The composition and properties of soda lime glass are discussed in the following paragraphs.

Glass is all around us.When molten materials are cooled fast enough to prevent crystallization, the term "glass" can be used.The typical substances used to make glass are silicates, borates and phosphates.
Glass is an inflexible material that is formed by heating a mixture of dry solid materials until it reaches a semi-solid state, then cooling the mixture quickly to prevent it from forming the crystalline structure that most solid material have.As the glass cools, the atoms become locked in a state similar to that of a liquid before they can form a solid.Glass is neither a liquid nor a solid, but it has the qualities of both.
There are many different types of glass, and their properties vary with their chemical compositions, but there are a few characteristics that most glass have in common.Glass is strong despite its reputation.There are processes to minimize flaws and strengthen the glass.It is very resistant to scratches and abrasions.Glass is resistant to most industrial and food acids.It is elastic and can bend back to its original shape under stress.The breaking point of glass varies by type.
Glass is thermal-shock resistant and can endure intense heat and cold.It absorbs heat better than metal and is heat-absorbent.Glass can reflect, bend, transmit, and absorb light and is valued for its optical properties.It stores electricity well and resists electrical current.
The article compares two types of glass.Some of the same properties can be found in the two popular kinds of glass.
The most common and least expensive type of glass is soda lime glass.It has about 70% silica, along with soda, lime, and small amounts of other compounds.The temperature at which the silica is melted is lowered by the soda and the lime.Most of the glass is soda-lime.It is very workable because it can be softened multiple times during the fabrication of a product.It is a softer glass, which is an asset because it makes fabrication via cutting easier, but this does mean it is less scratch- resistant than other types of glass.
It is possible to increase the strength of soda-lime glass by using a chemical method.It is commonly used in windows.It is also used for household glass containers.Pyrex, a popular dishware brand, is made in the United States using Tempered soda lime glass.
The glass is made of at least 5% Boric oxide.The material of choice for a wide range of applications is borosilicate glass.The higher temperatures needed for the production of regular glass also account for its higher heat resistance.It faces less material stress than regular glass due to its lower thermal expansion coefficients.borosilicate glass is more durable than traditional glass and can be broken in accidents.Pyrex dishes were once used in the US but were replaced by soda lime glass.It is still used to make Pyrex in Europe.In laboratories around the world, everything from test tubes, rods, and beakers to graduated cylinders and pipettes are produced from borosilicate.
Boric oxide is a substitution for soda and lime in the manufacturing process of borosilicate glass.Boric oxide helps bind the silicate and aluminum oxide and sodium oxide.It is more temperature and chemical resistant than soda lime glass because of the Boric oxide in borosilicate glass.The borosilicate glass is harder than the soda lime glass.It is more difficult to make.If a glass product won't be subjected to extreme temperatures or chemicals, soda lime glass is the cheaper and easier to work with option.If a glass product has to deal with chemicals or thermal shock, borosilicate glass is the better choice.
