A low dielectric, low temperature fired glass ceramic produced by firing at about 800.degree.-900.degree. C. a mixture comprising at least one glass consisting of, by weight percent, 0 to 50% B.sub.2 O.sub.3, 35 to 65% CaO, and 10 to 65% SiO.sub.2, and selected from the glasses of CaO-B.sub.2 O.sub.3 -SiO.sub.2 glass system. The glass ceramic is light weight, exhibits a dielectric constant of less than about 7.9, has adequate mechanical strength and thermal conductivity, and is compatible with precious metal conductors. The glass ceramic is useful in the manufacture of integrated circuits and any other electronic or mechanical components where a glass ceramic exhibiting this particular combination of characteristics is suitable.
