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.

Methods of adjusting glass melting and forming temperatures without substantially changing bending and annealing temperatures and glass articles produced thereby

A method is provided for adjusting, e.g., lowering, the melting and/or forming and/or liquidus temperatures of a glass composition which can be accomplished without substantially changing the bending and annealing temperatures of the glass composition. The method includes decreasing the amount of MgO in the glass composition and increasing the amount of two or more or all of CaO, R O (Na O and K O), Al O and SiO by the same or about the same amount.
