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 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.

Une méthode est donnée pour ajuster, par exemple, abaissement, les températures de fonte et/ou de formation de composition de verre sans changer sensiblement les températures de recourbement et de recuit de composition de verre. La méthode inclut augmenter la quantité de cao et diminuer la quantité de MgO dans la composition de verre par la même chose ou la quantité à peu près identique.
