Glass in Connecticut could be acquired from various nationwide and local stores. Glass is a solid substance, which exhibits state transition from molten and elastic rubber-like state to brittle and hard form. In most circumstances it is brittle and could be optically transparent. There exist two primary definitions of glass, that us, the restricted and the scientific definition.
The restricted definition restricts the composition of these material to be seventy five percent silica and sodium oxide and lime in varied composition. There are also minor additives in the composition, whose percentage concentration may not be easy to determine because it is very low. The scientific definition includes every solid that possesses a non-crystalline structure and which exhibits glass transition upon heating.
Quartz is the main raw material employed in the manufacture of this material. The production process entails addition of magnesium oxide, aluminium oxide, and calcium oxide to reduce the transition temperature of quartz. These oxides are preferred more than the carbonate of sodium, which is a good additive, but it dissolves in liquids like water making it unsuitable. The resulting glasses produced using this process contain around 10 percent of silica and hence are known as soda lime. Soda lime products are responsible for approximately 90 percent of the total output.
The properties of soda lime glasses are usually altered by adding other ingredients. Lead or flint glasses are more brilliant because barium is added into their composition. Barium increases refractive index which causes more specular reflection and optical dispersion. Lanthanum oxide provides high refractive index and low dispersion hence is used in making sunglasses. Lanthanum is a replacement of Thorium oxide which was dropped due to its radioactive nature.
Iron may be incorporated in glasses for absorbing infrared energy. A good example can be seen in filters used in movie projectors. Cerium (IV) oxide can be used in products that are meant for absorbing UV wavelengths. Other attributes of glass materials that may be altered include chemical, heat, and temperature resistance, clarity, and strength.
The production procedure entails movement of raw material from the excavation sites into heating furnaces. The materials are heated within the gas fired kilns until they melt. The end product is produced after refining and homogenization. Special purpose glasses are manufactured in small scale units such as electric melters, pot furnaces, and day tanks. Polishing of the end product is done by exposing it to extremely high pressure nitrogen.
Blowing and pressing methods are used in forming bottles and jars. After the required form is achieved, the material is annealed to remove stress. Surface lamination, coating, and treatment may be done to improve chemical durability. Chemical durability is also achieved through container internal treatment and container coating. Strength is achieved for use as toughened glasses, windshields, and bulletproof. Optical properties are affected through insulated glazing and anti-reflective coating among others.
Glass in Connecticut is made on large scale by numerous companies in the area. Clients may make orders for customized commodities for specific use. Most distributors and producers also host company blogs and/or websites from which one could get contact details for placing an order.
