Ebony imitation mordant. Simple recipes and tips
Directory / Factory technology at home - simple recipes
Comments on the article
Smoothly planed black (ebony) wood has a pure black color without gloss and has such a fine grain structure that the latter cannot be seen with the naked eye. The proportion of this tree is very high. Ebony is polished so well that its polished surface is like a black mirror. In order to achieve a good imitation, one should take dense, hard varieties of wood with a delicate structure. This condition is satisfied, for example, by beech and pear trees.
Here are some recipes mordant to simulate ebony.
1st recipe
Items with carefully ironed surfaces are etched with sulfuric acid, after which they are washed with water and dried. After treatment with this acid, objects are etched with a logwood solution or iron mordant.
In the first case, having prepared a 10% solution of logwood in water, they cover objects with it, then allow them to dry and then treat them with a 1% solution of potassium dichromate in water.
In the second case, iron mordant is used, which is prepared as follows: old iron is treated with strong vinegar for several weeks, taking 1 parts of vinegar for 10 weight part of iron. Then boil 1 weight part of ink nuts with 10 weight parts of water. The object to be painted is placed for several days in the resulting solution of iron acetate (1st solution), then dried in air, after which it is also placed for several days in a decoction of ink nuts. If the object is inconvenient in its size to be immersed in a liquid, then it is treated with a brush several times with a decoction of ink nuts until a dark yellow color is obtained and then covered with a solution of iron acetate or a solution of ferrous sulfate until a black color is obtained. In both cases, the operation is carried out until the color of the desired density is obtained.
It is even better to cover the object alternately with an infusion of ink nuts, then with an infusion of iron acetate or iron sulfate, and each time you need to let the surface of the object dry and then cover it again.
2st recipe
An extremely beautiful black coloration of wood can be achieved by treating it with black aniline dye nigrosine, which dissolves in water. For this purpose, 8 parts by weight of nigrosine are dissolved in 10 parts of water and the object is covered with this solution. After drying, a solution of copper in hydrochloric acid is applied to it, which is prepared from 20 parts by weight of hydrochloric acid and 1 part by weight of copper. Immediately after applying the copper chloride solution, the wood takes on a beautiful matte black color, very similar to the color of real black (ebony) wood. Polishing gives it a strong shine.

Machine for thinning flowers in gardens
02.05.2024
In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers.

Advanced Infrared Microscope
02.05.2024
Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>
Air trap for insects
01.05.2024
Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>
| Random news from the Archive Runway LEDs
21.08.2009
The field of application of LEDs is expanding: at one of the Paris airfields, they replaced halogen incandescent lamps in signal lights leading the aircraft to the runway.
New light sources designed specifically for this purpose consume 11 times less energy and last much longer than halogen lamps. At a large airport, where the number of signal lights reaches tens of thousands, the savings in electricity and maintenance will be large sums.
