The silversmith's handbook : containing full instructions for the alloying and working of silver, including the different modes of refining and melting the metal; its solders; the preparation of imitation . and attained to a higher standard than it everbefore possessed. The art of stamping and shapingarticles of jewellery from sheets ofthe various metals came into generaluse just previous to the first Exhibi-Die. tion in 1851. These, which are made in considerable numbers, are produced by means of dies, having the shapeof the pattern upon them,both at the top and bot-tom, made of hardenedsteel. Fig. 37 representsa bottom die for the use ofthe stamping press, andFig. 38 represents the raising the metal bystamping, the material un-dergoes the same bendingsand extensions between thedies as if it were beingmanipulated by the ham-mer, and consequently itrequires to be repeatedlyannealed, otherwise itwould crack and fall topieces in a subsequent operation. The raising. iiiiiiiiiiiuiiiiiiiiiiiiiiiiiiiiiiiiniiiiiiiiii ^lllllillllll|lll^nmlKi) F\g. 38. Stamping Press. STAJMPING PRESS. I 33 should be brought about gradually, and this is doneby placing a number of sheets of metal between thedies, which prevents the top die from falling withtoo sudden an action upon the metal, which itwould do, as. it falls with a succession of forces ifthe process be repeated, and if its action be notarrested by the means we have pointed out. Afteievery blow of the stamp one of these pieces isremoved from the bottom, and a fresh one addedat the top; the continual falling of the stampgradually forces these plates, if placed in themanner we have indicated, to take the shape of thedie. The exact form of the figure is effected bystriking the plates singly between dies whichexactly correspond. A very large quantity ofwork is now produced by the means we havestated, such as brooches, studs, locket-backs, ear-rings, rings, and an endless variety of otherthings; moreover, by the
