Quartz crucible is a newly developed high-temperature resistant material. It has strong high temperature resistance and good stability to heat. It can be directly placed on a flame for heating. However, there are blue spots on the surface during use, and the quartz crucible needs to be sandblasted at this time.

1. A quartz crucible is a bowl-shaped container with a deep ceramic bottom. When solids are heated by fire, quartz ceramics are needed. Because it is more resistant to high temperatures than glassware, when in use, the cover is usually placed obliquely on the quartz ceramic to prevent heated objects from jumping out, allowing air to enter and exit, and oxidation reactions may occur.

2. Because the bottom of the appropriate crucible is very small, it is usually necessary to stand on the mud triangle to directly heat it with fire. It can be placed upright, tilted on an iron tripod, or placed by itself according to experimental needs. Do not place it on a cold metal table immediately after heating to avoid cracking due to rapid cooling. Quartz crucibles should not be placed immediately on wooden tables to avoid burning the table or causing a fire. The correct way is to place it on an iron tripod for natural cooling, or place it on an asbestos mesh for slow cooling.

After sandblasting, the quartz crucible changes to a certain extent in the degree of heating and oxidation. However, during the sand blasting process, attention should be paid to the correct steps and special care should be taken when using to avoid reducing the performance of the product.
