A high silica glass composition comprising about 92 to about 99.9999 wt. % SiO_(2 )and from about 0.0001 to about 8 wt. % of at least one dopant selected from Al_(2)O_(3), CeO_(2), TiO_(2), La_(2)O_(3), Y_(2)O_(3), Nd_(2)O_(3), other rare earth oxides, and mixtures of two or more thereof. The glass composition has a working point temperature ranging from 600 to 2,000 C. These compositions exhibit stability similar to pure fused quartz, but have a moderate working temperature to enable cost effective fabrication of pharmaceutical packages. The glass is particularly useful as a packaging material for pharmaceutical applications, such as, for example pre-filled syringes, ampoules and vials.
