The use of quartz glass products should follow certain precautions since quartz glass are relatively expensive materials, attention should be paid to:

1. All kinds of quartz glass products have a maximum operating temperature, which should not be exceeded during use, otherwise it will crystallize or soften and deform.
2. Quartz glass is an acidic material. Strictly avoid contact with alkaline substances (such as water glass, asbestos, potassium-sodium compounds, etc.) when used at high temperature, otherwise its anti-crystallization performance will be greatly reduced.
3. Quartz glass products are allowed to be used continuously at high temperature, which is good for prolonging the life of quartz glass and improving the temperature resistance. On the contrary, the intermittent use of quartz glass products at high temperature has a limited number of uses.
4. Although the quartz glass material has extremely high thermal stability, it can withstand severe temperature changes. However, in actual use, due to the difference in residual strain and product shape, the thermal stability has a certain difference, and attention should be paid when using it.
5. Quartz glass that needs to be used at high temperature must be wiped clean before use. It can be soaked with 10% hydrofluoric acid or lotion, then cleaned with high-purity water or treated with alcohol. Thin-line gloves should be worn during operation, and it is not allowed to directly touch the quartz glass with hands.

6. Any solution containing substances that corrode glass should not be stored in quartz glass instruments for a long time. And glassware cannot be heated on a flame or electric stove or baked in a drying oven.
