Raku is a traditional Japanese pottery technique that originated in the 16th century. It is known for its unique firing process, where pottery is removed from the kiln while still hot and placed in combustible materials, creating distinctive surface effects. This method often results in vibrant colors and textures, making each piece one-of-a-kind. The term "Raku" also refers to a specific style of tea ceremony ware, often used in the Chanoyu or Japanese tea ceremony. Raku pottery is typically characterized by its hand-built forms and simple, rustic aesthetic, reflecting the principles of Wabi-Sabi, which values imperfection and transience.
