Oxidation

Oxidation refers to a chemical reaction where a material, especially a metal, combines with oxygen, leading to a change in appearance.

Part of speech: noun
Definition: In jewelry making, oxidation is a deliberate process used to enhance the aesthetic appearance and detail of metal pieces, particularly silver and copper. When these metals undergo oxidation, they develop a patina, a layer that may exhibit various colors or a darkened hue, adding depth and contrast to the design. This characteristic is especially valued in antique and vintage-style jewelry, where the appearance of age and distinction is desirable. The process can be controlled and reversed through polishing, allowing jewelers to achieve a balance between the original shine of the metal and the character introduced by oxidation.
