In the Yuan dynasty China was under Mongol rule. During that period the
production of porcelain and pottery continued and basically followed the
Song heritage. There were some developments and improvements in
manufacturing methods made, though, and the focus of production shifted
to blue and white porcelain.
Although it is supposed that tiles did exist at least since the Tang dynasty, reliable proof for their existence is currently only available for the Yuan dynasty. Decorated Yuan porcelain tiles (Yuan dynasty: 1206-1368) had various shapes and were embedded in the wood of furniture as decoration.
Shufu porcelain (Shufu ware)
Shufu wares are a type of porcelain specifically made at the Hutian kiln during the Yuan dynasty. This type of porcelain has an appearance similar to "qingbai" or white porcelain, but has an off-white color with a very opaque glaze. The glaze of Shufu porcelain is completely non-reflective.
Together with an impressed porcelain decoration that is protruding from the base material, these features allow for easy recognition of Shufu ware.
Shufu plate (Yuan)
The name itself comes for the characters for "Shufu",
which can be found on some of the porcelain ordered by the court.
Porcelain items carrying the Shufu characters are considered imperial porcelain. The majority of Shufu items are smaller items for daily use, like plates, bowls, etc. Vases, jars, etc. are less frequent.
During the Zhizheng reign (1341–1368), towards the end of the dynasty (1206-1368)
underglaze blue painted decorations were further developed at Jingdezhen. But, at the same time development of underglaze red
decorations met technical difficulties and only limited quantities of
these could be produced.
Note: polychrome decorations existed already earlier, but they mostly were not painted, pictorial decorations; they were just an application of different color glazes. Opinions of the actual beginnings of underglaze blue decorations differ as archaelogical and other proof is still insufficient.
Export of blue and white porcelain
Quantities of these wares were exported to more than a dozen places in SE Asia, South Asia, the Middle East and possibly East Africa.
The blue and white porcelain exported to SE Asia consisted mainly of smaller items, while those going to the Middle East were mainly large items.

Today, the blue and white porcelain of this era is highly priced.
While in the Song dynasty celadon wares were probably the most favored ceramics, which were also heavily exported to the Middle East, the Mongol rulers took a liking to the still uncommon blue and white ceramics. This can be considered as one of the causes for a major decline of celadon producing kilns, overall, during the Mongolian rule. Jingdezhen with its blue and white porcelain became more important.
Only the kilns producing Longquan celadons in the south were an exception. While production of other celadon kilns generally declined, the production of Longquan kilns grew, paradoxically, due to huge export orders.
Green and Red Decorations (on-glaze)
Worth mentioning is also that painted (pictorial) on-glaze decorations in the colors red and green also reached new levels during this period. They now already had the quality of the Zhaozhou wares (aka Swatow wares) that were exported to Japan throughout the later Ming dynasty, until the 17th century.
