Independent studies have shown that a new raw material for glassmaking can accelerate the melting and refining process.
Raw materials for glassmaking have changed little over the past 2000 years. However, a large-scale initiative under way to commercialize synthetic diopside (CaMg[Si.sub.2][O.sub.6]) [*] for the glass industry as a raw material could have a significant impact on glass production.
While long known as excellent glass formers, natural sources of alkaline earth silicates such as wollastonite (CaSi[O.sub.3]) and diopside tend to be contaminated with both heavy metal and refractory minerals that have precluded their widespread use in ...
