Glass Type: Fused Quartz
Description
Corning(R) Vycor(R) is a material that is comparable to and sometimes used in place of either fused silica or fused quartz. It has good resistance to heat and thermal shock. Corning(R) Vycor(R) also has good transmission in the UV range. CGQPI can CNC mill, drill, cut, lap, and polish this material in many shapes, sizes, and surface finishes.
