Abstract
Disclosed is a technique for melting X-ray absorbing glass compositions by a process wherein molten glass is floated or supported on a bath of molten tin. The X-ray absorbing glass compositions are free of the oxides of lead, arsenic, antimony, bismuth, cadmium, and other readily reducible oxides to prevent discoloration of the glass upon contact with molten metal.
