What is glass?

Question:

What is glass?

Best Answer - Chosen by Asker:

Glass is a manufactured material formed when a mixture of sand, soda, and lime is heated to a high temperature and assumes a molten, or liquid, state. Unlike most other materials we produce, it does not form crystals as it cools. Instead, it becomes a "super-cooled liquid," behaving not unlike toffee and resisting any change in the arrangement of its molecules. This means that glass can be manipulated while hot to form any shape desired and will retain that shape as it cools. The hard, solid glass objects we are familiar with have all passed from a hot liquid state to a cold rigid one without changing structurally.
