The white ceramics I create use a technique called Kohiki (粉引), which originated on the Korean Peninsula in the 15th century during the Joseon Dynasty. The process involves forming vessels from red clay, then applying a layer of white slip, giving the piece its soft white appearance.

During China’s Song and Yuan dynasties, pure white porcelain with flawless forms was a luxury reserved for the aristocracy. In contrast, Kohiki emerged as an alternative for the common people, offering a white finish using more accessible materials and methods. (This is one interpretation of its origin.)

Over time, as tastes and techniques evolved, Kohiki gradually declined in popularity in Korea. However, in Japan — where cultural exchange with Korea was active. Kohiki tea bowls were embraced by the samurai class and became highly valued in tea ceremony culture.

Kohiki’s unique texture resonates with the Japanese aesthetic of wabi-sabi — a worldview that finds beauty in imperfection and impermanence. This sensibility remains deeply rooted in everyday Japanese life. Because of its warm, organic feel, Kohiki pottery is often used to complement and enhance the presentation of food on the dining table.

1. Clay selection and preparation
A darker iron-rich clay body is chosen and carefully wedged to remove air bubbles and ensure even consistency.

2. Forming the piece
The clay is shaped on a potter’s wheel or by hand into bowls, plates, or vessels, focusing on soft, natural forms rather than rigid symmetry.

3. Initial drying (leather-hard stage)
The shaped piece is left to dry until it reaches a firm but workable stage, allowing for surface treatment.

4. Applying white slip (Kohiki layer)
A thin layer of white slip (liquid clay) is brushed, dipped, or poured over the surface. This creates the signature soft, milky-white appearance.

5. Partial absorption and texturing
As the slip partially absorbs into the base clay, subtle variations, brush marks, and tonal shifts naturally emerge—key to Kohiki’s character.

6. Refining the surface
The surface may be gently smoothed or left intentionally raw in places to preserve organic texture and depth.

7. First firing (bisque firing)
The piece is fired at a moderate temperature to harden the clay while preserving the delicate slip surface.

8. Glazing (optional or selective)
A clear or translucent glaze may be applied to enhance durability while maintaining the soft matte quality of Kohiki.

9. Final high-temperature firing
The ceramic is fired again at a higher temperature, permanently bonding the slip and clay layers and stabilizing the form.

10. Finishing and inspection
Each piece is inspected individually, with slight variations embraced as part of the handmade aesthetic that defines Sogo’s work.

Before Use

Before using your new ceramic piece for the first time, we recommend soaking it in clean water for at least two hours. This allows the clay to fully absorb moisture, helping to prevent odors and stains from setting in.

Daily Care Instructions

Avoid leaving food or beverages in the vessel for extended periods (especially overnight), as moisture may seep through and leave water marks on surfaces. After use, be sure to dry the piece thoroughly to prevent any residual dampness.

Microwave & Dishwasher Use

Kohiki ceramics are microwave & dishwasher safe. For longevity, we recommend hand wash and limit microwave use.

Avoid Sudden Temperature Changes

Do not expose your ceramics to extreme temperature shifts (e.g., from fridge to microwave), as this may cause cracking.

On the Nature of Ceramics

Handcrafted ceramics naturally change over time, developing a richer patina with use. This gentle transformation is part of their unique charm. We hope this piece becomes a beloved part of your everyday life.
