Glass in Design

Understanding Glass: Properties and Uses

Glass is a unique material with many different properties that make it useful in construction, packaging, technology, and design.
Think of it like a superhero material—strong in some ways but fragile in others, and with different “powers” depending on its composition.

Color and Composition

Glass can change color when metallic oxides (special chemicals) are added.
1. Different elements create different colors:
  1. Iron makes glass green.

Sulfur makes it yellow or brown.

Copper makes it blue.

Chromium gives a deep green shade.

Example: Stained glass windows in churches or colored glass bottles (like green wine bottles) are made using these additives.

Transparency

One of glass’s best features is that it lets light through, making it ideal for windows, skylights, and display cases.

It’s widely used in architecture to bring in natural light, reducing the need for artificial lighting.

Example: Transparent glass is used in storage containers so you can see what’s inside without opening them.

Strength and Brittleness

Glass has high compressive strength (it can handle a lot of weight pressing down on it), but low tensile strength (it breaks easily if pulled or bent).
It’s brittle, meaning it can shatter easily, but this can be reduced with special treatments:
1. Tempered glass is heated and cooled rapidly to make it stronger (used in car windows and shower doors).

Laminated glass has layers that hold it together when cracked (used in car windshields for safety).
