Type 1 glass, also known as annealed glass, is a regular window glass that is made from a combination of sand, soda ash, and limestone. This glass is usually found in windows, mirrors, and home decor.
Type 1 glass is heated to a high temperature to form its basic shape and then cooled gradually over time to create extreme strength and durability.
Type 2 glass, also known as tempered glass, is a stronger form of glass that is treated with extreme heat then quickly cooled. This process creates a strong, durable glass that is four times stronger than regular Type 1 glass.
Tempered glass is commonly used in car windshields, shower doors, and storefronts due to its superior strength and shatter-resistant properties.
Is soda lime glass tempered?
Yes, soda lime glass is typically tempered. Tempered glass is recognized as a safety glazing material because it is up to four times stronger than regular glass. This strength is derived from a thermal tempering process that activates forces within the glass.
The surface of tempered glass can also withstand extreme thermal variations ranging from -90°F to +400°F. In addition to its improved strength, tempered glass shatters into small rounded pieces, reducing the risk of injury.
Tempered glass is most commonly used for automotive components, shower doors, partitions, and office furniture. It can also be used for more creative applications like glass flooring, sculptures, and greenhouses.
What type of glass is used in laboratory and why?
Laboratory glassware is typically composed of either borosilicate glass or soda-lime glass. Borosilicate glass is composed of various elements including boron and silica, which creates a durable and chemically resistant material.
Borosilicate glass is the most common type of glass used in laboratories, as it is more resilient to temperature fluctuations and can tolerate higher temperatures, making it suitable for use in distillation and other processes that require heat.
Soda-lime glass is the other type of glass used fairly often in the laboratory, and is composed of calcium oxide, sodium oxide, and silica. This type of glass is usually cheaper and easier to form into various shapes, but is less chemically resistant and not suitable for use with higher temperatures.
Soda-lime glass is typically used for containers, as its manufacturing process allows for there to be fewer impurities compared to borosilicate glass, since the glass must be melted down and formed.
