Borax is a white powder. 
Borax is a white powder. 

People use borax in many ways. It helps clean clothes. It can also help make green fire!
Some people use it to stop pests. It can stop ants and rats.
It is used to make things like glass. It is also used for pottery.
Some people even use it to make glue. It can make a rubbery slime. 
Borax is a white, shiny solid. It is a mineral found in a few places. It often forms in dry lake beds. This happens when seasonal lakes dry up. 
People use borax for many jobs. It helps clean clothes and can make water soft. In science labs, it helps keep liquids steady. This is called a buffer. 
Borax can help work with metals. It acts as a flux, which is a substance that helps metal flow. This is useful when soldering jewelry. 
It can even stop pests. It is used to control ants and rats. Because it works slowly, ants carry it back to their nests. 
Borax is a white, crystalline solid that people use in many ways. It is a type of salt known as sodium borate. You might also hear it called tincal or tincar. This mineral is found in only a few places around the world. It forms in dry lake beds when seasonal lakes evaporate. 
There are many ways that borax works. When you mix it with water, it creates a basic solution. This happens because of a part of the mineral called a tetraborate anion. You can also change borax by heating it up. If you heat it, the water inside the mineral leaves. This can turn the solid into a powder or even a glasslike substance. 
People have been using borax for a very long time. It was first discovered in the dry lake beds of Tibet. In the 8th century AD, people traded tincal along the Silk Road. They moved it from Asia to the Arabian Peninsula. Later, in the late 19th century, a man named Francis Marion Smith helped make it famous. His company was the Pacific Coast Borax Company. 
This name came from how the borax was moved. Workers used teams of mules to haul the mineral out of deserts. These deserts were in California and Nevada. 
Borax helps with many different tasks you might know. It is used in laundry detergents to help clean clothes. It can also be a flux, which is a substance that helps metal flow. This is helpful when people solder jewelry made of gold or silver. 
Borax is a white, crystalline salt known chemically as sodium borate. It is most commonly found as a hydrated borate of sodium. This means the mineral contains water trapped within its crystal structure. Borax is an important substance because it has many industrial and household uses. It can act as a cleaning agent, a pesticide, or a component in making glass. Because it is found in specific locations in large amounts, it can be mined economically. 
The chemical structure of borax is quite complex. It contains a tetraborate anion, which is a group of atoms that gives the substance its properties. When borax dissolves in water, this anion creates a basic solution. In its crystal form, the structure includes two four-coordinate boron centers and two three-coordinate boron centers. 
Borax exists in several distinct chemical forms depending on how much water is present. The term "borax" usually refers to the decahydrate, which is actually an octahydrate. This form has the chemical formula Na2B4O7·10H2O. There is also a pentahydrate form, which is actually a trihydrate with the formula Na2B4O7·5H2O. If you heat these hydrates above 150°C, you can produce anhydrous borax. This anhydrous version can exist in one amorphous, or glassy, form. It can also exist in three different crystalline forms known as alpha, beta, and gamma. The alpha form is the most stable version of the substance.
Humans have interacted with borax for many centuries. The mineral was first discovered in the dry lake beds of Tibet. Historically, natural borax was called tincal or tincar. In the 8th century AD, traders moved tincal from Tibet, Persia, and other parts of Asia along the Silk Road. They carried it to the Arabian Peninsula. Much later, in the late 19th century, Francis Marion Smith helped popularize the mineral. His Pacific Coast Borax Company used the famous "20 Mule Team Borax" trademark. 

The mineral is found in specific geological environments called evaporite deposits. These deposits form when seasonal lakes evaporate repeatedly. Some of the most important commercial sites are in Boron, California, and Searles Lake, California. 
Borax serves many specialized roles in science and industry. In metallurgy, it is used as a flux. A flux is a substance that helps metal flow by lowering the melting point of impurities like iron oxide. This is helpful when soldering gold or silver jewelry. It is also used in the "borax method" for gold mining. This method helps eliminate the need for toxic mercury during gold extraction. In laboratories, scientists use borate ions to create buffers. These buffers help maintain a steady pH level during sensitive chemical tests. Borax is even used in nuclear reactors as a neutron absorber to control reactivity.
In your own home, you might encounter borax in several ways. It is a common ingredient in laundry detergents and cleaning products.
