ABSTRACT OF THE DISCLOSURE A metallization for printing conductor patterns upon a ceramic substrate is disclosed. The metallization is comprised of an admixture of finely divided particles of (1) 60 to 98.5% wt. conductive metal, (2) 20 to 1% wt. inorganic binder, and (3) 20 to 0.5% wt. of a colorant which is a mixture of 5 to 60% wt. of an oxide or oxide precursor of copper, silver or mixtures thereof and 95 to 40% wt. of B2O3 or precursor thereof. The colorant is comprised of no more than 40% wt. of the oxide of silver or 60% wt. of the oxide of copper. The metallization is useful, for example, for making automobile window defoggers.
