1. Quartz glass and its products are precious and brittle materials, so you must handle it with care and care when using it;

2. Quartz glass has the highest temperature requirement (1200°C, short-term 1400°C), this temperature should not be exceeded during use, otherwise it will crystallize or soften and deform;

3. Quartz glass that needs high temperature use must be wiped clean before use. It can be soaked with cleaning fluid and 10% hydrofluoric acid, then cleaned with high-purity water and treated with alcohol. Wear fine-line gloves during operation, and direct hand contact with quartz glass is not allowed;

4. Quartz glass products are allowed to be used continuously under high temperature, which is good for prolonging their life and improving temperature resistance. Conversely, if quartz glass products are used intermittently at high temperatures, the number of uses is limited;

5. Although the quartz glass material has high thermal stability, it can withstand sudden changes in temperature. However, in actual use, due to the difference in residual stress and product shape, there is a certain difference in thermal stability, so attention should be paid when using it;

6. Quartz glass is an acidic material. When used at high temperature, strictly avoid the same alkaline substance (such as

Contact with water glass, asbestos, potassium and sodium compounds, etc.), otherwise it will significantly reduce its anti-crystallization performance.
