Japan black
Japan black (also called simply japan) is a lacquer or varnish suitable for many substrates but known especially for its use on iron and steel. It is so named due to the history of black lacquer being associated in the West with products from Japan.〔Niimura, Noriyasu; Miyakoshi, Tetsuo (2003) Characterization of Natural Resin Films and Identification of Ancient Coating . ''J. Mass Spectrom. Soc. Jpn''. 51, 440. (JOI:JST.JSTAGE/massspec/51.439 )〕 Its high bitumen content provides a protective finish that is durable and dries quickly. This allowed japan black to be used extensively in the production of automobiles in the early 20th century in the United States. It can also be called japan lacquer and Brunswick black. Used as a verb, ''japan'' means "to finish in japan black." Thus japanning and ''japanned'' are terms describing the process and its products. ==Ingredients== Japan black consists mostly of an asphaltic base dissolved in naphtha or turpentine, sometimes with other varnish ingredients, such as linseed oil. It is applied directly to metal parts, and then baked at about 200°C (400°F) for up to an hour.
