Etching is a method of making prints from a metal plate, usually copper. The copperplate is first coated with an acid-resistant substance, called the etching ground, through which the design is drawn with a sharp tool. The plate is then exposed to nitric acid or dutch mordant, which eats away those areas of the plate unprotected by the ground, forming a pattern of recessed lines. These lines hold the ink, and, when the plate is applied to moist paper, the design transfers to the paper, making a finished print.

More importantly, it has to har-monize with the aesthetics of the piece.

Urushi lacquer has a unique luster and provides great protection for anything that it is applied up-on, and can be applied upon practically any surface. When the Urushi dries, it provides a hard coating that is waterproof and protects the coated object against mold and weather conditions.
