How is Fiber Glass Wool (CAS: 65997-17-3) typically synthesized?

Fiber Glass Wool (CAS: 65997-17-3) is synthesized through a process called vitreous fiber manufacturing. This involves melting a glass batch consisting mainly of silica sand, soda ash, and limestone in a furnace. The molten glass is then spun into fine fibers using a high-speed spinning process. The fibers are cooled rapidly to form a glassy structure that is amorphous. This process typically does not require specific catalysts, but it can be optimized for yield and fiber quality through temperature and speed control.
