The ordinary glass is a mixture of sodium silicate, calcium silicate and Silicon dioxide, Na2SiO3.CaSiO3.4SiO2
There isn't just one ingredient used in glass, and there are different fusions of minerals to make it as well. Check out this paragraph, it tells of a few different types of glass that we use today.
From the wikipedia site:
Pure silica (SiO2) has a "glass melting point"- at a viscosity of 10 Pa·s (100 P)- of over 2300 °C (4200 °F). While pure silica can be made into glass for special applications (see fused quartz), other substances are added to common glass to simplify processing. One is sodium carbonate (Na2CO3), which lowers the melting point to about 1500 °C (2700 °F) in soda-lime glass; "soda" refers to the original source of sodium carbonate in the soda ash obtained from certain plants. However, the soda makes the glass water soluble, which is usually undesirable, so lime (calcium oxide (CaO), generally obtained from limestone), some magnesium oxide (MgO) and aluminum oxide are added to provide for a better chemical durability. The resulting glass contains about 70 to 74 percent silica by weight and is called a soda-lime glass. Soda-lime glasses account for about 90 percent of manufactured glass.
As well as soda and lime, most common glass has other ingredients added to change its properties. Lead glass, such as lead crystal or flint glass, is more 'brilliant' because the increased refractive index causes noticeably more "sparkles", while boron may be added to change the thermal and electrical properties, as in Pyrex. Adding barium also increases the refractive index. Thorium oxide gives glass a high refractive index and low dispersion, and was formerly used in producing high-quality lenses, but due to its radioactivity has been replaced by lanthanum oxide in modern eye glasses. Large amounts of iron are used in glass that absorbs infrared energy, such as heat absorbing filters for movie projectors, while cerium(IV) oxide can be used for glass that absorbs UV wavelengths (biologically damaging ionizing radiation).
Two other common glass ingredients are calumite (an iron industry by-product) and "cullet" (recycled glass). The recycled glass saves on raw materials and energy. However, impurities in the cullet can lead to product and equipment failure.
Finally, fining agents such as sodium sulfate, sodium chloride, or antimony oxide are added to reduce the bubble content in the glass. Glass batch calculation is the method by which the correct raw material mixture is determined to achieve the desired glass composition.
glass is made from sand which they heat to make it transparent....... also right now the glass from anything in melting but so slowly that it will take about over 1 million years for it shrink considerably. sorry but i don't why is is made out of that. probably because sand is a solid and you can melt it to make it transparent.
it is made out of melted sand which includes ionic compounds that form lattices, this is what makes glass strong.
Glass is made out of sand Glass is made of sand.
A Coke glass is made out of colored glass.
they are made of glass
Any glass article is made of glass
Who made the magnifying glass
You answered your own question. Balustrade glass is made of .... glass!
A window. Or what you may refer to is what is glass made of. Glass = Sand.
NO it is not made of glass in earlier times the sewing machine was made of metal. now it is made of plastic with glass in it
yes glass is made out of sand
they are made from glass
Glass is typically made by melting sand, Much of that sand consists of quartz. Some glass will also be made of recycled glass.
Sintered glass is made from glass powders pressed at a temperature under the melting point of glass.
A glass container is anything made of glass that is used to contain or store something. For instance, a jar or a bottle made of glass is a glass container.
It is made of glass, but the glass is curved so that light is magnified when it passes through it.
Glass is manely made of SAND!
No, glass is made from melted silicon dioxide.
Glass is made in most countries of the world.
They are melted down and made into more glass. Thanks
because it made it very beautful
The kind that's made of glass. The kind that's made of glass.
rock wool is made out of rock and glass wool is made out of glass
Glass is silica dioxide. It is made by melting silica sand.
Light bulbs are made out of glass.
Earth Made of Glass was created in 1999.
