Raku pottery is a type of Japanese pottery known for its distinctive, often crackled, surface and vibrant colors. It’s created using a low-firing process, followed by a unique post-firing reduction technique.
Key Characteristics / Core Concepts
- Low-firing temperature: Raku pottery is fired at relatively low temperatures compared to other pottery types.
- Rapid firing and cooling: The quick firing and cooling process contributes to the distinctive texture and crazing.
- Reduction firing: After firing, the piece is removed from the kiln while still hot and placed in a container of combustible materials, creating a smoky, reduction atmosphere that alters the glaze’s color.
- Imperfect aesthetics: Raku pottery often features unpredictable and unique surface effects, making each piece one-of-a-kind.
- Functional and decorative uses: Raku pieces can be both functional (like tea bowls) and purely decorative.
How It Works / Its Function
The process begins with shaping and glazing the clay. It’s then fired in a low-temperature kiln. Once fired, while still glowing hot, the piece is removed and placed into a container—often a metal can—containing combustible materials like sawdust, straw, or newspaper. The burning materials rapidly deplete the oxygen, creating a smoky reduction atmosphere. This process dramatically affects the glaze, creating unique colors, textures, and sometimes cracks, adding to the rustic beauty of the piece.
The quick cooling further contributes to the unpredictable nature of the final product. The result is a piece of pottery with a unique character and often vibrant, unexpected colorations.
