Glass is made from sand. The most popular sand used in glass production is white quartz sand. When heated up, the sand becomes bright and translucent. The sand is melted in an extremely hot oven, where it melts into glass. As the glass cools down, it becomes sticky and can be molded into different shapes.


Glass is made by melting sand.

Glass is heavy and it breaks easily when it falls. However, it resists scratches well. It is widely used to create drinking glasses, windows and fine objects. Plastics have reduced the amount of glass used in functional items.


Glass can be used to make drink glasses (on the left) and greenhouses (on the right).
