Precautions for using alumina crucibles:

When solids need to be heated with a high fire, use a alumina ceramic crucible. When using an alumina crucible, the crucible cover is usually placed obliquely on the crucible to prevent the heated object from jumping out and to allow air to flow in and out freely for possible oxidation reactions. Because the bottom of the crucible is very small, it usually needs to be placed on a clay tripod to be directly heated by fire. The crucible can be placed upright or obliquely on the iron tripod, and can be arranged by yourself according to the needs of the experiment.

After the alumina crucible is heated, it should not be placed on a cold metal table immediately to prevent it from breaking due to rapid cooling. It should not be placed on a wooden table immediately to prevent scalding the table or causing a fire. The correct way is to leave it on the iron tripod to cool naturally, or place it on an asbestos net to cool slowly. Please use crucible tongs to take the crucible.
