Castle Harris pottery vase with applied dragon, glazed in green, blue and yellow, incised 'Castle Harris', 21 cm high, 21 cm wide. John Castle (Jack) Harris (1893-1967) was born in May 1893 at North Waratah, New South Wales. Nothing is known his education or formal training in the arts. In the 1920s he was known professionally as Castle Harris and made a living from the sale of his and embossed leather tablecloths, which often incorporated Australian floral motifs. In the early 1930s Harris had lessons in clay modelling from Una Deerbon (1882-1972); on a visit to Melbourne in 1935, he worked briefly and informally at the Deerbon Pottery school and was employed at the Premier Pottery at Preston. Harris had a studio in hunter Street, Sydney, in 1939 and 1940, and another at Toongabbie in the mid-1940s. He seems to have had no time for contemporary, earthy, handicraft ideals or for the 'Accepted notion that handcrafted objects should be useful'. Often large, heavily decorated and frequently sculptural, his ceramics featured Australian and grotesque animals, and showed a strong Oriental influence. 1946 Harris shifted to the blue mountains and established a studio at Wentworth Falls. He later moved to Lawson where he continued his work.
