ABSTRACT:
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.
