CHASING, or ENCHASING , the See also:art of producing figures and ornamental _patterns, either raised or indented, on metallic surfaces by means of See also:steel tools or punches. It is practised extensively for the ornamentation of See also:goldsmith and silversmith See also:work, electro-See also:plate and similar See also:objects, being employed to produce bold flutings and bosses, and in another manner utilized for imitating engraved surfaces. See also:Minute work can be produced by this method, perfect examples of which may be seen in the See also:watch-cases chased by G. M. See also:Moser, R.A. (1704-1783). The chaser first outlines the See also:pattern on the See also:surface he is to See also:ornament, after which, if the work involves bold or high embossments, these are blocked out by a See also:process termed " snarling." The snarling See also:iron is a See also:long iron See also:tool turned up at the end, and made so that when securely fastened in a vise the upturned end can reach and See also:press against any portion of the interior of the See also:vase or other See also:object to be chased. The See also:part to be raised being held firmly against the upturned point of the snarling iron, the workman gives the See also:shoulder or opposite end of the iron a See also:sharp See also:blow, which causes the point applied to the work to give it a percussive stroke, and thus throw up the surface of the See also:metal held against the tool. When the blocking out from the interior is finished, or when no such See also:embossing is required, the object to be chased is filled with molten See also:pitch, which is allowed to harden. It is then fastened to a sandbag, and with See also:hammer and a multitude of small punches of different outline the whole details of the pattern, lined, smooth or " matt," are worked out. Embossing and stamping from steel See also:dies and rolled ornaments have long since taken the See also:place of chased ornamentations in the cheaper kinds of plated See also:works.
