A vitreous enamel resistor material comprising a mixture of a vitreous glass frit and fine particles of tantalum. The vitreous enamel resistor material may also include fine particles selected from titanium, boron, tantalum oxide (Ta2O5), titanium oxide (TiO), barium oxide (BaO2), zirconium dioxide (ZrO2), tungsten trioxide (WO3), tantalum nitride (Ta2N), titanium nitride (TiN), molybdenum disilicide (MoSi2), and magnesium silicate MgSiO3). An electrical resistor is made from the resistor material by applying the material to a substrate and firing the coated substrate to a temperature at which the glass melts. Upon cooling, the substrate has on a surface thereof a film of glass having the tantalum particles and particles of the additive material, if used, embedded therein and dispersed therethroughout.
