    • This invention relates to a method of making soda-lime-silica based glass. In certain example embodiments, boron oxide (e.g., B 2 O 3 ) 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.
    • 本发明涉及一种制造钠钙二氧化硅基玻璃的方法。 在某些示例性实施方案中,在玻璃中使用氧化硼(例如B 2 O 3 O 3)以减少精炼时间(或提高其提炼速度)。 或者以硼酸,四硼酸钠五水合物,四硼酸钠十水合物,五水合钠或任何其它合适形式的形式将硼氧化物引入玻璃批料或熔融。 在某些示例性实施方案中,所得到的钠钙二氧化硅基玻璃最终包括约0.1至3%,更优选约0.1至2.5%,最优选约0.5至2.0%(例如约1%), 氧化硼。 已经发现,使用氧化硼和/或将其引入玻璃中的形式是有利的,因为其允许玻璃的精炼时间显着降低。
