OSC-2 and OSC-4 opaque fused quartz are manufactured by flame fusion of refined natural quartz crystal.
Opacity is obtained by generating a well-controlled distribution of microbubbles (typically 20 ~ 100 microns) through the use of a patented production process, which maintains the ultimate purity of the quartz.
Ingots can be cut, cored and surface ground to make plates, disks, rings, flanges and other shapes.
