The gold is prepared for painting on a tile kept expressly for the purpose, and which must not be used for any other paint. Place some of the gold on the palette with your palette-knife, and mix a little turpentine with it by dipping your palette-knife in the turpentine and rubbing down the gold with the turpentine on the knife. If more is needed, again dip your knife in the liquid, and do so as often as it is necessary; but you must use the utmost care not to have the gold too thin; gild with it as stiff as it can be smoothly applied. Should any gold remain on the palette after the gilding is finished, mix in a little turpentine and scrape it all up with your palette-knife, then replace the gold on the square of glass. Silver is used the same as gold. The bronzes are for handles and conventional flowers or figures; they are rich and pleasing in effect. PURE GOLD cannot be employed for gilding plain white china. It also comes on a little square of glass and is used for gilding over colors. It can be applied over any mineral paint or relief, and may be polished or burnished as desired. This gold is mixed with turpentine, for use in the same manner as mat gold. RELIEF. The best is mat relief, which comes in a powder, and is used for both tube and mat colors. It is prepared by mixing with a very little fat oil and turpentine, and should be applied stiff enough to make a raised line. It is useful where a small raised surface is desired, as on the edge of a leaf or the petals of flowers. A fish-net is much more effective if the gilt be put on over the relief. Should the relief dry and become too stiff while using, soften it from time to time with a little turpentine, always using the horn knife for mixing, as the steel knife should never be used with the relief, and the relief must always be fired before the gilt is applied. Enamel white can be mixed with delicate tints, turpentine, and a very little fat oil for raised flowers; or the white alone may be used for pearls, imitation of lace, or embroidery, but its use is limited and it will not stand two firings, so should always be the last paint applied. MAT COLORS are for Royal Worcester decorations. They come in powders, and when mixed with a little oil and turpentine are used in the same way as the Lacroix tube paints. BOX FOR MATERIALS. Select a light wooden box, or one of strong pasteboard; have the box of a convenient size to contain all your painting materials. PIECES OF SOFT, OLD MUSLIN, torn in different sizes, and plenty of them, are very essential for cleaning brushes and rubbing paint off the tile or china; the demand for clean pieces will be constant while painting. CHINA. Have this of the very finest French ware, without spots or other imperfections of the surface, and never attempt to decorate china after it has been used, for it seldom proves satisfactory. =A Monochrome Painting.=
