The material of purple sand has poor thermal conductivity and the power of purple casserole is low.

1, the thermal conductivity of purple sand material is poor: the thermal conductivity of purple sand material is poor, the temperature rises slowly after heating, and it is difficult to reach boiling state.

2. The power of purple casserole is low: the power of purple casserole is lower than that of ordinary pot, so the heating time is long and it is not easy to boil.
