Oxidation is a chemical process in which metals like silver, sterling silver etc. are exposed to oxygen or sulphur under controlled conditions for an extended period of time to obtain a blackened appearance. When such metals are treated with sulphur, the compound silver sulfide formed on its outer layer provides a dark black finish, resulting in a tarnished antique look. Oxidation of metals also creates a shadow effect and a fresh appearance. Such metals can be used to make ornaments such as necklaces, chains, bangles, earrings, anklets etc.
Coloured beads and gemstones can be combined with oxidized bangles to obtain a traditional finish.
Oxidized bangles are available in various attractive designs, styles and shapes. Tarnished sterling silver bracelets with specific gemstones and gold plated oxidized bangle bracelets are major novelties in this category. Other elegant designs are oxidized stone studded bangles, oxidized beaded pair bangles, apsara silver bracelets and antique silver kadas.
Here are a few benefits of using oxidized bangles.
Do not have to be polished and cleaned periodically. Tarnishing reduces the efforts of cleaning.
Can be left in any environment.
Provide a vintage look.
Rate of corrosion is controlled.
Cost-effective when compared to other precious metals like gold, silver, platinum etc.
The silver sulfide formed on the outer layer can be easily removed, giving the metal back its shine.
It is better to store these ornaments in a cool place away from sunlight. Light sources may turn the colour of oxidized jewellery over time. The colour can also fade when they are exposed to atmospheric gases for a long time.
If you prefer to remove the oxidized layer, it can be done using tarnish remover products. In the case of the oxidized bangles made up of sterling silver, you can remove the silver sulphide build-up and restore its lustre through careful polishing techniques. Cotton swabs and polished clothes can be used for this purpose.
