ABSTRACT:
Glass frits are disclosed which are essentially free of lead and contain 0.05 to 15 mol-% sulfur and/or sulfides, preferably zinc sulfide. A process is disclosed for producing a glass frit by melting a mixture of oxides and/or non-oxide compounds (fluorides, carbonates) at temperatures of 1,000.degree. to 1,300.degree. C., followed by sudden cooling, characterized in that the glass frit contains between 0.05 and 15 mol-% sulfur, zinc sulfide or other sulfides. The glass frits can be used in enamel barrier layers for stopping the migration of silver.
