Glass was founded by accident and its’ awesome tale dates to the second century. The oldest blueprint of glassmaking was discovered in the great library of Nineveh, Iraq (Library of the Assyrian King, Ashurbanipal). Glass is formed from a mixture of silicon atoms and alkaline atoms such as sodium or potassium. There are many types of glass, but the most common type is soda lime silica (SLS) glass, which is made by heating a mixture of sand, soda ash, and limestone. Another popular type of glass is borosilicate glass (BSG), which has extra resistance to temperature changes and is often used for special applications such as laboratory equipment or resistant glazing.
