Ceramic tableware made from fired clay is commonly categorized as porcelain, stoneware, or earthenware, depending on the clay composition and firing temperature.
With the exception of porcelain, most ceramics have microscopic pores on their surface and are naturally water-absorbent. Because of this, proper care is essential to preserve their beauty, prevent stains or odors, and allow them to age gracefully.
Before First Use
Stoneware and earthenware can benefit from a traditional process called medome (seasoning). While not strictly required, medome helps:
- Reduce staining and odor absorption
- Protect the surface during early use
- Encourage beautiful aging over time
Many well-loved pieces used in restaurants develop a rich, characterful patina that only comes with years of careful use. Medome helps guide this process naturally.
What Is “Medome” (Seasoning)?
Medome is a traditional Japanese method that uses starch to lightly seal the pores of clay tableware. This reduces sudden absorption of liquids, making the surface more resistant to stains while preserving its natural texture.
Medome is a one-time preparation and does not need to be repeated.
How to Perform Medome
Step 1: Heat with Starch
- Place the clay tableware in a pot large enough to hold it comfortably
- Add enough water to fully cover the pieces
- Add 1 tablespoon of flour or potato starch
- Heat gently over low heat for 15–20 minutes
Step 2: Cool Naturally
- Turn off the heat
- Leave the tableware in the water until it cools completely
- Doing this overnight is recommended
Step 3: Wash and Dry
- Remove the tableware and rinse off any residue
- Wipe with a cloth and allow to dry thoroughly
Your tableware is now ready to use.
Important Notes During Seasoning
- Always use low to medium heat to avoid cracking
- If water begins to boil strongly, reduce heat to prevent pieces from knocking together
-
When seasoning multiple items at once, place kitchen paper between them to prevent chipping
Stoneware and earthenware may require a little extra care, but in return they offer something special: a relationship that deepens over time. With gentle handling and simple attention, your tableware will age beautifully, enhance everyday meals, and become a cherished part of your daily life.
Enjoy using your favorite pieces for many years to come.
