With ceramics from the 11th to the 19th century, Sjostrand proposes a chronology of wares not available earlier from precisely dated ‘time capsules’ sites.Each of Sjostrand's ten shipwrecks, their cargo composition and detail of the ships structure is presented in this unique "coffee table" book.

Analysis of the recovered cargo however led to ‘about 1625’ as a more likely date for the wreck.was incorporated on the recommendation of the Malaysian authorities.This was done in order to formalize and to expand on the company’s researcher’s extensive knowledge of Asia’s ceramic developments and maritime trade.His meticulous documentation of a series of ten shipwrecks from the 11th to 19th centuries reveals the early dominance of Chinese trade ceramics, a subsequent loss of the Chinese monopoly in the late 14th century when Southeast Asian ceramics entered the market, the basic parameters of the Ming gap shortages of the 14th-15th centuries, and a resurgence of Chinese wares in the 16th and 17th centuries.Just as important, Sjostrand freely shares bring new understanding to ancient ship construction, and his voluminous reading allows him to set the ships and their cargoes in historical perspective.Its two most important elements are a full accounting of the archaeological excavation itself and then an inventory of the artefacts recovered.

Significantly, the artefacts include a major cargo of some 37,000 pieces Chinese kraak porcelain that the authors (after thorough analysis) assign to /- 1625.

The excavation of The Wanli Shipwreck in Malaysia’s territorial waters is only the latest chapter in their joint efforts to illuminate history through projects in maritime archaeology.

The accumulated details of this shipwreck site reveal a surprising and explosive history – the date, the historical circumstances, the mounds of shattered porcelain associated with broken and missing hull planks lead intractably to the theory that the vessel was a Portuguese-managed ship that sank in a sea battle with Dutch forces that were seeking to control the port of Melaka.

This ancient trade started sometime around the 4th century and lasted well into the 19th century.

Following a successful shipwreck discovery, the company obtain a government permit to excavate the wreckage, and then carry out detailed marine archaeological procedures in recovering the artifacts, mapping the ship's remains and securing other data for future research.

After each concluded project and following conservation of recovered artifacts, we search for and pinpoint ruined kiln sites and compare its wasters with the recovered ceramics until we are satisfied we located the place in which the shipwreck pottery was made centuries earlier.
