Handling of pottery


Beginning of use

-Pottery (earthenware)
Because the clay is coarse and highly absorbent, if used as is, it may absorb moisture and oil from soy sauce and food, causing to blot. For this reason, it is best to avoid tomato sauce, oil, and spicy foods at the beginning of use.

Boiling the vessel in rice water before using it for the first time will fill the spaces between the particles of the base material and the glaze (cracks in the glaze, not scratches), making it difficult for water and oil from the food to penetrate, thereby preventing stains and odors.
(1)Place enough rice water to cover the entire bowl in a pot.
(2)Boil over low heat for 15 to 20 minutes.
(3)Cool the entire pot, rinse it well, and dry it thoroughly.
If this is difficult, soak the pot in plenty of water for half a day to a day and wipe off the water before use.

After many years of use, there will always be "blotches" on the surface. We hope you will consider this as "the scenery of ceramics" and enjoy the change. If you do not like it, or if you want to do something about the blotches, please contact us.

-Porcelain (stone)
Please wash with a soft sponge and mild detergent before use.

Since it is made from a raw material called ceramic stone, it absorbs little water and is easy to handle, but recently some glazes have become permeable.
It is recommended that you soak the pot in olive oil or salad oil and rinse it with a mild detergent before using it. As time goes by, the glaze will blend in and become more pleasant.


About “Kan-nyu" (Intrusive)

Due to the difference in expansion rates of the glaze and the base material, the glaze of ceramics has fine cracks in it, which is called “Kan-nyu".

Please enjoy this unique view of pottery.


Each time you use it

Before serving dishes, both ceramic and porcelain dishes should be dipped in warm water for hot dishes and in cold water for cold dishes.
This will prevent soy sauce and oil from seeping through, and will also ensure that hot dishes remain hot and cold dishes remain cold.​​​​​​​

​​​​​​​Gold and silver tints may react with sulfur contained in vinegar, eggs, or rock salt, and may tarnish, so please refrain from using them if there are decorations on the inside.
​​​​​​​ If discoloration occurs, commercially available silver polish, toothpaste, or baking soda paste will help.

Ceramic ware becomes more moist and smooth with each use, and you can enjoy the change in texture over time.



You can wash it with a soft sponge and mild detergent.
Do not store the product while it is still moist, as this may cause mildew and odor.

When storing in a cupboard for a long period of time, be sure to dry it thoroughly before storing it.
In particular, ceramic ware has moisture soaked into the inside, so after wiping it clean, place it on a cloth and let it dry naturally overnight, depending on the climate.。

―Pottery (earthenware)
Please do not use microwave ovens or ovens.
Pottery is less sensitive to shock than porcelain, and we do not recommend placing it in the dishwasher together with porcelain or stacked on top of each other, as the water pressure and vibration may damage the ceramic pieces.

―Porcelain (stone)
Can be used in microwave ovens and dishwashers.
However, do not use gold-, silver-, or copper-painted items, as the colors may fade. Do not use ovens as they are not heat resistant.

If it gets stained or smelly

Both pottery and porcelain may become stained with tea stains or other stains as they are used.

-Pottery (earthenware)
If you are concerned about the smell, soak it in baking soda water for half a day to a day and then let it dry.
―Porcelain (stone)
Porcelain can be cleaned by dipping it in dishwashing bleach and then rinsing it clean with hot water.
However, it is best to avoid using bleach on gold, silver, and colored painted ware, as the colors may fade.
