    摘要: A method of making glass through a glass ribbon forming process in which a glass ribbon is drawn from a root point to an exit point is provided. The method comprises the steps of: (I) cooling the glass ribbon at a first cooling rate from an initial temperature to a process start temperature, the initial temperature corresponding to a temperature at the root point; (II) cooling the glass ribbon at a second cooling rate from the process start temperature to a process end temperature; and (III) cooling the glass ribbon at a third cooling rate from the process end temperature to an exit temperature, the exit temperature corresponding to a temperature at the exit point, wherein an average of the second cooling rate is lower than an average of the first cooling rate and an average of the third cooling rate.

    摘要: Computer-implemented methods and apparatus are provided for predicting/estimating (i) a non-equilibrium viscosity for at least one given time point in a given temperature profile for a given glass composition, (ii) at least one temperature profile that will provide a given non-equilibrium viscosity for a given glass composition, or (iii) at least one glass composition that will provide a given non-equilibrium viscosity for a given time point in a given temperature profile. The methods and apparatus can be used to predict/estimate stress relaxation in a glass article during forming as well as compaction, stress relaxation, and/or thermal sag or thermal creep of a glass article when the article is subjected to one or more post-forming thermal treatments.

    摘要: 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.
