Properties of fused silica Heraeus Group
The purities of fused quartz and fused silica are outstandingly high. Synthetic fused silica from Heraeus contains total metallic contamination below 1ppm. For fused quartz the amount is approximately 20 ppm and consists primarily of Al2O3 with much smaller amounts of alkalis, Fe 2 O 3, TiO 2, MgO and ZrO 2.

How is a quartz crystal formed? Quora
In either case, the liquid can no longer hold as much silica in solution, so it begins to crystallize. Depending on how much of this silica rich water was formed, and how much room there is for the crystalization to grow, crystals of Quartz begin to form. You can get tiny Druzy Quartz crystals, or giant monsters weighing TONS.
