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. Although the terms quartz and fused silica are used interchangeably, the fundamental structures and creation of each glass differ.

Today, Fused Quartz is defined as a material made by melting high purity, naturally occurring quartz crystal. The melting is conducted at around 2000°C, using either an electrically heated furnace (electrically fused) or a gas/oxygen fueled furnace (flame fused).
Quartz is extremely pure and therefore has high working and melting temperatures. Its optical and thermal properties make it superior to those of other glass materials due to its purity. Quartz and fused silica are ideal for semiconductor fabrication and laboratory equipment.
