    • A glass article including at least about 40 mol % SiO2 and, optionally, a colorant imparting a preselected color is disclosed. In general, the glass includes, in mol %, from about 40-70 SiO2, 0-25 Al2O3, 0-10 B2O3; 5-35 Na2O, 0-2.5 K2O, 0-8.5 MgO, 0-2 ZnO, 0-10% P2O5 and 0-1.5 CaO. As a result of ion exchange, the glass includes a compressive stress (σs) at at least one surface and, optionally, a color. In one method, communicating a colored glass with an ion exchange bath imparts σs while in another; communicating imparts σs and a preselected color. In the former, a colorant is part of the glass batch while in the latter; it is part of the bath. In each, the colorant includes one or more metal containing dopants formulated to impart to a preselected color. Examples of one or more metal containing dopants include one or more transition and/or rare earth metals.
    • 公开了包含至少约40mol%SiO 2和任选的赋予预选颜色的着色剂的玻璃制品。 通常,玻璃以摩尔%计含有约40-70SiO 2,0-25 Al 2 O 3,0-10 B 2 O 3, 5-35 Na2O,0-2.5K2O,0-8.5MgO,0-2 ZnO,0-10%P2O5和0-1.5 CaO。 作为离子交换的结果,玻璃在至少一个表面和任选的颜色上包括压缩应力(sigmas)。 在一种方法中,将有色玻璃与离子交换浴通信,在另一种方法中赋予圣诞节; 沟通赋予圣诞节和预选颜色。 在前者中,着色剂是玻璃批料的一部分,而在后者中; 它是浴缸的一部分。 在每个中,着色剂包括配制成赋予预选颜色的一种或多种含金属的掺杂剂。 一种或多种含金属的掺杂剂的实例包括一种或多种转变和/或稀土金属。
