ABSTRACT:
An improvement is provided in forming a B.sub.2 O.sub.3 containing glass from heated glass batch agglomerates by using an uncalcined, mineral sodium calcium borate which contains chemically bound water to form the agglomerates. These agglomerates can be heated, prior to melting, to a temperature in excess of that needed to substantially remove all of said chemically bound water without the water release causing the agglomerates to disintegrate.
