The float glass production process can be divided into five universal steps: 1.Batching of raw materials: The main components, comprising silica sand, calcium oxide, soda magnesium are weighed and mixed into batches to which recycled glass (cullet) is added. The use of 'cullet' reduces the consumption of energy.

Generally, the final mixture would consist of about 60% sand and 40% additives. The mixture is placed into a heat-proof crucible, and into the furnace or kiln it goes until it becomes liquid glass. The time needed for this to happen depends on the temperature of the furnace, the amount of mix being melted, and the exact ratio of sand to additives.

Jan 10, 2020How does glass become sand? Finely-crushed glass is basically a pure form of sand. When you grind down crushed glass to a fine powder, the difference between glass and sand is negligible at best; natural sand is made of quartz crystals of silicon dioxide and glass is the non-crystalline, amorphous form of silicon dioxide.

The main raw material used to make glass is sand. To make clear glass, a special sand called silica sand is used. This fine white sand is needed because it is very pure and does not contain other unwanted chemicals. It is "washed" to remove as many impurities as possible, as impurities can adversely affect the clarity and color of the glass.

Manufactured sand (M-Sand) is used as a substitution to the river sand in construction. River sand is becoming a decaying resource in some parts of the year due to the lack of rains to collect the sand on the river beds.

When those molecules are heated to high enough temperatures, the sand melts and loses its crystalline structure, and as it cools it gains an entirely different structure.
