Fig. 117.—Another Example.
In this case, a material such as "Matsine," or "Scumblette" is applied by spraying over a different coloured ground, and, while wet, this is "flogged," or a dry brush is drawn over the surface, removing hair-like parts which expose the ground colour beneath. Thus a very dark green or even black may be used over a white or nearly white ground, or a very dark red over an orange chrome ground. Various metallic effects may also be produced on wood or other materials by using silver, aluminium, gold or copper leaf, and partly spraying over it a lacquer of suitable colour.
The actual graining can be done in the ordinary way by an expert artisan, but as a rule this would be too costly when perhaps thousands of iron or other goods are to be turned out in a short time. In such a case transfer graining paper is sometimes employed, but this also is somewhat costly. Bellamy's graining rollers are found to be very economical. This tool consists of a cylinder on the outside of which is engraved the grain of various woods, such as oak, mahogany, maple, satin wood, birch, walnut and ash. All that is necessary in working it, is to pass the roller over the surface immediately after the graining colour has been applied, when it will be found to remove some of the paint and give the appearance of graining. This appearance is considerably enhanced if the parts are softened after the roller is used by going over the work with a badger softener.
Marble Grounds.
For the convenience of those who are called upon to imitate marble for any class of work, the following information is given as to the colours to be employed for the ground colours.
White.—A dead white ground should be used mixed to dry hard and smooth.
Sienna.—White blended with a mixture of white and raw sienna in irregular patches.
Pink Marble.—The ground may be the same as that used for sienna, but a little Venetian red should be added to give it a pinkish cast.
Alabaster.—Light cream ground made by adding a little middle chrome and vermilion to white.
Rouge Grotte.—This is a very beautiful marble which contains a large number of different colours. The ground may be either white or Venetian red, mixed with a little chrome yellow.
