Glass is defined as an amorphous solid. The process of glass formation (vitrification) involves cooling a molten material rapidly enough to prevent the atoms or molecules from arranging themselves into a regular, repeating crystalline structure. If crystallization occurs during cooling, the material becomes a crystalline solid, not glass.
