Crucibles are generally used to hold or heat solid, liquid or gaseous substances during melting or thermochemical reactions at high temperatures, as well as for melting and casting metals, alloys or glass. Specific uses include:
1. Chemical experiments in the laboratory, such as heating reagents, solvents, alloys, etc.
2. Purification and separation of metals in alchemy,
3. Melting metals and alloys during metal casting and injection molding.
4. Melting raw materials in processes such as manufacturing ceramics and glass.
