Abstract
A lead and arsenic free borosilicate glass is provided which is suitable for use in electric arc discharge lamps. The glass is tungsten-sealing and provides desirable protection from ultraviolet radiation. In addition, the glass is resistant to surface scum formation during melting and reduces the amount of batched iron which must be added for UVB protection.
