Here is the recipe enameling iron.

Crushed glass 3,5 kg;
Purified potash 1 kg;
Potassium nitrate 1 kg;
Borax 0,5 kg;
Minium lead 5,25 g

Grind the ingredients to a powder, then mix and melt in a refractory crucible (which must be perfectly clean). First, a very strong swelling will occur, and then the mixture will melt and turn into liquid glass.

A molten liquid is poured onto an iron plate, previously moistened with water, which is cooled with water. Then the mass is ground into a fine powder and kneaded with water on a glass plate into a thin paste, which is applied to the object to be enameled.

After drying, which proceeds very slowly, the object is placed in a muffle furnace, where, within a few minutes, the enamel melts uniformly without any bubbles, but with the formation of a shiny lining.

To give the enamel a more beautiful pale blue hue, it is recommended to add 300 g of nitrogen-cobalt salt to the above mixture.

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 ... >>

transparent paper 22.03.2013

The Japanese companies Oji Holdings and Mitsubishi Chemical Corp. managed to obtain the first samples of transparent paper, the joint statement of the enterprises says. The invention of transparent paper will pave the way for flexible screens and displays that, using the properties of paper, can be folded into a tube, unfolded like a roll of paper, and folded like a sheet of newsprint.

Externally, the obtained samples are indistinguishable from a transparent polyethylene film. The main difference is in the composition. The transparent paper is made from cellulose nanofibers, which are only one 20th of a human hair thick. Paper is lightweight, flexible, and environmentally friendly as it is easily recycled and does not harm the environment.

The developers expect that their product will be able to eventually replace glass, for example, on tablet computers. In the future, this will pave the way for the creation of flexible tablets, screens and displays that, using the properties of paper, can be folded into a tube, unfolded like a roll of paper and folded like a sheet of newsprint.

The weight of the thinnest of the experimental sheets is 8 g per square meter, the densest is 85 g per square meter. Both companies intend to begin industrial production of transparent paper within three years.
