Leach promoted pottery as a combination of Western and Eastern arts and philosophies. His work focused on traditional Korean, Japanese and Chinese pottery, in combination with traditional techniques from England and Germany, such as slipware and salt glaze ware. He saw pottery as a combination of art, philosophy, design and craft – even as a greater lifestyle. A Potter's Book (1940) defined Leach's craft philosophy and techniques; it went through many editions and was his breakthrough to recognition.
