Making of fused quartz and fused silica
One that starts with high purity quartz, or other Silicon dioxide containing minerals that are fused using various heat sources. This Material class is termed fused quartz. The other is called fused silica and starts with gaseous silicon containing chemicals (e.g. SiCl4) that are burned in the presence of oxygen to form silicon dioxide.
