Have you ever wondered how is glass made? The glass – float glass as we know - is manufactured by the PPG process. This process was invented by Sir Alistair Pilkington in 1952 and is the most popular and widely used process that describes how to make glass for architectural purposes in the world today.
It is also used to make roofing shingles, used on icy roads in the winter, for railroad ballast, and water filtration. Industrial sand and gravel is used to make glass, as foundry sand and as abrasive sand. For some applications, it is the silica content (quartz) of sand that makes it so valuable.
"Frac sand" is a high-purity quartz sand with very durable and very round grains. It is a crush-resistant material produced for use by the petroleum industry.
