Understanding Fused Quartz and Fused Silica | Machined ...

Yet sand is now the basic material used to create fused quartz. This process begins by melting natural quartz crystals present in quartzite sand, and then cooling it to produce an amorphous substance, also known as quartz glass. This process is carried out in vacuum in order to prevent inclusion, ripple and bubble formation in the viscous melt. The temperature at which the melt is processed is ......
