Applications on Silver Jewelry

Without protection, silver jewelry can turn yellow or black with time due to chemical reactions. To slow or stop these reactions the surface of silver jewelry is often covered with a temporary (wax-based) or permanent protective coat (varnish-based). Tarnishing on the surface of the metal often results in a decline in the surface tension to under the recommended 38 mN/m.

Temporary protection against tarnishing:Permanent protection against tarnishing:
  • Wax-based
  • Varnish-based
  • Low surface tension
  • Surface tension depends on varnish
Recommendation: Protect the rest of the piece after gluing Recommendation: Use a tarnishing protection system with sufficient surface tension
