Materials Lecture 8 - Glass

These flashcards cover key concepts, properties, and types of glass discussed in the lecture on materials.

Amorphous Solid

Any noncrystalline solid in which the atoms and molecules are not organized in a definite lattice pattern.

Soda-lime Glass

A type of glass that makes up about 90% of manufactured glass, consisting of 60-75% silica, 12-18% soda ash, and 5-12% lime.

Pilkington Float Process

A method to produce flat glass by pouring molten glass onto molten tin to create a smooth surface.

Float Glass

A type of glass produced using the Pilkington Float Process, characterized by its smooth surface and uniform thickness.

Toughened Glass

Glass that has been reheated to 600-800°C and then cooled rapidly to increase its strength and reduce shattering.

Heat Strengthened Glass

Glass that is heated to 600-800°C and cooled more slowly than toughened glass, providing more strength than ordinary glass.

Laminated Glass

Glass made by bonding two or more layers of glass with an interlayer, enhancing safety and reducing shattering.

Low-E Glass

Glass with a low emissivity coating that reflects infrared radiation while allowing visible light to pass. it has a thin, delicate metallic coating making it delicate to clean

Thermal Gradient

A difference in temperature that can induce cracking in glass.

Cullet

Recycled glass used in the manufacturing process of new glass products.

Close Loop Recycling 

A sustainable process where cullet is collected and reused to create new glass products, minimizing waste and energy consumption.
