Anodized refers to a process that increases the thickness of the natural oxide layer on the surface of metal parts, enhancing their durability, appearance, and resistance to corrosion. In the context of jewellery, anodizing is often used to create vibrant, colourful finishes on metals, especially titanium and aluminium.
Process
Anodizing involves immersing the metal in an electrolytic solution and applying an electric current. This process causes the surface of the metal to oxidize, forming a protective and decorative oxide layer. The thickness and properties of this layer can be controlled by adjusting the electrical voltage and the composition of the electrolytic solution.
Colour Variation
By altering the voltage during the anodizing process, a wide range of colours can be achieved on metals like titanium. This is because the oxide layer changes the way light refracts off the surface, producing different colours without the need for dyes or pigments.
Durability
Anodized jewellery is highly resistant to scratching, wear, and corrosion. The oxide layer created during anodizing is harder than the base metal, providing added protection and longevity.
Maintenance
Anodized jewellery is relatively low maintenance. The anodized surface is easy to clean with mild soap and water, and it retains its colour and finish well over time.
Applications in Jewellery
Anodizing is popular for creating colourful and unique pieces of jewellery, such as rings, bracelets, and earrings. The ability to produce a variety of colours and finishes makes anodized jewellery highly customizable and appealing for those seeking distinctive and vibrant designs.
Anodizing enhances the beauty and durability of metal jewellery, making it a favoured technique for creating unique and long-lasting pieces.
