Silver Oxidation
This process chemically creates a layer of silver sulfide on the surface that gives the jewelry a darker, matte finish and antique character. Oxidation also protects items from corrosion. The service requires a minimum of 50 grams per model.
Antitarnish Coating
We provide antitarnish coating, a transparent polymer that protects jewelry from external conditions and discoloration. It can be applied to any of our coatings as well as pure silver. The coating is certified for food contact, so it is also suitable for items such as cutlery.
