Making of fused silica - Heraeus
Plasma outside deposition (POD) For this process a plasma heat source is used to "burn" chemical precursors and deposit a thin glass layer on a rotating target. The target can be a tube or a solid rod, it is not necessarily round. Because of the high temperature of the plasma, this process is best suited to produce fluorine doped fused silica.

What It Takes to Make Food-Safe Glass Bottles - O.Berk
To begin the glass bottle making process, the silica sand must be mixed with several other materials. Soda ash (sodium carbonate) is added in a smaller percentage to decrease the melting point of the sand. This allows the sand to melt faster in the furnace, saving energy along the way. Adding only soda ash to the sand would eventually result in ...

How Do You Remove Silica from Industrial Water and Wastewater?
Granular silica removal. Silica can exist in water as relatively large particles, known as silica granules or granular silicates. Granular silica removal is generally accomplished through physical chemical separation. The most common approach is lime softening, which is a process where calcium hydroxide (lime) is added to water to remove hardness.
