"There is a fall in Chinese market share to only 30-50% when the shipwreck record picks up again for the years 1368 to 1424-30, that is from the beginning of the Ming ban to the end of treasure ship voyages of Zheng He." The Chinese exports fall still lower in the finds that cover the years from 1424-30 to 1487, accounting for only 5% of the ceramic cargoes. 1488-1505," when restrictions on exports are relaxed.
The 60 years after that show mild shortages of Chinese products, but by 1573 the Chinese have reestablished their old monopoly of the ceramic trade in the region.
"It was mainly off-shore oil drillers, who had the equipment and the skills." Divers are locating about 6 new shipwrecks every year, she said.
And many of these wrecks contain not shards as in land sites but thousands of entirely undamaged plates and bowls.
At the Manila Trade Pottery Seminar in 1968 archaeologists generally agreed that there was probably a sharp cutback in Chinese exports to Southeast Asia from the 14th to the 16th century, but that this could not be proved because land sites overlapped too much in time and space.
"The problem could not be solved by land archaeology," Brown said.
Roxanna Brown was introduced by UCLA art historian Robert Brown (no relative), who described her as "one of the two or three people who created the field of Southeast Asian ceramics." Roxanna Brown's special interest is the fourteenth, fifteenth, and sixteenth centuries, high points of Asian plate and vase making arts.
"There is not good evidence for the period just before the beginning of the Ming," she said.

Some 40 years after Tom Harrisson coined the phrase Ming Gap, during which the term came to mean many things and was actually little used, "Finally, there is enough data from shipwrecks to begin tackling the idea of market cycles in trade ceramics." Roxanna Brown has spent the last several years examining the recovered cargoes of many of the recently discovered wrecks, looking at many items to establish the rough date when each ship went down.
Since ceramics were a major trade item throughout this period she has then been able to review each cargo to see whether the traditional dominance of Chinese wares held or if the Chinese plates were absent, replaced by native Southeast Asian manufactures from Thailand, Vietnam, or Malaysia.
Not every decade is documented by a useful cargo, but fifteen of the ships fill in much of the first 140 years of Ming reign. 1470)Lena Shoal/Santa Cruz/Brunei (1488-1505)Ko Samui/Xuande/Gujangan (1506-1521) The Ming Gap was real, Roxanna Brown said.
