Japanese raku is a traditional pottery technique that originated in Japan during the 16th century. It is characterized by its unique firing process, where pieces are removed from the kiln while still hot and then subjected to rapid cooling. This method creates distinctive surface textures and vibrant glazes, often with unpredictable results. Raku pottery is commonly used in tea ceremonies, reflecting its cultural significance. The process emphasizes spontaneity and creativity, making each piece one-of-a-kind. Artists often experiment with different materials and techniques, contributing to the evolving nature of this art form.
