Handling & Precautions
- Preheat the crucible gradually; avoid placing a room-temperature crucible directly into a hot furnace.
- Allow the crucible to cool naturally—avoid quenching or sudden temperature changes.
- Use appropriate tongs or heat-resistant gloves when handling hot crucibles.
- Clean using non-abrasive materials to protect the internal surface.
- Do not expose to sudden mechanical shock or drop on hard surfaces.
- Store in a clean, dry area to prevent contamination.
