Those Hatchers had their noses in all kinds of business..... Sheaf, Colin and Kilburn, Richard The Hatcher Porcelain Cargoes. The Complete Record. Phaidon Christie's, London, 1988. The two cargoes salvaged by Captain Hatcher from the South China Sea covered by this volume provided valuable information for the dating of Chinese export ceramics at the very end of the Ming dynasty and at the middle of the eighteenth century. These two cargoes are fully discussed and many varieties of porcelain are illustrated. http://www.chinese-porcelain-art.com/chinese-porcelain-japanese-porcelain.html
