The making of glass fiber | CompositesWorld

The glass fiber process. Textile-grade glass fibers are made from silica (SiO 2) sand, which melts at 1720°C/3128°F.SiO 2 is also the basic element in quartz, a naturally occurring rock. Quartz, however, is crystalline (rigid, highly ordered atomic structure) and is 99% or more SiO 2.If SiO 2 is heated above 1200°C/2192°F then cooled ambiently, it crystallizes and becomes quartz.

The glass particles have a slightly negative charge which attracts smaller particles allowing it to filter between 5 and 10 microns. The other thing that separates this media from the other two is that sand and Zeolite only use the top 6" of the media bed to filter out debris. Glass media uses all of the filtering media down to the pea gravel.
