Abstract: This invention relates to a method of making soda-lime-silica based glass. In certain example embodiments, boron oxide (e.g., B2O3) is used in the glass for reducing the refining time (or increasing the refining rate) thereof. The boron oxide may be introduced into the glass batch or melt in the form of boric acid, sodium tetraborate pentahydrate, sodium tetraborate decahydrate, sodium pentahydrate, or in any other suitable form. In certain example embodiments, the resulting soda-lime-silica based glass ends up including from about 0.1 to 3%, more preferably from about 0.1 to 2.5%, and most preferably from about 0.5 to 2.0% (e.g., about 1%), boron oxide. It has been found that the use of boron oxide, and/or the form in which the same is introduced into the glass, is advantageous in that it permits the refining time of the glass to be substantially reduced.
