Corning® Vycor® Quartz

Glass Type: Fused Quartz


Corning® Vycor® 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® Vycor® also has good transmission in the UV range. SGP can CNC mill, drill, cut, lap, and polish this material in many shapes, sizes, and surface finishes.
