- Do not immerse hot vessels in water or place them on a cold countertop, as sudden temperature changes can cause damage. Also, please avoid putting the container out of the refrigerator into the microwave immediately.
- There are some small cracks (penetrations) on the surface over the years, but there is no problem in use. Stoneware products may have intrusions at the time of purchase.
- When using the microwave, wipe off the moisture on the outside.
