Raku firing, an age-old ceramic technique originating in Japan, has captivated artists and art enthusiasts for centuries. The process, known for its unpredictable results and stunning metallic finishes, involves removing pottery from a kiln while it’s still red-hot and placing it into combustible materials. This creates a reduction atmosphere, starving the clay of oxygen and resulting in unique and beautiful color variations.
A Brief History of Raku
The roots of raku pottery can be traced back to 16th-century Japan, where it was primarily used for crafting tea bowls. These bowls, typically small enough to fit in one’s hands, were prized for their simple elegance and the unique character imbued by the raku firing process.
In the mid-20th century, American ceramist Paul Soldner introduced raku to the Western world, forever changing the landscape of contemporary ceramics. Soldner experimented with post-firing reduction, a technique that involves placing the hot pottery into containers filled with combustible materials. This innovation opened up a world of possibilities, allowing artists to achieve an even wider range of colors and textures.
The Art of Raku: A Step-by-Step Guide
While the beauty of raku lies in its unpredictable nature, understanding the process can deepen your appreciation for this captivating art form.
1. Preparing the Clay
Like any pottery piece, the journey begins with shaping the clay. Whether you’re throwing on the wheel or hand-building, the form itself will ultimately influence the final outcome of the raku firing process.
2. Bisque Firing
Once the clay form dries, it undergoes its first firing in a kiln. This initial firing, known as bisque firing, hardens the clay and prepares it for glazing.
3. Glazing
After the bisque firing, the piece is ready for glazing. Raku glazes are specifically formulated to react to the rapid temperature changes and reduction atmosphere of the raku firing process, resulting in the characteristic metallic sheens and vibrant colors.
4. Raku Firing
The magic truly unfolds during the raku firing. The glazed pottery is placed in a kiln and brought to a high temperature. Once the glaze reaches its melting point, the piece is carefully removed from the kiln while still glowing red-hot.
5. Post-Firing Reduction
The red-hot pottery is then placed in a reduction chamber—a container filled with combustible materials like newspaper or sawdust. This creates an oxygen-deprived environment, causing the glazes to react and develop their unique colors and textures.
6. Cooling and Cleaning
After the reduction process is complete, the pottery is left to cool. Once cool, the pieces are cleaned to remove any residue from the firing process, revealing the final, breathtaking results.
My Experience with Raku Firing
I remember my first experience with raku firing vividly. The intense heat, the dramatic removal of glowing pottery from the kiln, and the anticipation as I placed my pieces into the reduction chamber—it was an exhilarating experience that left me hooked.
I use a metal chamber filled with newspaper for my post-firing reduction. By controlling the amount of air allowed into the chamber, I can influence the intensity of the reduction and the final outcome of my pieces. It’s like conducting a symphony of fire, with each element playing a crucial role in the final masterpiece.
The most exciting moment for me is opening the reduction chamber after the firing. It’s always a surprise—a moment of truth where I get to witness the alchemy of fire and glaze firsthand. Sometimes, I achieve the exact effects I envisioned, while other times, the results are entirely unexpected, pushing the boundaries of my creativity and reminding me of the inherent beauty of this unpredictable art form.
Embrace the Magic of Raku
Raku firing is an art form that embraces the unexpected. It’s a dance between control and surrender, where fire and glaze intertwine to create one-of-a-kind pieces that are as unique as the process itself.
If you’re drawn to the allure of raku, I encourage you to explore this fascinating world. Visit local pottery studios that offer raku firing workshops, experiment with different glazes and techniques, and don’t be afraid to embrace the unknown. You might be surprised by the magic you create.
