Earthenware - Japanese Traditional Culture | Maintenance

Earthenware is a porous quality.
Moisture might infiltrate and discolor some earthenware with thin surface painting.
Some people are pleased with this process.
At the beginning to use, boil earthenware and rice of handful with a pan. When the hot water boils, weaken the fire, and boil during 20 to 30 minutes. Then shut off the heat, and wait until the hot water is cooled.
Wash it in water, and dry naturally.
If the glaze is thick, soak it to water 10 minutes or more.
And you had better wash it in water before using it usually.
