This large 12in (31cm) wide earthenware teapot, with white tin glaze and aquamarine painted abstract designs by Alan Caiger Smith (b.1930), is priced at £580 from Kate Thurlow of London.
Smith, who studied at the Camberwell School of Arts and Crafts and trained in pottery at the Central School of Art and Design, established the Aldermaston Pottery in 1955. The cooperative workshop in Berkshire, which housed about seven potters, was known for its tin-glaze pottery and lustre ware in the tradition of William de Morgan.
