Acid etched metal is produced by exposing a film positive, called the "tool" onto a thin metal sheet that has been coated with a photo sensitive polymer. Acid is then used to etch completely or partially through the metal surfaces not protected by the hardened polymer. Depending on the product, after etching, the metal can be plated and formed into highly decorative products, or used for highly technical applications. Different applications will use metals from brass sheet to stainless steel.
Etched metal works well for ornaments—it can be designed to be two-dimensional or even three-dimensional and has various decorating options.
White Metal Casting
Soft metals, usually containing large amounts of tin, are spin cast into special rubber molds. After casting and cleaning, the parts are plated and/or assembled.
White metal castings work well for fashion jewelry, ornaments,
tie-ons and other ornamental uses.
Hard metals are melted and poured into a special ceramic mold. After the metal cools, the ceramic is broken away leaving the metal shapes that are cut from the pouring "tree", cleaned, and polished. This process is more costly than white metal casting and is generally used for higher quality jewelry of Silver or Gold or for other metals that have higher melting temperatures.
