JAPANNING , the See also:

art of coating surfaces of See also:metal, See also:wood, &c., with a variety of varnishes, which are dried and hardened on in stoves or hot See also:chambers. These drying processes constitute the See also:main distinguishing features of the art. The See also:trade owes its name to the fact that it is an See also:imitation of the famous lacquering of See also:Japan (see JAPAN: Art), which, however, is prepared with entirely different materials and processes, and is in all respects much more brilliant, durable and beautiful than any See also:ordinary japan See also:work. Japanning is done in clear transparent varnishes, in See also:black and in See also:body See also:colours; but black japan is the most characteristic and See also:common See also:style of work. The See also:varnish for black japan consists essentially of pure natural asphaltum with a See also:pro-portion of See also:gum See also:anime dissolved in See also:linseed oil and thinned with See also:turpentine. In thin layers such a japan has a See also:rich dark See also:brown See also:colour; it only shows a brilliant black in thicker coatings. For See also:fine work, which has to be smoothed and polished, several coats of black are applied in See also:succession, each being separately dried in the See also:stove at a See also:heat which may rise to about 300° F. Body colours consist of a basis of transparent varnish mixed with the See also:special See also:mineral paints of the desired colours or with See also:bronze powders. The transparent varnish used by japanners is a See also:copal varnish which contains less drying oil and more turpentine than is contained in ordinary painters' oil varnish. Japanning produces a brilliant polished See also:surface which is much more durable and less easily affected by heat, moisture or other influences than any ordinary painted and varnished work. It may be regarded as a See also:process intermediate between ordinary See also:painting and enamelling. It is very extensively applied in the See also:finishing of ordinary ironmongery goods and domestic See also:iron-work, See also:deed boxes, See also:clock dials and See also:papier-mache articles.

The process is also applied to blocks of See also:

slate for making imitation of black and other See also:marbles forchimneypieces, &c., and in a modified See also:form is employed for preparing enamelled, japan or patent See also:leather.
