Glass

Definition

An amorphous, inorganic, usually transparent or translucent substance, consisting of a mixture of silicates or sometimes borates or phosphates, formed by fusion of silica or of oxides of boron or phosphorous with a flux and a stabilizer into a mass that cools to a rigid condition without crystallization.

Purpose

Glass is used for its optical properties, strength, and versatility in a wide range of applications, from windows and containers to electronics and art.

Examples of Use

• Windows: Providing transparency and protection in buildings and vehicles.
• Containers: Used to make bottles, jars, and other packaging materials.
• Electronics: Used in screens for smartphones, computers, and televisions.

Related Terms

• Silicate: A compound containing silicon and oxygen, commonly found in glass.
• Amorphous: A non-crystalline, solid state of matter.
• Flux: A substance used in the manufacture of glass to lower the melting point.

Notes

Glass can be modified with various treatments and coatings to enhance its properties, such as adding tints, increasing strength, or improving thermal insulation.
