Western scholars of ancient Chinese ceramics have long thought blue and white porcelain manufactured before the Ming (1368-1644 A.D.), dates to the Yuan (1279-1368 A.D.). Even in China today these porcelains are still termed Yuan Blue and White. Based upon first-hand surveys of sites in Inner Mongolia, Adam T. Kessler’s Song Blue and White Porcelain on the Silk Road demonstrates that blue and white was made during the Song (960-1279 A.D.) ended up in the hands of the Xi Xia (1038-1226 A.D.) and the Jin (1115-1234 A.D.). Blue and white found today in hoards was buried prior to Mongol invasions of China in the 1200s. Sites from the Philippines to Egypt have yielded Song blue and white. Also reviewed is the cobalt-bearing ore used by Song China to create blue and white.
