In the processing of quartz glass products, fire polishingi often a crucial step. Whether it is cold processing, hot processing or finishing of quartz glass, fire polishing will be involved. Therefore, the technology of fire polishing has always been the technical focus of our company.

Due to the different uses of fused quartz glass products, the fire polishing methods used will also be different. The following describes the fire polishing in different scenarios.

3. Optical fire throwing. This polishing method requires that the polished quartz product itself has a fine surface.
4. Fire polishing itself is a way to reduce hydroxyl. Such treatment can only be carried out for smaller quartz pieces.
