Fused quartz – Wikipedia
Product quality. Fused quartz is normally transparent. The material can, however, become translucent if small air bubbles are allowed to be trapped within. The water content (and therefore infrared transmission of fused quartz and fused silica) is determined by the manufacturing process.

Fused quartz – Alchetron, The Free Social Encyclopedia
Fused quartz or fused silica is glass consisting of silica in amorphous (non-crystalline) form. It differs from traditional glasses in containing no other ingredients, which are typically added to glass to lower the melt temperature. Fused silica, therefore, has high working and melting temperatures.
