1. Before the first use, cook porridge or thick rice porridge to plug the tiny cracks in the purple sand casserole to avoid water seepage.

2. Don't dry-burn the purple rice cooker, and don't rinse it with water when it is still very hot, so as to avoid breakage and damage.

3. Please dry the water outside the purple casserole before each use.

4. Avoid using purple casserole to cook too sticky food, so as not to stick to the bottom of the pot or the wall of the pot, which is difficult to clean.

5. When using the purple rice cooker, handle it with care to avoid bumping. Hot purple casserole should not be placed directly on the ground. Two wooden chopsticks or other heat-resistant items can be put on it to keep the temperature balance inside and outside the pot wall and avoid the risk of cracking.
