Date: December 1, 2017
Speakers and Topics:
Mr. Chhay Rachna (Angkor Ceramic Unit,
APSARA Authority, Siem Reap, Cambodia)
Topic: Understanding the Context of Khmer
Ceramics and Kilns and their Association with Cross-Cultural Exchange
Dr. Ellen Hsieh (Cotsen Institute of
Archaeology, UCLA)
Topic: Non-invasive Scientific Analysis on
Trade Ceramics from Consumption Sites and Shipwrecks
Dr. Brian Fahy (The Oxford Centre for
Maritime Archaeology, University of Oxford)
Topic:Seeing the Forest for the Trees: A Holistic Study of Southeast Asian Shipwreck AssemblagesCeramics has always been one of the main focuses in the field of maritime archaeology. On 1st December 2017, a Roundtable Workshop was held by our department, inviting three guest speakers to share their thoughts on maritime archaeology and ceramics. We had Mr. Chhay Rachna from Angkor Ceramic Unit, APSARA Authority, sharing on Khmer ceramics and kilns and their connections with other Southeast Asia cultural groups; Dr. Ellen Hsieh, from Cotsen Institute of Archaeology, University of California, Los Angeles, talked about non-invasive scientific analysis on trade ceramics found in shipwrecks and consumption sites; Dr. Brian Fahy, from The Oxford Centre for Maritime Archaeology, University of Oxford, presented his arguments on the essentiality of establishing a holistic study of Southeast Asian shipwreck assemblages.

Khmer ceramics
produced in the Angkorian period were only for local use, suggested by Mr.
Chhay, while relations and interactions with outer regions lied within the economy
of ceramic imports. Mr. Chhay studied the Khmer interactions with other regions
in ceramics during the Angkorian period by comparing ceramics found in the
production sites and consumption sites, and evidence from terrestrial
archaeological sites beyond Khmer Empire and Southeast Asian shipwrecks.
The presentation
mainly focused on three primary stoneware ceramic production sites, namely the
Angkorian core region group (Group I), provincial Angkorian production centre (Group II), and late Angkorian
production centre (Group III). The
ceramics in Group I are mainly green glazed and unglazed. White clay was used
to make small glazed containers, while grey clay from the nearby source was
used to make unglazed ceramics. Stoneware excavated in kilns of Group I ranges from roof tiles to boxes,
bottles, pots, plates, large jars and large basins, with diverse patterns
incised by potters. For Group II, most of the ceramics found were brown glazed
and dark green glazed, made of red clay, and supported by regular fire clay
inside the kilns differing from irregular fire clays found in Group I. Most of
the stoneware found in Group III were likewise brown glazed, produced in kilns
with structural elements similar to those in Group II.
Mr. Chhay argued,
these Khmer wares were for daily use, commonly excavated in various consumption
sites, while imported Chinese ceramics tended to be more precious, bulk of
Chinese ceramics assemblages were rare to be found outside the Greater Angkor
Region which is the elite context. For instance, in Prei Monti Temple in Roluos,
which was the early Angkorian site from the 9th Century, 17.5% of
excavated ceramics were imported, with 73.6% Khmer earthenware and 8.9% Khmer stoneware.
There were Chinese ceramics and ceramics from other countries found in
archaeological sites that are located in Greater Angkor Region, but no Khmer
ceramics was found in both terrestrial archaeological sites beyond Khmer Empire
and Southeast Asian shipwrecks. By comparing ceramics in production sites and
consumption sites and evidence from shipwrecks, Mr. Chhay proposed that ceramics
from the mentioned three sites were for local consumption; the relations and
interactions with outer region were found to be in the import trade as abundant
ceramics from other regions were found in elite consumption sites.

Archaeologists
face various challenges when they adopt prevalent methods to identify ceramics.
There are visual analysis, which includes the observation of the types, forms,
glazes, pastes and decorative patterns of ceramics, and scientific analysis,
such as the study of chemical composition, crystallization process and
weathering process. The visual analysis did not serve well for archaeological
research, which often involves dirty, broken, tiny sherds with no decoration,
while scientific analysis requires sophisticated invasive laboratory instruments
which are not suitable for the large quantity of sherds or to be used on site,
given the time and money they cost, and the damages they made on the sherds. In
response to these problems, Dr. Ellen Hsieh proposed non-invasive portable
X-ray fluorescence (pXRF) and fiber optics reflectance spectroscopy (FORS) for
the identification of ceramics in archaeological context. The presentation
mainly focused on the application of pXRF, and the pXRF patterns of chemical
elements in blue pigments and white areas on ceramics produced in Jingdezhen,
Zhangzhou from China and Hizen from Japan were shown. Dr. Hsieh analyzed the pigments
of blue-and-white ceramics found on Santa Cruz shipwreck from the Philippines with
pXRF and identified them to be produced in Jingdezhen by comparing the data
which the compositional pattern of pigments in Jingdezhen ceramics found to be
highly matched with those on Santa Cruz, showing cobalt-based blue pigments,
with poor Iron and rich Manganese. Dr. Hsieh presented her application of non-invasive
technology in identifying ceramics and argued that this provides new possible
ways to see global networks from chemical composition.

A ceramic-centered
narrative is not enough to understand a shipwreck, argued by Dr. Brian Fahy,
who agreed the importance of ceramics but also other often-neglected materials
that could be found on shipwrecks. Dr. Fahy studied the materials that were excavated
in six Southeast Asian shipwrecks and sites, namely Turiang, Bakau, Rang Kwien,
Ko Si Chang III, Lena Shoal, and Santa Cruz. These materials include iron sand,
tin ingots, Chinese coins, manufactured materials such as mirrors, armaments
such as lantakas, sword and spearhead, net weight, fishing hook, duck
egg, aniseed, peppercorns, minerals,
beads, grinding stone, earthenware, and so forth. The study of these materials
can serve for a better understanding of the social, economic and political
context of the past. For instance, the rosette on the tin ingots found on
Turiang, a shipwreck near to Malaysia, corresponds to the pattern on the money used in Malaysia. What does this
phenomenon imply? What is the significance of the pattern? This may need
further study, but it shows how these materials play a role in facilitating us
to understand the past. With the consideration of the aforementioned materials,
Dr. Fahy argued that it will give us a more complete
picture of the networks as established by the ships back then.
