Instructions for use
1. Quartz glass products are valuable brittle materials, so they must be handled with care and care during processing, installation, and use.
2. Although quartz glass has extremely high thermal stability and compressive strength, large products that have undergone annealing processing have different stress distributions due to their different shapes. Therefore, the thermal stability and compressive strength are also different, and special attention should be paid when using them
