How to use alumina ceramic crucibles correctly

1.When there is a solid to be heated with high heat, use a crucible. When using alumina ceramic crucibles, the crucible cover is usually placed diagonally on the crucible to prevent heated objects from jumping out and allow air to freely enter and exit for possible oxidation reactions. The crucible, due to its small bottom, usually needs to be placed on a mud triangle to be heated directly by fire. The crucible can be placed directly or diagonally on an iron tripod, and can be placed on its own according to experimental needs.

2. After heating, do not immediately place the alumina ceramic crucible on a cold metal tabletop to prevent it from cracking due to rapid cooling. It should not be placed immediately on wooden tabletops to prevent scalding or fire. The correct approach is to leave it on an iron tripod for natural cooling, or place it on an asbestos mesh to allow it to cool slowly. Please use crucible pliers for the retrieval of the crucible.
