A glass enamel composition that may be fired upon a glass substrate to paint an opaques ceramic color. The glass enamel composition is of special utility in the formation of back windows of automobiles in which an electrically conductive heating grid is also to be formed. The glass enamel composition is comprised of lead or lead-free glass flux material, pigment, a printing vehicle, and a aluminum and/or lithium oxide. The aluminum and/or lithium oxide prevents sliding of the ceramic color to fibrous mold surfaces during hot forming the glass substrate. The aluminum and/or lithium oxide functions a migration preventor to prevent the migration of ions of the electrically conductive material to the glass which would, in the absence of the migration preventor, stain the glass.
