Beschreibung
Zusammenfassung:	A method of making a glass includes batching constituents, including silica, alumina, boria, magnesia, quicklime, and strontia, where one or more of the constituents is from "dirty" raw material that includes a relatively large amount of sulfur. The method further includes melting and mixing the batch to make glass having sulfur content but free of blisters, suitable for high performance displays. Un procédé de fabrication d'un verre comprend la mise en lots de constituants, comprenant de la silice, de l'alumine, du bore, de la magnésie, de la chaux vive et du strontium, un ou plusieurs des constituants étant formés à partir d'une matière première "sale" qui comprend une quantité relativement grande de soufre. Le procédé comprend en outre la fusion et le mélange du lot pour fabriquer du verre ayant une teneur en soufre mais exempt de cloques, approprié pour des affichages à haute performance.
