Reticulation is one of the most interesting ways to create textures in silver. To begin, the silver must be depletion gilded to bring a layer of fine silver to the surface of the metal.
What is depletion gilding? Depletion gilding is the process of creating a layer of fine silver at the surface of a silver alloy. First, the silver is heated sufficiently to cause oxidation of the copper in the surface layer, then the oxidized copper is removed by soaking the silver in a mild acid (pickle) solution (the "depletion"). The heating and pickle process is repeated until a sufficient layer of fine silver has been brought to the surface. This process leaves a thin layer of fine silver on the surface of the metal (the "gilding").
Specially formulated reticulation silver alloy contains a lower percentage of silver and a higher percentage of copper (80/20), making it ideal for reticulation. Done effectively, reticulation presents a beautifully patterned surface finish, which lends itself well to a wide variety of jewelry designs.
Eager to experiment with reticulation? In the following video Mark Nelson demonstrates the technique and shows you how to achieve unexpected, wonderful texture.
