Making of fused quartz and fused silica

Historically the first method of producing fused quartz was by small scale fusion of quartz crystals in a flame Heraeus chemist Richard Küch first began fusing quartz rock crystal in a hydrogen/oxygen H2/O2 flame more than 100 years ago Heraeus has been producing quartz glass on an industrial scale with this process ever since.
