If the zinc is the metal tobe inlaid, zinc dust is the powder employed. When thearticle has obtained the desired depth of inlay and onlay,it is allowed to cool and then removed and brushed witha stiff brush to remove the stopping-off useful type of furnace for this class of work whenusing the zinc-dust vapour process is shown in Fig. 0,and a specimen of the results obtained in Fig. 7. The vapour process enables a variety of effects to beobtained and a number of metals to be blended together. Fig. 7.—Copper panel inlaid with zinc. which hitherto has been impossible, and alloys of manycolours and tints to be obtained in the one thickness and depth to which the metals are tobe inlaid and onlaid can be controlled at the will of theoperator. Tliis vapour process of burning in and blendingmetals enables very beautiful colour effects to be obtained,the colours ranging from silver-white to yeUow brassand bronzes of various shades graduating to red great charm about this new process of inlaying metals,and one that is unique, is that the inlay has not the sharpline of demarcation essential to damascening and similarprocesses, but a soft transition from the inlaid mctafto the surrounding metal. For instance, in the caseof inlaying zinc in copper, the zinc is surrounded by aband or halo of a golden-coloured alloy. This processof inlaying is not confined to zinc and copper ; it hasbeen successfully applied to such metals as nickel, cobalt,antimony, and alumini
