Characteristics of Ceramic Products
About Glaze
Even when made with the same ingredients, glazes can vary greatly depending on the firing conditions. In addition, because much of the process is done by hand, the application of glaze can differ from piece to piece. The following is an overview of the variations that may occur within the acceptable range. Please understand these as inherent characteristics of ceramics.
- Glaze Unevenness (Dripping, Pooling)）
Areas where the glaze is applied thickly may appear in a deeper shade, and streaks resembling runs of glaze can sometimes be observed.
- Pinholes
As air contained in the body forms bubbles and emerges on the glazed surface, tiny holes may appear. In addition, regions where the glaze accumulates are more prone to blistering, resulting in the formation of fine bubbles.
- Iron Powder (Spots)
Decorative enamels and colored glazes often contain iron, which during firing may adhere to the kiln and transfer onto other pieces. Furthermore, because the materials are natural, even white bodies or glazes may contain fine iron particles.
- Opacity (Milky, White Floating)
Some glazes develop white, cloudy crystals. In kiln-transformation glazes, there is a type known as “sea cucumber glaze,” and some colored glazes contain components that tend to become opaque (in colors such as red, Turkish blue, beige, etc.). Areas where the glaze piles up may develop a cloudy, white appearance.

- Kiln-Transformation Glaze
Due to various factors like the state of the kiln and the thickness of the glaze, each piece finishes uniquely. Please enjoy the unique aesthetics of kiln-transformation glazes, such as spots, unevenness, and variations in shading.
- About Recycled Tableware
Recycled tableware contains 20% once-fired pieces. As a result, compared to standard porcelain, achieving uniformity is more challenging, and differences in color and shape are likely to appear. Specifically, phenomena such as “pinholes,” “unevenness (shade variation),” “iron powder,” “variations in color and texture,” “distortion,” and “clay wrinkles” may occur. Please understand and accept these as the inherent qualities of recycled materials.
