Fused silica is made of very high purity crystal silica (quartz sand), melted by fusion in electrical arc ovens at temperatures of 1800-2000 ℃ and then cooled sufficiently fast to avoid crystallization and obtain transparent amorphous silica (silicon dioxide). Fused silica emerges from this proces...
