If all that is claimed for the process invented by two Italians named Marino bo true, there is likely to be something of an upheaval in the cheap jewellery and fancy goods trade, and a- revolution in the art of electro-plating. They claim that by this process they are able to deposit any metal upon any other, upon porcelain or glass, or in fact, upon any solid. There is likely to be- quite a demand on such things as tumblers, finished off with silver stripes or bands, glass fruit dishes similarly decorated, and silvered porcelain tea* pots. .In order to do this the-surface '* of the glass or porcelain would be first roughened by a sand-blast, so as to-be in a suitable* condition to take and hold the metallic deposit. The surface is then painted with a mixture of,a'.metallic <salfc and hydrofluoric acid, when it w ready for treatment in the, special electrolytic solution. 'Full particulars of the method, beyond those outlined, have not ; yet ' been given, but should it be capable of doing all,that is claimed for it, it is probable that much will be heard of it in the near future. ■'-.' • ,- " «
