Steele Fused Quartz Grinding Spindles

Advances and Processes in Precision Glass Polishing Technique1

2.5 GE 124 & NSG OZ are Fused Quartz glasses. Fused quartz is used in applications where good ultraviolet light transmission, very good thermal stability and chemical inertness (resistance to stains) are required. Fused Quartz is harder and more difficult to polish than borosilicate, so the cost is higher. For applications where

Machining Quartz? - Practical Machinist

Possibly, for prototyping, you could use one of the various size and shape quartz lamp bulbs that are now quite inexpensive and common. They are made of fused quartz, not the crystal variety. Quartz crystal is hardness 7 (Mohs scale), but fused quartz is somewhat softer, 5.3-6.5. They both withstand very high temperature.

Optical Flats - Peter Wolters

Lapmaster optical flats are manufactured from high quality fused quartz.Fused quartz is used because it possesses an extremely low coefficient of thermal expansion and extremely high resistance to abrasion. Even with the hardness of fused quartz the optical flat must be handled and used very carefully to prevent damage and scratches.
