The product to be imaged is coated with a resist (a protective coating that resists the acid). An image is exposed on the resist, usually photographically, leaving bare metal and protected metal. The acid attacks the exposed metal thus leaving the image etched into the surface of the metal. Very fine lines can be reproduced by this process and the only tooling is a piece of film, so specific samples are easily-made.
Chemically or hand-created designs or patterns cut into the surface.
A design that is imparted to a spoon with acid, producing shallow relief. Illustration here.
An artwork imprint method where an image is covered with a protective coating that resists acid. The image is then exposed, leaving bare metal and protected metal. The acid attacks only the exposed metal, leaving the image etched onto the surface.
Imprinting method in which the product to be imaged is coated with a protective coating that resists acid. The image is then exposed, leaving bare metal and protected metal. The acid attacks only the exposed metal, leaving the image etched onto the surface.
Design formed in pottery by removing surface of pottery, sometimes called sgraffito
An etched finish is created on a metal's surface by using harsh chemicals to eat into the surface or by cutting into the surface using a sharp tool.
Very faintly carved decoration scratched onto the surface of a piece.
