Beschreibung
Zusammenfassung:	A glazing includes at least one substrate, one portion of which includes an electrically conductive element, the conductive element including a connector made of chromium-containing steel, which connector is soldered with a solder based on tin, silver and copper to an electrically conductive track, wherein the electrically conductive track, which is formed by fritting a silver paste including a mixture of silver powder and glass frit, has a resistivity measured at 25° C. lower than or equal to 3.5 μΩ·cm and a porosity level lower than 20%, the porosity level being measured by scanning electron microscopy from a cross section through the portion of the substrate including the electrically conductive track and having been polished beforehand by ion milling.
