A method of finishing such metals as brass, German silver, etc., which if well done, gives a very handsome appearance to the work. The work must first be carefully finished so as to have no scratches, as these would show through the curling and destroy the effect. After the metal has been finished with fine files, emery paper, Water-of-Ayr stone, and finally the finest rotten stone applied by means of a buff, the curling is produced by means of a stick of charcoal moved in circular sweeps over the surface, which should be kept well moistened with water. After the desired effect has been produced, the metal is lacquered.
We have seen "curling" applied to surfaces of considerable extent, but in such cases the effect never seemed to us as good as in the case of very small articles. If the sweeps are large they give a coarse appearance to the work, while a large surface covered with small sweeps has a confused appearance.
