Silver ANTITARNISH 616 is an organic anti-tarnish process based on nano technology. Special nano polymers get absorbed on the silver surface and crosslink to form a protective layer of a few nano-metres thickness. If Makeup Salt PLUS is additionally used and an electrical voltage is applied, the antitarnish can be applied to the surfaces to be protected in an even better and safer way. Mainly in Asia, tons of jewellery are still being treated with antitarnish processes containing highly toxic, ecologically harmful and inexpensive chromium(Vl) compounds (so-called chromate treatments). However, Chromium reatments are known to be carcinogenic. Antitarnish 616 + therefore is safer, non-toxic, longer lasting and eco-friendly.
