wood bronzing

Breeding water glass solution is coated evenly with a brush objects made of wood, only then they sprinkle the golden bronze of the jars, which muslin cloth around the neck. Bronze after drying so much stick to the subject, that the surface of it, even mozhnootpolirovat agate. This method is recommended for bronzing frames for paintings and other items.

There is a simple way to the next, it is suitable for the preparation of the wax for waxing by wooden furniture. Take 100 g yellow wax good, finely cut it also add 12 g or 25 g of the mastic in the rosin comminuted powder. These substances put in an earthen vessel, and dissolving in the coals. When the whole mass melted, remove it from the flame and immediately topped up with 50 g of warm turpentine. All thoroughly mixed and poured into a tin or stone jar. In this form, the composition is stored until use. For polishing furniture take a small number of the composition of a piece of woolen cloth and rub the wood, which quickly becomes very beautiful and soft glow. Waxed furniture so very long retains a beautiful finish.

The liquid bronze, not giving the green color on the subjects of education verdigris, obtained by neutralizing the acids contained in dammar. To do this, proceed as follows: 250 g of finely grated dammar dissolved with frequent stirring 1000 parts of gasoline. Is then added 250 g of 10% aqueous sodium hydroxide solution, stirred for 10 minutes and allowed to move. Rapidly formed two layers: the upper containing resin solution in petrol, the bottom - the aqueous sodium salt solution with resin acids. Chief among them is drained, mixed with a new portion of 10% sodium hydroxide, allowed to settle and shaken. This top layer comprising a resin, wholly free of acids. Such a solution mozhnodobavit ¼ liter share of golden bronze, not fearing upbringing verdigris.

Abroad widely distributed the subsequent process of staining wood, having the advantage over the commonly used methods is that with this method wood is impregnated with dyes to a considerable depth can also be polished without spoiling applied paint. The method is as follows. After preparing the batter made from rye, wheat or potato torture, smear it on a sheet of paper, cardboard or thin tin layer thickness of 0.5 mm. This paint layer is applied in powder form or in semi-liquid state in which they are used for preparation of colored paper, which after all is applied to the object to be coated; on top of paper or cardboard are placed perforated tin sheet and tightening the brackets. As such, all immersed in boiling water. There dyes are dissolved and impregnated wood, only the dough hardens so firmly that holds a number of superimposed paint, not allowing them to merge with each friend. Thus it is possible to paint the log immediately in different colors, not allowing the crowning merge; It can be applied to the veins, pictures and etc. all kinds of colors. Should penetrate deeper into the paint timber, the longer you have to hold items in hot water. After the dyeing process, the dough is washed off with water and give the painted surface to dry thoroughly in a dark place. Instead of the direct use of dry powder paints, which are suitable for each kind of ink that are used in the dye class, you can also use another, more affordable way, it consists in the fact that the pre-impregnated with paint and sawdust and already they are applied the above method to the batter.

Shoe gilding, especially on a log, requires very careful handling. Previously with gilding to be swept away by all the small dust, then gently wipe the gilding with a soft sponge, even better with a piece of cotton wool slightly moistened with wine alcohol or turpentine. Instead, these liquids are used similar good strong beer, the so-called solution of Marseilles soap or a hodgepodge of 10 elements of ammonia and 40 parts soap spirta.Horoshim cleaner gilding considered similar to egg whites, which gently wiped the subject with the help of a piece of flannel. You can use a hodgepodge of proteins (2-3 eggs) with 18 g of water zhavelevoy; this liquid mixture with a soft brush gently wipe the gilding, especially the tarnished place. Finally, the same goal can serve a pure wine vinegar, which is covered by gilding a soft brush, sponge or piece of stalemates. After 5 minutes, the vinegar gently rinsed with clean water, not wiping anything.

To clean the gilded bronze in addition to ammonia, diluted with water, good results alienates even the subsequent process: gilt wipe all pre-moistened with water with a brush. Then coated with a soft brush with a mixture consisting of 60 elements of water, nitric acid 15 elements and two elements of alum, after which the liquid is allowed to dry, it does not wiping.

The following can be considered the best of the many compositions:

1) 25 weight elements finely planed stearin is added to 12.5 parts of turpentine and the mixture is heated until dissolution filled with stearin.

2) to dismiss the 25 elements of the wax in glazed pot and then, at what time the wax bloom, CNI-toil vessel with a flame and the wax is added to 40 parts of turpentine.

3) The heating elements 10 copal varnish is added to it 40 elements wax and at what time crowning bloom, made up, gradually stirring, 75 elements of turpentine.

4) 30 elements wax and rosin dissolving 1.5 elements on the fire, and then, removing the vessel from the heat, add 14.5 elements of turpentine.

5) At the 30 elements of water take 2.5 elements potash, and boiled, and later by the addition of 5 elements finely planed wax and heated the entire mixture until a homogeneous mass of soap.

Varnish is selected for the color shade of the polished wood, respectively, from reddish-brown to snow white, or rather colorless. The desired shade is obtained if we take in different proportions two main polish.

Bleached shellac makes the preparation of the ordinary as follows: 4 weight components of shellac are mixed with 1 part baking soda and dissolved with stirring in 15 parts of water until the complete dissolution of the resin, ie, until the liquid does not become completely transparent. Then allowed to settle and decanted clear solution without settling into another bowl. Here a clear solution, a solution of 4 weight elements of bleach in 4 parts by weight of water and left a hodgepodge of inaction on a couple days. Thereafter jumble slowly poured into hydrochloric acid, before the stand no longer sucks resin. Then there is only good to wash the sludge resin with water to remove traces of hydrochloric acid, and dried.

In recent years, it is time to aniline dyes gradually replaced all the old paint plant due to low cost and easy way to use.

As is known, the etching of the log up until now are solutions of organic dyes in water or an alcohol. Such a tool has, however, one significant flaw: the surface to be painted logs from alcohol or water is rough, so that after etching it is necessary to smooth glass skin, and such polishing is erased in some places paint job as there is a need in the other surface, which entails a new grinding and so on, until you have a perfectly smooth surface. Patented by "Yungas" in Württemberg mordant is that instead of alcohol or water paint solvent is turpentine. With the use of such mordants wood fibers did not swell, thereby excluding the appearance of roughness, just so, and the need for sanding. Looking for a tree structure, a thin or coarse, it is sufficient to couple one or coatings to achieve the desired shade. Sami solutions under the walnut, rosewood, Radiant or gloomy oak and etc. prepared by conventional means with water or turpentine substitute for alcohol. Thus, to obtain good stain under the walnut tree was dissolved 600 g of brown paint and 15 grams in 1 liter of orange turpentine. Then the filtered solution was added thereto and the filtered solution of 100 g of black ink in 3 liters of turpentine. If the resulting stain would be tough or inappropriate desired tone, it is diluted with turpentine.

Good stain giving very beautiful shades on wooden heads of tubes is prepared by grinding in water of equal parts of potassium dichromate (potassium bichromate) and oxalic acid. When the evolution of gas from the liquid stops, a mordant is ready. It can continuously take care in a well-sealed bottle. The stronger solution, the color becomes darker wood. If one or immersion coating is insufficient to achieve the desired color density, then one must repeat the operation. This same mordant can also consume other similar wooden products.
