Strawfiring

Strawfiring is a traditional method of firing pottery that dates back thousands of years, originating in regions such as China, Korea, and Japan. The technique involves using natural materials like straw, wood shavings, or other organic fuels to create a reducing atmosphere inside the kiln during the firing process. Unlike modern electric or gas kilns, strawfiring relies on open flames and natural airflow, producing distinctive, uneven results that are prized for their organic character.

The process begins by packing the kiln with pottery pieces, often arranged loosely to allow air circulation. Straw or other combustible materials are then placed around or between the wares. As the kiln is heated, the straw burns, releasing gases that reduce oxygen levels inside, creating a unique chemical reaction. This reduction phase can cause subtle color shifts, such as turning copper glazes green or iron-rich clays darker, while also contributing to the formation of small, irregular bubbles or "pinholes" in the glaze.

Strawfiring is known for its unpredictability, as factors like fuel type, kiln construction, and firing temperature influence the final appearance. The lack of precise temperature control means each firing yields distinct results, appealing to potters who value handcrafted, one-of-a-kind pieces. While the method is labor-intensive and requires skill to manage safely, it remains a cherished technique among traditional potters and those seeking an authentic, artisanal aesthetic.

Modern adaptations of strawfiring include the use of controlled fuels like sawdust or compressed paper, though purists prefer natural straw for its purity. The technique is often associated with specific pottery styles, such as Korean *buncheong* ware or Japanese *shigaraki* pottery, where its effects are integral to the cultural heritage of the pieces. Today, strawfiring continues to be practiced by both traditionalists and contemporary artists as a means of preserving heritage techniques while exploring creative possibilities.
