>Japanning is a term used to describe a black finish that was originally accomplished using lacquers (Rhus vernicifera) and became a term for that type of finish.
The traditional japan formula is made with asphaltum and a varnish and can be baked but it is not necessary, just makes it dry faster. It is a brown black and it can not be achieved by modern finishes. It is used on tools, tin ware and woodwork e.g. Hitchcock chairs. and other objects including leather, the finish remains slightly flexible.
