    Abstract: A glass for tungsten halogen lamp glass envelopes, glass filter lenses, and glass filters consisting essentially in terms of weight percent on the oxide basis, of 50-62% SiO 2 , 10-17% Al 2 O 3 , 0-6% B 2 O 3 , 3.6-10% CaO, 0-7.5% MgO, 0.1-0.3% SrO, 2.4-18% BaO, 0-1% ZnO, 1-8% Nd 2 O 3 . The glass exhibits the following physical properties: strain point between about 665°C to about 750°C, coefficient of thermal expansion to the set point of between about 49-59x10 -7 /°C, liquidus temperature below 1320°C, viscosity at liquidus temperature greater than 2,000 poises, and transmission at 585 nm of between 5-60 % for a 1.2 mm thickness. The lamp color temperature for a tungsten halogen lamp containing a glass envelope, a glass filter lens, or a glass filter prepared from the glass composition is increased from about 3 to 7% above a similar glass with no Nd 2 O 3 , and the total visible lumen loss is limited to less than about 10%.
