See also:AQUATINT (See also:Lat. aqua, See also:water, and tincta, dyed) , a See also:kind of See also:etching (q.v.) which imitates washes with a See also:brush . There are many ways of preparing a See also:plate for See also:aquatint, the following being recommended by P . G . See also:Hamerton . Have three different solutions of See also:rosin in rectified See also:alcohol, making them of various degrees of strength, but always thin enough to be quite fluid, the weakest See also:solution being almost colourless . First pour the strongest solution on the plate . When it dries it will produce a granulation; and you may now bite as in See also:ordinary etching for your darker tones, stopping out what the See also:acid is not to operate upon, or you may use a brush charged with acid, perchloride of See also:iron being a very See also:good See also:mordant for the purpose . After cleaning the plate, you proceed with the weaker solutions in the same way, the weakest giving the finest granulation for skies, distances, &c . The See also:process requires a good See also:deal of stopping-out, and some burnishing, scraping, &c., at last . Aquatint may be effectively used in See also:combination with See also:line etching, and still more harmoniously with soft ground etching in which the line imitates that of the See also:lead See also:pencil . |
