramics and articles of said glasses and glass-ceramics. Methods involve optimizing the refining of lithium aluminosilicate glasses containing SnOas a fining agent in preparing glasses or glass-ceramics.
