Japanning is an ancient decorative technique used to create a glossy, black finish on metal or wood surfaces. It was first developed in Japan during the Edo period and has since been adopted by European craftsmen. The technique involves coating a surface with multiple layers of varnish or lacquer and then polishing it to create a shiny, glossy finish. Modern uses of japanning include furniture pieces like chairs and tables, as well as hobbyist projects that require an attractive glossy finish while also providing protection against wear-and-tear.
