摘要: Mineral materials selected from lithium aluminosilicate glasses containing vanadium, precursors of glass-ceramics, and glass-ceramics colored by vanadium contain solid solution(s) β-quartz and/or β-spodumene as main crystalline phase. Also disclosed are articles made said mineral materials, well methods for forming glasses, glass-ceramics. Methods involve optimizing the refining SnO 2 a fining agent in preparing or
