Swatow wares from Zhangzhou?

• Shantou (Swatow)
  
• Chaozhou
• Zhangzhou
• Yuegang

They ware called that way for centuries.

The coastal place called Swatow by the foreign traders in the past, is now called Shantou in Chinese. At the time when the 'Swatow' wares were exported it was actually only a small port, hardly able to serve as shipping port for the huge quantities.
For some unknown reason several hundred years ago Swatow's name became linked with the flourishing export commodity porcelain. But actually, neither was it produced in its vicinity, nor was it exported from here.

Inland from Shantou lies Chaozhou, which was also a ceramics production area. As both the Chaozhou and Zhangzhou areas belong to the same linguistic and cultural area, the Minnan region, would it be possible that Chaozhou did work with Zhangzhou to fill orders from abroad at the time?
Could it be that smaller quantities were shipped from here to the main production area Zhangzhou in order to help filling large orders from abroad?

However, archaeological excavations in the late 20th century in China provided proof that these wares were actually produced in Zhangzhou, they are now usually called 'Zhangzhou' wares except by a few who still have not discovered the discrepancy yet.

Zhangzhou is an area located farther north along the coast from Shantou, in Fujian province. Shantou (Swatow) itself is located in Guangdong near the northeastern provincial border with Fujian.

Zhangzhou
Zhangzhou was for a time a very large production center, and its porcelain wares were predominantly exported to Southeast Asia and Japan. The shipping port was Yuegang (Yue Port), located in the same bay. Yuegang became a major trading port. During the sea prohibition (Ming ban) Yuegang appears to have been one of the smuggling ports in the area, where merchandise was shipped from despite the ban.

Due to civil war and the fall of the Ming dynasty Zhangzhou started to decline in the 17^th century. Although production resumed later, in the Qing dynasty, its never recovered and Xiamen (Amoy) became the center of production in the area.
