Ceramics are highly absorbent.

If you use new, dry pottery as is, food juices or soy sauce may seep into the vessel and cause it to become dirty.

When using for the first time, soak in water for about half a day to make sure the container is sufficiently moist.

Normally, just soaking it in water before use is sufficient.

Also, when using the dishwasher, the utensils will be completely dry, so please soak them in water again before using.

After use, rinse with water as soon as possible.

I think this is a way to keep your dishes clean and in good condition for a long time.

Kohiki is particularly susceptible to moisture seeping in and discoloring, but in the world of tea ceremony this is called "rain leakage" and is highly valued.

Enjoy watching the vessel change as you use it.
