 358 IRON with the lettering done in some differently coloured enamel. A modification of this class of coating has been recently introduced by Dode, metallic platinum being mixed with the enamelling com position so as to &quot; platinize &quot; the metal and thus add to the dura bility ; according to the inventor, the comparatively high price of platinum does not interfere with the applicability of the process, one platini/hi&quot; application costing no more than three coats of good paint, and only about a tenth of the expense of nickelizing.
