Borax Decahydrate is the refined form of natural sodium borate. 
Composed of boric oxide (B2O3), sodium oxide, and water, Borax Decahydrate is a mild, alkaline salt, white and crystalline, with excellent buffering and fluxing properties. 
Borax Decahydrate is an important multifunctional source of B2O3 (e.g. frits), particularly for processes in which the simultaneous presence of sodium is beneficial.
Borax is available in large crystal, powder, and granular form, the latter being the most practical for ceramic use. 
Although the 10 molecules of water in the theoretical formula vary somewhat, they are the source of the designation "10 Mol Borax". 
The water content can vary with storage (Borax Decahydrate tends to loose water with time). 

Where precision is required, Borax Decahydrate is necessary to measure the water content just before use.
Borax Decahydrate begins to melt in Borax Decahydrates own water of crystallization at 60.8C. 
Borax Decahydrate is soluble in water, acids, glycol and other solvents. 
Almost all American borax comes from deposits of the crystalline precipitate mineral tincal in the Mohave Desert of California (Asian borax is called Tincal).
The solubility of borax normally disqualifies Borax Decahydrate for use in clay bodies and glazes (since during drying Borax Decahydrate will come to the surface with the water and be concentrated there).

Actually, this phenomena can be used to advantage to make self glazing products like Egyptian Paste and Borax Decahydrate can produce a hardened surface in non-fired products. 
In addition, the migration issue during drying can be tolerated in some circumstances, borax can be employed in a traditional ceramic slip or glaze blend as a low-cost super-flux to produce a glaze or slip for low temperatures.
Borax has many technical, granular and powder grades of this material. 
"20 Mule Team" borax is this material. 
Borax Decahydrate is also produced at the Bandirma Borax Plant in Turkey.

Chemical and physical properties
Stability
Borax decahydrate is chemically stable under normal storage conditions.
Borax decahydrate has a slight water vapor pressure which increases with warmer temperatures. 
This can cause crystallization at particle contact points, resulting in caking. Borax decahydrate will slowly lose water of crystallization if exposed to a warm, dry atmosphere. 
Conversely exposure to a humid atmosphere causes caking. 
When storing the product, care should therefore be taken to avoid wide fluctuations in temperature and humidity, and to ensure that the packaging is not damaged.

Buffering action
Dissolved in water, borax decahydrate hydrolyzes to give a mildly alkaline solution. 
Borax Decahydrate is thus capable of neutralizing acids. 
Borax Decahydrate also combines with strong alkalis to form compounds of lower pH. 
The relatively constant pH of borax decahydrate solutions makes Borax Decahydrate an excellent buffering agent.

A salt of boric acid, Borax Decahydrates typical form is a white powder consisting of soft water-soluble crystals.  
Borax Decahydrates anti-fungal properties make Borax Decahydrate useful in treating certain skin conditions, and Borax Decahydrate is also used in pest control applications.  
Borax has several industrial applications as well, including use as a flux to eliminate undesired metal oxides and use in flame retardants. 
Originally discovered in Tibet, Borax occurs naturally in the deposits of dry lake beds, where repeated seasonal evaporation produces a bed of clay and natural salts.  

Today the southwest United States produces most of the world’s mined Borax, with California and Nevada having the largest natural deposits.  
Other sources include Turkey, Italy, and the Atacama Desert of Chile.  
While Borax is generally obtained via mining, Borax Decahydrate can be produced synthetically from other boron containing compounds. 
In addition to Borax Decahydrates use in detergents, Borax is used as an emulsifier and natural preservative and has cosmetic and pharmaceutical applications in creams, ointments, and lotions.  
Borax Decahydrates alkalinity allows Borax Decahydrate to be used as a pH buffering agent to neutralize acids.  
In engine coolants and antifreeze, Borax is sometimes used as a corrosion inhibitor as Borax Decahydrate can prevent oxidation of ferrous metals.  

In starch adhesives for corrugated paper, Borax additives serve to improve viscosity, wet tack, and water holding properties.  
Borax Decahydrate also plays an important role in the production of ceramics and glass for lenses, car headlights, and other specialized examples where optical and physical properties must be precisely tailored.  
While used as a food additive in some countries, Borax is not permitted to be used in food products in the United States.

Borax Decahydrate is used to make buffer solutions in biochemistry, as a fire retardant, as an anti-fungal compound, in the manufacture of fiberglass, as a flux in metallurgy, neutron-capture shields for radioactive sources, a texturing agent in cooking, as a cross-linking agent in Slime, as an alkali in photographic developers, as a precursor for other boron compounds, and along with its inverse, boric acid, is useful as an insecticide.
In artisanal gold mining, borax is sometimes used as part of a process (as a flux) meant to eliminate the need for toxic mercury in the gold extraction process, although it cannot directly replace mercury. 
Borax was reportedly used by gold miners in parts of the Philippines in the 1900s.
Borax was first discovered in dry lake beds in Tibet and was imported via the Silk Road to the Arabian Peninsula in the 8th century AD.
Borax first came into common use in the late 19th century when Francis Marion Smith's Pacific Coast Borax Company began to market and popularize a large variety of applications under the 20 Mule Team Borax trademark, named for the method by which borax was originally hauled out of the California and Nevada deserts

What is borax
Borax Decahydrate is one of the most important boron compounds, with the chemical formula Na2[B4O5(OH)4]·8H2O. 
However, the common usage of the term “borax” may refer to various very similar compounds, distinguished by their water content, such as:

Anhydrous borax or sodium tetraborate (Na2B4O7)
Borax pentahydrate (Na2B4O7·5H2O)
Borax decahydrate (Na2B4O7·10H2O)
Borax is used in all sorts of cleaning recipes, where it’s added for the compound’s stain-fighting and grease-cutting abilities. 
You’ll find borax present in various products and industries, not only cleaning supplies. 
In some gold mining operations, Borax Decahydrate replaces mercury, for instance. 
Borax is also used in food as a preservative, although Borax Decahydrate is banned for this purpose in the United States.

What Is Borax?
Borax is a powdery white substance, also known as sodium borate, sodium tetraborate, or disodium tetraborate. 
Borax Decahydrate’s widely used as a household cleaner and a booster for laundry detergent. 
Borax Decahydrate’s a combination of boron, sodium, and oxygen. 
Borax is often found in dry lake beds in places like California’s Death Valley, where the water evaporated and left behind deposits of minerals.
Boric acid is made from the same chemical compound as borax and even looks like Borax Decahydrate. 
But while borax is commonly used in cleaning, boric acid is mainly used as a pesticide. 
Boric acid kills insects by targeting their stomachs and nervous systems. 
Both borax and boric acid in loose powder form can be harmful if swallowed, particularly for children. 
Borax Decahydrate can also irritate your skin.

Household Uses of Borax
-The best-known use for borax is as a cleaner, but you can find the ingredient in many other household products, including:
-Specialty toothpastes and mouthwashes
-Cosmetics such as lotions, skin creams, moisturizers, sunscreen, and acne care products
-Paint and ceramic glaze
-Herbicides
Borax is also an ingredient for making putty-like “slime” for kids. 

Medical Research
Scientists have been studying whether the compounds in borax might help your body fight conditions like arthritis or osteoporosis, but more research is needed to know if or how they might work.

Chemical Class and Type:
Boric acid and its sodium borate salts are active ingredients in pesticide products used as insecticides, acaricides, algaecides, herbicides, fungicides and as wood preservatives.
Boric acid and borate salts exist naturally in rocks, soil, plants and water as forms of the naturally occurring element boron.
Boric acid and borate salt pesticides were registered for use in 1948 and were reregistered by the United States Environmental Protection Agency (U.S. EPA) in 1993.
The borate salts include sodium tetraborate, disodium octaborate and sodium metaborate.
Both sodium tetraborate and disodium octaborate occur in several hydration states.
Sodium tetraborate decahydrate is also known as borax.

Uses:
Uses for individual boric acid and borate salt products vary widely. 
Boric acid and its sodium borate salts are active ingredients in pesticides used against insects, spiders, mites, algae, molds, fungi, and weeds.
Boric acid and borate salt products are used on a variety of sites including sewage systems, food and non-food crops, outdoor residential areas, and indoor sites such as homes, hospitals, and commercial buildings.
Commercial formulations of boric acid and borate salts include liquids (solutions, emulsifiable concentrates), granules, wettable powders, dusts, pellets, tablets, rods and baits in concentrations ranging from 1% to nearly 100%.

Signal words for products containing boric acid may range from Caution to Danger.
The signal word reflects the combined toxicity of the active ingredient and other ingredients in the product. 
See the pesticide label on the product and refer to the NPIC fact sheets on Signal Words and Inert or "Other" Ingredients.
In addition to pesticidal uses, boric acid and borate salts may be used as soil amendments in boron-deficient soils.
Boric acid, anhydrous sodium tetraborate and sodium tetraborate decahydrate (borax) are also used as components of plant fertilizers, household cleaners, laundry detergents and personal care products.

Boron is present in many foods and drinking water supplies. 
Estimated human consumption of boron in the U.S. diet ranges from 0.02 mg boron/day to more than 9 mg boron/day with an estimated average intake of 1.17 mg boron/day for men and 0.96 mg boron/day for women.
Recent evidence has suggested that boron may be an essential micronutrient.
Boric acid and borates are released into the environment by human activities including the use of borate salt laundry products, coal burning, power generation, chemical manufacturing, copper smelters, rockets, mining operations and industries using boron compounds in the manufacture of glass, fiberglass, porcelain enamel, ceramic glazes, metal alloys and fire retardants.

Physical / Chemical Properties:
The water solubility of boric acid and sodium tetraborate (all hydration states) increases at higher water temperatures.
Boric acid is a weak acid (pKa = 9.15), existing in aqueous solutions at or below pH 7 as undissociated boric acid. 
Above pH 10 the metaborate anion dominates the solution.3
Sodium metaborate is much higher in solubility and alkalinity than the other borates. 
Sodium metaborate solutions range in pH from 10.5 to 12, while borax solutions typically have a pH of about 9.24.
To convert doses of boron compounds to boron equivalents, multiply the dose by the compound's boron content.
For example, multiply the number of mg boric acid by 0.1748 to find the equivalent dose of boron in mg.


Borax
BORAX DECAHYDRATE (AKA sodium borate, sodium tetraborate or disodium tetraborate) is a refined form of natural sodium borate. 
Borax Decahydrate is used in many cleaning products as a pH buffering agent.
