No, in most cases, these are natural marks created by handwork and are not defects. 

During the pottery-making process, subtle traces may appear at various stages, including forming, glazing, and firing. 

However, if there are any noticeable chips, cracks, or peeling of the glaze, the item may be defective. In that case, please contact our concierge team and attach photos. 

No, this is not a defect.

Most of the tableware offered by MUSUBI KILN is handcrafted one by one by skilled artisans.

During the glazing and high-temperature firing process, small bubbles, pinholes, or slight rough textures may naturally occur as a result of air or minerals reacting within the glaze.

These features are a part of the unique character of handmade pottery, and even when pieces are made with the same clay, glaze, and kiln, slight differences in firing temperature, placement, or humidity can create individual variations in each item.

Please rest assured that these natural textures do not affect the product’s quality, functionality, or safety.

We hope you will appreciate these subtle differences as a reflection of the warmth and individuality that only handcrafted work can offer.

Small bumps are considered acceptable, but if you find any large ones, please contact our concierge team.

Detailed information about each product can be found under the “MAKER/BRAND” and “CRAFTS” sections below the product description on each product page.

Some of our products, like most glazed ceramics, may contain trace amounts of lead or cadmium. However, these elements are sealed beneath the glaze and are present at levels that do not pose a health risk when used as intended.

All MUSUBI KILN products have been tested in accordance with the Japanese Food Sanitation Act and meet its strict elution (leaching) safety standards.

Please note that testing standards and regulations vary by country. For this reason, we cannot guarantee that these test results will meet the specific regulatory requirements of every region.

If you have any further questions or concerns, please feel free to contact us.

Please rest assured that the fine lines shown in the image are not defects. These delicate patterns are known as “Kannyu” (crackle glaze), a natural characteristic of certain glazed ceramics.

Kannyu is different from cracks or damage caused by breakage. These lines do not penetrate the clay body, do not cause leakage, and do not affect the safe use of the item.

Even when ceramics are made with the same clay, glaze, and kiln, the appearance of Kannyu can vary depending on firing temperature and the position of the piece within the kiln. For this reason, some pieces may display Kannyu while others may not.

We hope you will enjoy these variations as part of the unique character and beauty of handmade pottery.

At MUSUBI KILN, we guarantee that all of our products are made in Japan.

Traditional Japanese crafts are highly valued worldwide, and counterfeit items are unfortunately common in the market. We take this issue very seriously and are fully committed to ensuring the authenticity and traceability of every product we offer.
