Method of refining a lithium aluminosilicate glass and glass-ceramic obtained |
摘要 |
The present invention relates to a method of refining lithium aluminosilicate glass capable of being controllably ceramized and free of arsenic oxide, antimony oxide and tin oxide, in which at least 0.05% by weight of at least one sulfide is added to the glass batch materials and said materials are melted at a temperature below 1750° C. The invention also relates to the glass-ceramics obtained from said colored glass, especially glass colored by vanadium oxide, and cooktops and cooking utensils including such glass-ceramics. |
