What is glass Glass is a hard and fragile material, it starts off as a liquid then becomes a solid when cooled. Glass is a hard and fragile material, it starts off as a liquid then becomes a solid when cooled.

How is it made Most glass is a mixture of a large amount of silica that comes from fine white sand or pulverized sandstone then combined with smaller amounts of an alkali like soda (sodium bicarbonate), lime (from limestone), (also recycled glass) and finally its all melted together.

Process of glass Forming: the glass is formed in machines. (Molded, pressed, rolled) Forming: the glass is formed in machines. (Molded, pressed, rolled) Cooled: the end product is then cooled on a conveyor belt for several hours or longer.

Recycling Glass is 100% recyclable, the recycle centers take the glass to co. so they can melt the glass, then the glass starts the process all over again.
