Here are the recipes Chinese ink.

1st recipe:

This simple method makes it possible to obtain mascara that is not inferior in quality to real Chinese mascara.

In lamps that have very little air flow and, therefore, strongly smoky, kerosene or refined turpentine oil is burned. The rising soot is passed through a zinc pipe, at least 5 m long, and installed with a slight upward slope. The soot deposited in the pipe sections closest to the lamp is most suitable for making not particularly high-grade inks, such as black printing ink, while the soot deposited in the more distant sections of the pipe, due to its fineness and purity, is very suitable for making good ink . But even this soot contains some resinous substances that must be removed.

To remove resinous substances, mix the finest soot in a large porcelain cup with a glass or porcelain stirrer with such an amount of nitric acid that a thick dough is obtained; the latter is diluted with a small amount of distilled water. After that, the cup is gently heated until dense fumes of nitric acid begin to be released. Then water is added, the mass is allowed to settle, and the acidic liquid is drained from the black precipitate, after which the above is repeated again to remove the remaining acid. The soot washed in this way is boiled with a strong solution of caustic soda for half an hour. Caustic soda contributes to the complete destruction of all resinous substances; after treatment with caustic potash, the soot is thoroughly washed several times with water, after which it is dried in closed vessels over a fire, then mixed with a completely transparent solution of gum arabic and the mass is evaporated by heating to such an extent that upon cooling it turns out to be a completely hardening dough.

Remove the cup from the fire, add to the coal mass a small amount of musk, previously dissolved in strong wine alcohol, and allow the mass to dry. As soon as cracks begin to appear on the mass during drying, it is pressed into metal molds in the form of tetrahedral sticks, equipped with Chinese written characters on the inside, and allowed to dry completely in the air. At the end, cracks and crevices are filled with the same mass and the sticks are partially or completely covered with tinsel sheet gold or silver.

2st recipe:

In an enamelled iron cauldron fitted with a tightly fitting heavy wooden lid, 50 wt. hours of soft water (distilled or rain), dissolve in it 3 wt. hours of crystalline borax and then mixed into a continuously boiling liquid in small portions of 4 wt. h. completely clean (wax-free) bleached ground shellac. When complete dissolution occurs, a sample is taken into a glass tube, cooled quickly and observed whether the solution remains transparent or whether undissolved particles still float in it, which in this case gradually accumulate on the surface of the liquid and form a thin layer. If this phenomenon does not occur, then the solution can be put into operation, otherwise the wax must be isolated. For this purpose, the fire is reduced, the cauldron is covered with a wooden lid, on which stones and other weights are placed, and allowed to stand for 14 hours.

After this time, the lid is removed, all wax floating on the surface of the liquid is removed, and the solution is carefully scooped up into a wooden vessel. Often at the bottom of the boiler there are still particles of wax in the form of a cloudy mass, which is collected in a separate vessel and then filtered. Scooped up liquid is carefully filtered through the filter, even if it seems transparent. The wax is washed with water, the water containing shellac is collected and used to prepare a new solution. All the collected wax is boiled down with water, after cooling it is removed, and thus it becomes suitable for any other purpose or for sale. A transparent shellac solution is mixed with the finest soot with such an amount of solution that a mass is obtained in the form of a liquid slurry, which is subjected to repeated grinding in a paint grater.

The amount of carbon black added (approximately 5 parts by weight per 100 parts by weight of the solution) depends on the degree of its fineness. An extremely finely ground mixture is gradually mixed with the necessary solution of borax and shellac, mixed well and filtered through a very dense cloth in order to retain grains that may still be contained in it. At the end, add a few drops of carbolic acid and mix thoroughly.

Inferior grade ink is prepared from ordinary oven black, which is boiled in caustic lye, then allowed to settle in a large vessel of water, washed several times in water and mixed with a solution of gum arabic. Subsequently, they are prepared in the manner described above.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Power supplies 3Logic R-Senda for powerful mining farms 20.08.2018

3Logic introduced special R-Senda mining power supplies with increased power from 1600 W to 2400 W. All of them are characterized by an improved component base and more efficient cooling. In addition, the units are now designed with more reliable 16AWG cables to ensure long and trouble-free operation of the system under continuous maximum load.

Regardless of the model, all power supplies are equipped with a large number of 6 + 2-pin connectors for video cards. For example, in the maximum version of the block at 2400 W, their number reaches 12. It is worth noting that honest powers are declared for the blocks. For 1600 W, the current limit for 12 V lines is 133 A, for 2000 W - 162 A, and for older models with a power of 2400 W this figure reaches 200 A. R-Senda products are characterized by high efficiency, reaching 92%.

The range includes both ATX form factor power supplies and models for installation in 1U cases. The warranty period for R-Senda products is one year.
