LEAD- AND ARSENIC-FREE BOROSILICATE GLASS HAVING IMPROVED MELTING CHARACTERISTIC |
摘要 |
A lead- and arsenic-free borosilicate glass having an improved melting characteristic is described. The melting rate of the glass was improved dramatically by making the composition substantially free of MgO and CaO and adding 1.0 to 4.0 weight percent BaO. The improved melting characteristic yielded up to a ninety-nine percent reduction in the number of unmelted batch stones.
