Skin apertures. Simple recipes and tips
Directory / Factory technology at home - simple recipes Liquid dressings for skin are colored, saponified aqueous solutions of various resins, which are applied to the skin with a sponge or brush and after drying give a good gloss. Properly prepared dressing, giving the skin shine and elasticity, should not be afraid of dampness. For the most part, bleached, freed from shellac wax, shellac is used in dressings. If ordinary shellac is used, then it is useful to first get rid of shellac wax, which negatively affects the gloss of the finish. For this purpose, an alcohol solution of ordinary shellac is left alone in a closed boiler for several days to separate the wax, after which the solution is carefully drained from the precipitate, and the alcohol is removed by distillation. Skin dressings The utensils in which the dressing is prepared should be copper, well tinned or enamelled, but in no case should iron utensils be used. For black dressings, a mixture of blood and milk, albumin, gelatin and other substances, colored with appropriate dyes or kampesh extract with iron salt, is also used. For dressings, aniline dyes are used that do not change their color in an alkaline environment. Use rainwater or distilled water, but in no case should you take hard water. In order to make an aqueous skin dressing resistant to frost, denatured alcohol (approximately 10%) is added and the amount of water is reduced accordingly. Skin dressing
Dissolve shellac in ethyl alcohol and add the remaining substances. High gloss finish for leather
Dissolve shellac with low heating in a water bath in a solution of ammonia in water. Aniline black is added to the resulting solution and mixed well. More water is added if necessary. Finish for colored skin
Melt the wax and add the remaining parts while stirring. Finishing for hard leather and leather goods The preparation of this appretura is as follows. On a water bath, gradually heat up 0,75 liters of 95 ° wine alcohol and add 250% shellac of the highest grade. Heating is continued until the final dissolution of the shellac. At the same time, in another vessel, 250 g of nigrosin soluble in alcohol or (if we mean colored skin) aniline paint slightly soluble in alcohol are dissolved in 5% alcohol of wine and both solutions are poured together. To the resulting mixture is added, stirring, another 50-100 g of wine alcohol and a small amount of turpentine or styrax; when everything is dissolved, let it cool. To avoid strong volatilization of alcohol during the preparation of the solution, the liquid is placed in a closed tin vessel and placed either in warm non-boiling water or in the sun, and the vessel is covered with a loose lid. Ready dressings are stored in a tightly closed vessel in a cool place and, when used, are applied several times in an even layer, using a sponge, and the skin must first be well cleaned. Shellac finishing for black leather
Shellac finish for skin No. 2
The preparation of the dressing according to the above recipes is carried out as follows: Borax is dissolved in an enamel bowl in boiling water. Then, well-ground shellac is gradually added in small portions, and new portions of shellac are added only when the previous portion has dissolved. This is very important, because if you add a very large amount of shellac at once, you will get lumps that will then be difficult to dissolve. To replace the boiled water, add the same amount of hot water. When all the shellac has dissolved, then when using unrefined shellac, the solution is allowed to cool and after a few days the solution is drained from the released shellac wax. When using bleached shellac, the hot solution is allowed to cool to 70 °C. Having thus prepared a shellac solution with borax, the remaining components are added with stirring. To preserve the dressings, formalin (or thymol) must be added. It is useful to filter the finished dressing and then pour into bottles. Soap finish for skin
The mixture is boiled until completely dissolved in 2,5 liters of water. During cooking, stir and add water to replace the evaporated, maintaining a volume of 2,5 liters. Shake until a homogeneous emulsion is obtained. black finish
During boiling, wax and potash are heated in 1,5 liters of water until a uniform wax milk is formed, which, when standing, should not release wax on the surface. At the same time, all other parts are dissolved in another vessel in 7,5 liters of water. With strong stirring, wax milk is added to the 2nd solution; the mixture is heated until the sample taken, when cooled, shows complete homogeneity and a drop of the sample on white paper, after drying and grinding, does not give a strong shine. It is useful to add 15 g of formalin to the dressing to prevent mold. Brown wax finish for leather
Melt the wax and add the remaining parts while stirring. Black wax finishing
Mix all parts with low heat until a homogeneous mass is obtained. After applying the mass to the skin, polish with a soft brush. Finishes made from glue, casein, milk, blood, sugar Dextrin and vegetable mucus are simpler dressings. These substances are weakly resistant to the influence of the weather. By adding resinous substances to these dressings, it is possible to improve their quality and enhance their brilliance. Here are some recipes for such appretura. Blood Appretura
Kampesh extract is dissolved in a small amount of boiling water and diluted with 5 liters of cold water. Vitriol, previously dissolved in cold water, is added to the solution. Finally milk, blood and the rest of the water are added. Finish for colored skin 1st recipe:
Crushed flaxseed is boiled for half an hour in 5 liters of water. Then filter through filter paper and cool. Albumin is dissolved in water, after which both solutions are mixed, milk and water are added. 2st recipe:
Melt the wax in a water bath and add turpentine. Separately dissolve soap in water and mix both solutions. The mass is ground in a mortar until a homogeneous paste is formed. The mixture is tinted in any color with aniline paint dissolved in alcohol (5 g of paint per 25 g of alcohol). 3st recipe:
Add paint as above. 4st recipe:
Melt the stearin and add all other parts. Dissolve the paint separately in alcohol. Author: Korolev V.A.
