METHODS OF ADJUSTING GLASS MELTING AND FORMING TEMPERATURES WITHOUT SUBSTANTIALLY CHANGING BENDING AND ANNEALING TEMPERATURES AND GLASS ARTICLES PRODUCED THEREBY

摘要

A method is provided for adjusting, e.g., lowering, the melting and/or forming temperatures of a glass composition without substantially changing the bending and annealing temperatures of the glass composition. The method includes increasing the amount of CaO and decreasing the amount of MgO in the glass composition by the same or about the same amount.
