Notes on the use of quartz glass

1. Quartz glass products are precious materials, so they must be handled with care and care when using them; 2. All kinds of quartz glass have a maximum operating temperature, which 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 in 10% hydrofluoric acid or lotion, and then cleaned with high-purity water or 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 the life of quartz glass 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 extremely high thermal stability, it can withstand drastic temperature changes. However, in actual use, due to the difference in residual strain 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, strictly avoid contact with alkaline substances when used at high temperature, otherwise its anti-crystallization performance will be greatly reduced.
