Use and maintenance of quartz crucible

> The main chemical component of the quartz crucible is silica, which does not interact with other acids except hydrofluoric acid, but easily interacts with caustic alkali and alkali metal carbonate.

> Quartz crucible has good thermal stability and can be heated directly on the flame.

> Quartz crucibles, like glassware, are easy to break, so be careful when using them.

> Quartz crucible can use potassium hydrogen sulfate (sodium), sodium thiosulfate (baked at 212 degrees Celsius) as a flux, and the melting temperature must not exceed 800 degrees Celsius.
