Production of a conducting coating, especially conducting pathways, on a substrate made of glass and enameled steel comprises applying a layer made of a screen printable paste and calcining the coating at 500-750 degrees C. The paste contains 40-80 wt.% aluminum powder having a d50 value in the region of 1-10 mu m; 5-40 wt.% of one or more glass frits which soften in the region of 400-700 degrees C and having a d50 value in the region of 1-10 mu m; 10-35 wt.% of a liquid or thermoplastic medium made of one or more polymers and/or solvents; 0-10 wt.% of a sintering aid in powder form; and 0-40 wt.% silver powder. Preferred Features: The paste contains 50-75 wt.% aluminum powder having a d50 value in the region of 1-8 mu m; 5-30 wt.% of one or more glass frits having a d50 value in the region of 0.5-5 mu m; 15-25 wt.% organic medium and 0-6 wt.% of one or more powdered sintering aids selected from zinc, magnesium, boron, manganese and carbon.
