'I have tried to formulate a criterion by which good pots may be judged . a pot in order to be good should be a genuine expression of life. It implies sincerity on the part of the potter and truth in the conception and execution of the work.' Bernard Leach (1887-1979) is generally reckoned to be the 'father of British studio pottery'. Born in Hong Kong, profoundly influenced by both an upbringing and studies in Japan, Leach developed a vision of pottery that interwove art, craft, design and philosophy. In 1920 he co-founded the Leach Pottery in St Ives, Cornwall, and A Potter's Book was first published in 1940. Within these pages Leach communicates his deeply-held convictions, through an account of the standards and materials essential to English slipware, stoneware, Japanese raku and Oriental porcelain.
