Yuan dynasty underglaze blue wares

[peterp]

Some general information on Yuan BW wares:

After the Ming dynasty (the one following the Yuan), even the Qing government was unaware that blue and white wares from the Yuan dynasty existed. They were rediscovered only in the early 20th century. However, most of the large pieces are now in the Topkapi in Istanbul, and in Iran. These were the collections of ancient rulers who coveted BW wares more than the Mongol rulers of China. The latter preferred metal vessels over porcelain, and most big Yuan B/W wares were exported to the Middle East. Small jarlets were exported to SE Asia, to areas in what is now Indonesia. Few large Yuan dynasty B/W items remain in China itself. Chinese researchers studying these wares often have to go to Turkey to see them, because they have hardly any.

Most of the items pictured seem to be from excavations.
