Fascinating chemistry

Over time, metal parts lose their attractive appearance and become completely or partially covered with rust. But they can be “rejuvenated” using galvanization and without much expense. We securely attach pieces of copper wire to the rusty parts and

Copper-plated surfaces are aesthetically attractive and well protected from adverse external influences. If it is a non-metallic surface, then it additionally acquires electrically conductive properties. With the practice of copper plating at home

The need for copper plating of metal surfaces at home is associated with certain technical or aesthetic needs. Even a high school student can carry out this simple experiment if he chooses the right one.

Aluminum is a rather difficult metal to solder, since the oxide film prevents solder from sticking to it.You can get rid of it in different ways, often time-consuming. Few people know that aluminum can be tinned by copper plating.

Many people know that a photoresistor is a simple electrical element for creating a light sensor. Together with the Winston Bridge, it is often used as a machine to turn off artificial lighting. You can also use it

This simple method of chemically purifying copper from oxide and darkening is available to absolutely everyone. All the ingredients for it can be easily found in the kitchen at home. Using this method you can clean copper coins, wires, tubes and any other

A shiny layer of chrome on metal children and tools makes them beautiful and also reliably protects them from corrosion. Its application is possible not only in production, but also at home using available equipment. Coating,

Nickel, having high corrosion resistance, perfectly protects other metals from corrosion and gives them an attractive appearance. Assembling a galvanic installation for nickel plating in a home workshop is not at all difficult and does not require

You can restore a nickel-plated surface or plate a new part with nickel at home. Moreover, this does not require expensive materials and deep theoretical knowledge. You just have to be careful with chemicals

If you have children and you want to please them with a common fun pastime, then make a lava lamp together. This is a project that is guaranteed to succeed, and at the same time you will definitely like it. Almost everything for its implementation can be found

Usually, in a home workshop, tabletop machines are not of their first youth. Often they have missing or damaged nameplates with factory data or operating modes. It’s a small thing, but it spoils the appearance of the machine and makes its image unfinished. Fortunately,

Silver is my favorite noble metal. I cast my first ring from 925 sterling silver when I first started trying to make jewelry at home. Now I want to blacken it. To do this, we will make a patina - a sulfur liver.

The most durable zinc coating on steel can be applied by electroplating at home. If the part is small, then it is not even necessary to have a powerful power supply, just batteries are enough. Consider the process of galvanizing steel from A

Copper, nickel, brass and aluminum are resistant to corrosion, so a thin layer of them on the surface of the steel can protect it from rust. One metal can be deposited onto another using electrolysis. But it doesn't always work. Let's check

Liquid plastic is similar to thick paint, except that after hardening it turns into plastic. Making it at home or in the garage is not difficult. All you need is a couple of ingredients.

To reliably protect a steel product from corrosion, it can be coated with zinc. Its layer is much more durable than paint, and it is also abrasion resistant. Zinc coating can be applied at home using a very simple technology.

When working with metal, you need to carefully remove rust, which will facilitate welding, engraving, painting, etc. On flat surfaces this is usually done with a grinder with a flap disc, a grinder, or a belt grinder. But if the part is embossed,

To refine steel and protect it from corrosion, coating is performed in various ways. This can be the creation of an oxide film, sputtering, etc. Most of these methods are too technologically advanced to be repeated at home.

If you connect a DC electric motor to a step-down transformer that converts 220V from an outlet into 12V AC voltage, then the rotor does not rotate normally. It just vibrates but doesn't turn. To

Nickel coating protects metal surfaces from corrosion and gives them a characteristic shine. It is abrasion resistant and durable. The nickel plating process can be recreated at home to cover various

Cleaning rusty parts from corrosion is a long routine job. In order not to bother with this, various liquids are often used that allow this to be done with minimal effort. Let's compare them in terms of cleaning efficiency of equally rusty springs, and choose

Anodizing helps strengthen the aluminum surface and make its color permanent. It consists in creating a special oxide film that can hold an organic or mineral dye in the pores. It provides protection from

To keep your hands warm in winter, you can use a sodium acetate-based pocket heater. This is a very simple, reusable device that can be easily made at home.

Zinc coating is the best solution for protecting steel parts and tools from corrosion, especially if they are subject to friction. You can apply it yourself very cheaply and without difficulty.
