Method of making float glass

摘要

Soda-lime-silica based glass is provided so as to have an improved (i.e., reduced USPX value). In certain example embodiments, the USPX value may be reduced in a desirable manner by reducing alumina and sodium content, while increasing content of material(s) such as MgO and/or CaO. The lower the USPX value, the better the stain resistance of the glass.
