Oil-Stains
20.Three Kinds of Stain.—There are several kinds of oil-stain on the market, each of which is intended for a distinct purpose, and should not be confused with the others. The most distinctive types are:
1. Pigment-stains, which are mixed with a drying-oil, and are usually thinned with a solvent such as turpentine.
2. Preservative-stains, which contain pigments, and creosote, which is not a drying-oil. Frequently linseed-oil, and sometimes turpentine, heavy benzine, or benzine Japan drier are added to the mixture.
3. Volatile oil-stains, often called penetrating stains, which are usuallv made from oil-soluble coal-tar colors dissolved in a solvent such as turpentine, solvent naphtha, benzene, or benzol.
21. Pigment Oil-Stains.—Colors or pigments which are ground in raw linseed-oil were formerly much used as stains. They can be thinned with turpentine, or a mixture of turpentine and linseed-oil, or even with benzine with a little Japan drier and painted on wood with a brush. After soaking into the wood fibers for a few minutes, such stains should be wiped off and allowed to dry for several days before any other finishing is attempted. Vandyke brown, burnt and raw sienna, the umbers, ultramarine blue, and yellow ochre are examples of colors ground in oil that can be purchased at any paint-shop.
Asphaltum black, which is an asphaltum varnish, is another material that can be thinned with turpentine and used as an oil-stain. It is very permanent when exposed to light and is especially good as a stain for finishing cypress, as it produces a dark brown tone similar to mission-oak in color.
Dry pigment-colors do not dissolve well in turpentine, ' and are not as satisfactory when used as stains as are colors which are ground in oil.
Colors which are ground in oil are chiefly used at the present time as coloring-matter to mix with paints and are entirely suitable for that use. They produce more brilliant effects in paint than do dry pigment-colors, and keep the mixture more liquid so that it will spread better with a brash.
When dark pigment-colors are used with oil as a stain they have a covering effect instead of the pleasing transparency of water colors. These somewhat opaque results are just what are desired for silver gray or Jacobean stains, but are not pleasing for staining in general.
