Abstract

This invention is related to the production of glasses having compositions within the copper and/or silver-halide-phosphate field, wherein at least one halide is present selected from the group of fluoride, chloride, bromide, and iodide, such glasses exhibiting softening points below about 400.degree. C., coefficients of thermal expansion (25.degree.-300.degree. C.) in excess of about 180.times.10.sup.-7 /.degree.C., high electrical conductivity, and electrochromic behavior. The copper-containing glasses may also demonstrate thermochromic properties.
