Thereafter, in one embodiment of the process, the batch may be heated to between 750 and 850.degree.C to form a liquid melt and then the liquid melt is further heated until the temperature is 1100? 20.degree.C. The temperature of the melt is heldbetween the aforementioned limits for a period of at least 3 hours and no longer than 3 1/2 hours, and thereafter the temperature of the melt is lowered to effectively inhibit bubbling of the liquid melt, and then the melt is removed for further processing.</p> |
