The Improving And Preparation Of Furniture Wood In French Polishing
For a French polisher, who is considered a good worker, he should have used other than his usual ability to put on a good polish, a thorough knowledge of different types of wood for furniture, as well as bring the most approved method.
To the full extent of their natural hues or tints; Should he be able to improve the lower wood species and color, to perfect the bleach or one of the fantastic materials whose art is applied in a manner that will bring the greatest perfection.
For a better knowledge of the processes above the following information is given.
Improving.
Iron filings added to a decoction of gall nuts and vinegar give ebony iron, the intensity turned black after brushing on once or twice.
Walnut or badly colored rosewood can be improved by cooking a half-shell extracted from the ounce of nuts and the same amount of cachou in a liter of fresh water, and applying with a sponge.
A half pound of nut shells and a similar amount of oak bark, which is cooked in a liter of water is many produce the same result.
Mahogany can be improved by rubbing it with red powder chalk (Ruddle) and a woolen cloth or first wiping the surface with liquid ammonia and subsequent Rotölung.
For a rich soft red color, rectified spirits of naphtha, dyed with Camwood dust or oily decoction of Alkanet root. Methyl alcohol and a small amount of dragon blood also produce a mild red.
Each yellow wood can fustischen by an alcoholic solution of Persian seeds, turmeric or Gamboge be improved. An aqueous decoction of barberry serves the same purpose.
Birch, if one prefers a warm hue can with oil, very slightly tinted pink-grass or Venetian red sponge; The greatest care must be, or it is unnatural in appearance, becomes red.
Maple, which is a dirty brown color or a cold gray color and mahogany, ash, oak, or any light wood can be lightened by liquid bleaching.
Many materials can be improved with the help of raw linseed oil, mixed with a little turpentine. Artificial grain can be given different woods by a stalk of camel hair and crude oil; Must be applied two or three layers, and after a while, the soil must have a layer of oil, which has been diluted with a lot of turpentine, and then rubbed.
Matching.
Old mahogany furniture, which has been repaired can be easily adjusted by wiping the new parts with water, in which a lime of dissolved lime, or by soda and running water.
The darkening agent for general use are colored oils, newspapers, Aqua Fortis, iron sulphates and silver nitrate, with exposure to sunlight.
For new furniture in oak, ash, maple, etc., the process of adaptation requires care and skill.
If it is desirable to make all parts in a piece of furniture with a unique tonality or color, you bleach the dark parts with a solution of oxalic acid, which is dissolved in hot water (about two Pennyworth of acid to One liter of water) Powerful solution); Once dry, if that was not enough, apply the white patch paired delicate or light parts to be oiled.
In order to preserve the nuances they are covered with a camel hair stem with white paint.
On many forests soda ash and potassium dichromate are very effective also dark, as well as other preparations of acidic or alkaline nature, but the above two are the best.
A good method of preparing these obscuring devices, called the "French Polishing Manual," an excellent little work which has been published at Perth for several years, is to procure two carbonates of soda powder and dissolve it in a half- Liter of boiling water Then finish three bottles and label them one, two, three.
In one half of the solution and the other two each half a gill At number two you add an extra gauge of water and three Then, you get the same amount of bichromate of potash, and prepare them in a similar way, then have six dye liquids to acquire a series suitable for almost all classes of wood Brown and dark tones.
The bichromate of potash is useful for darkening oak, walnut, beech or mahogany, but when applied to the ash, it renders a greenish mold.
When a nut of sherry piece is in solid veneer or should be used to darken it to match the base color, then fill the dark marks with a pen and black stain.
Carbonate solutions are generally for such dark surfaces. Like rosewood, used and an even darker hue can be given to each by oiling after drying the patch.
The best way to use these chemical spots is to get into a saucer so much as it serves the lens, and it is quickly with a sponge, which is rubbed quickly and evenly on the surface, apply and dry 5 immediately to dry Old cloths.
Dark and light parts between which the contrast slightly, can be adjusted by painting the old and the blackening of it with oil, which should stay on it long enough; In this way, the different sections can often be made so that they are together, without bleaching or dyeing.
Painting.
The next process is painting.
It often happens in cabinet work that a defective space is only discovered after cleaning; The ability of the polisher is necessary to paint to adjust the other. A box that contains the following powdered colors is found very useful, and if necessary for use, it must be mixed with the French Polish and applied with a brush.
The pigments are best suited: Black fall, raw Siena, raw and burnt umber, brown Vandyke, yellow French from Naples (remember this is a very opaque pigment), cadmium yellow, Krautkarmin (these are expensive ) And light or Venetian red;
Before mixing the colors should be finely beaten. However, the painting method this objection for the best class of furniture that the effect of time will darken the body of the piece of furniture, while the painted part is almost over remain its original color.
The primary work should therefore place these varnish pigments or colored paints are applied.
Dyed Polishes .
The processes of staining of varnish or paint are as follows: for a red, put a little alkane root or camwood dust in a bottle of varnish or paint; For a bright yellow, a small piece of aloe; For yellow or Gamboge yellow turmeric; For a brown, baking soda and a very small amount of dragon blood; And a black, a logwood some chips, gall nuts and copper, or by adding black gas.
Aniline dyes (black excluded) are very important for dyeing agents that are useful Turkey-red, Sultanrot, purple and brown polish.
A small part is placed in the varnish that dissolves quickly, and no effort is required.
The best way to buy these dyes is by the ounce or half ounce. The penny packages of chemists sold are too expensive, although a little goes a long way.
