Wood stain is a type of paint used to colour wood.It consists of colourants dissolved and/or suspended in a vehicle or solvent.Vehicle is the preferred term, as the contents of a stain may not be truly dissolved in the vehicle, but rather suspended, and thus the vehicle may not be a true solvent.
Chemical staining of wood is rarely carried out because it is easier to colour wood using dye or pigmented stain, however, ammonia fuming is a chemical staining method that is still occasionally used to darken woods such as oak that contain a lot of tannins. Staining of wood is difficult to control because some parts of the wood absorb more ...
The material that is trapped coats the underlying material, and the stain reflects backlight according to its own color. Applied paint, spilled food, and wood stains are of this nature. [5] A secondary method of stain involves a chemical or molecular reaction between the material and the staining material. Many types of natural stains fall into ...
Ammonia fuming is a wood finishing process that darkens wood and brings out the grain pattern. It consists of exposing the wood to fumes from a strong aqueous solution of ammonium hydroxide which reacts with the tannins in the wood. The process works best on white oak because of the high tannin content of this wood.
There are basically two types of wood graining: coarse (rustic) and fine (polite). In fine graining, layers are built up using water colors and finished with an oil glaze made of varnish, linseed oil and mineral spirits. Water colors use a beer solution tinted with a pigment, Indian inks, or Vandyke crystals dissolved in water.
One of the most important is the workability of the wood: the way in which it responds when worked by hand or tools, the quality of the grain, and how it responds to adhesives and finishes. [10] When the workability of wood is high, it offers a lower resistance when cutting and has a diminished blunting effect on tools. [10]
