Here are some recipes artificial pearls with celluloid varnish.

1st recipe:

Instead of pearl essence for rough crafts, you can use the so-called silver leaf, which is ground with a gelatin solution or celluloid varnish. You can also use crushed mica. To do this, mica is roughly crushed in a mortar, and then ground very finely in a paint grinder, after which it is sifted through a fine sieve.

2st recipe:

You can put a layer of silver on the beads. To do this, dissolve 10 g of lapis 200 g of distilled water and add ammonia dropwise until the resulting turbidity dissolves and the solution becomes transparent. Separately dissolve 2,5 cm3 of formalin (40%) in 100 g of distilled water. Both solutions are poured together and clean and dry glass beads are immersed in them. When the balls are covered with a silver layer, they are taken out, rinsed and dried. After drying, they are covered several times with matte celluloid varnish.

3st recipe:

A. Pussolli's method gives good results and is much easier to implement than a number of other methods. This method is carried out as follows.

The gelatin is allowed to swell in water, the excess water is drained and dissolved in a water bath. Ammonium bromide is added to the resulting solution in an amount of 5% by weight of the taken gelatin. Glass objects are immersed in the resulting solution and allowed to dry. (You can also pour this solution onto a marble or glass table and further process the resulting layer yourself. You also need to pour this solution into molds.) After drying, objects are immersed in a diluted aqueous solution of silver nitrogen salt (lapis). The solution is prepared by dissolving 2 g of lapis in 1 liter of distilled water. Then they are dried again, then the dried objects are immersed in a diluted solution of collodion in a mixture of alcohol and ether.

The approximate content of nitrocellulose in this solution should be 1,5% (collodion is a solution of nitrocellulose - pyroxylin in a mixture of alcohol and ether). After drying, the surface of the film, due to salts opalizing in gelatin, gives a good iridescent color. Instead of ammonium bromide, potassium bromide or ammonium chloride can be used. Instead of silver nitrate, you can use other soluble silver salts, as well as water-soluble mercury salts (mercuric chloride and others).

In addition to silver and mercury salts, bismuth salts can be used: this includes, for example, the German method in which a gelatin gruel is impregnated with an alcoholic solution of bismuth trichloride (bismuth trichloride). Instead of gelatin, celluloid and acetylcellulose can be used.

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 ... >>

museum allergy 10.03.2010

A survey of about a hundred employees of the National Museum of Poland in Warsaw showed that more than 70% of employees suffer from allergies in the form of a runny nose, conjunctivitis, skin rashes and asthma attacks.

In a third of cases, symptoms appear only at work, and tests have shown that fungi that start on museum exhibits are the main cause. According to doctors, the ventilation system in the halls is weak, which can be dangerous for the health of visitors.
