Underwater archaeological research has been developed less aggressively in Malaysia than in other ASEAN partner countries, such as Indonesia, Thailand, Vietnam, and the Philippines. In past decades, financial constraints have limited the development of underwater archaeology, and the field has been dominated by commercial salvage experts. Malaysia has not addressed many issues or fundamental problems related to future development. The discovery of the Bidong Shipwreck in 2013 has raised hopes that underwater archaeological research in Malaysia will develop more dynamically. The successful excavation of this shipwreck site proves that local experts can conduct scientific excavations. This article presents and discusses the discovery and process of excavating artifacts from the Bidong Shipwreck. The project outcomes provide a guide for stakeholders and agencies involved in future underwater excavations in Malaysian waters.

This study focuses on the characterization, thermal behaviour and firing properties of clays from Cap Bon Basin, Tunisia. Chemical (inductively coupled plasma atomic emission spectroscopy) and mineralogical (X-ray diffraction (XRD), Fourier-transform infrared (FTIR) spectroscopy) characterization of the clays was carried out. Physical properties were identified using particle-size distribution and Atterberg limits tests. Differential thermal analysis/thermogravimetry, dilatometry, XRD and FTIR analyses were conducted to assess the thermal behaviour, transformations and crystalline phase development during firing. The clays studied show large proportions of silt and clay fractions. They are rich in SiO2, Al2O3 and Fe2O3 and mostly consist of illite, kaolinite, smectite and minor mixed-layer illite-smectite. Associated minerals are mainly quartz, calcite and feldspar. To monitor the firing properties, three clay mixtures referred to as M1, M2 and M3 were prepared according to the physicochemical and mineralogical characteristics of the raw clays. These were sintered at 900°C, 1000°C and 1100°C and tested for firing shrinkage, flexural strength and water absorption. As a result, various mineralogical transformations occurred at 900–1100°C associated with the crystallization of new phases. The main transformations identified at >1000°C resulted in the formation of anorthite and mullite, causing significant densification of the fired ceramic materials. Sintering at 1100°C increased the densification and thus improved the flexural strength. At this temperature, the sintered ceramic tiles exhibited excellent properties, namely water absorption of 2–3% and flexural strength of 30–41 MPa, indicating that these studied clays might be used as raw materials for the production of stoneware tile ceramics.

The European colonisation of South America had different effects on the indigenous peoples, particularly on mobile hunter-gatherer societies such as those that inhabited mainland southern continental Patagonia and the island of Tierra del Fuego. The combination of archaeological data with ethnographic and historical accounts shows contrasting contexts for the manufacture of scrapers and projectile points with new raw materials such as glass and stoneware within these two distinct geographic areas. These differences are explained by a number of key factors: the introduction of the horse, the role of guanaco in a newly imposed capitalist economic framework, demographic patterns, bio-geographic barriers and the establishment of ‘reservations’ and missions.

The Hansa formed the principal agent of trade and cultural exchange in northern Europe and the Baltic during the late medieval to early modern periods. Hanseatic urban settlements in northern Europe shared many things in common. Their cultural ‘signature’ was articulated physically through a shared vocabulary of built heritage and domestic goods, from step-gabled brick architecture to clothing, diet, and domestic utensils. The redevelopment of towns on the Baltic littoral over the past 20+ years offers an archaeological opportunity to investigate key attributes of late medieval society on the micro-scale. Such attributes include the development of mercantile capitalism, colonialism, and proto-globalization. For instance, distributions of artefacts now point to the Hansa as an agent of the Reformation movement in northern and western Europe. Where they were once almost exclusively regarded as material evidence for long-distance commercial activity, domestic artefacts, such as table and heating ceramics, are now subject to scrutiny as media for social, cultural, ethnic, and confessional relationships, and combine to create a distinctive Hanseatic material signature. Ceramic case studies illustrate how the archaeology of the Hansa now intersects with the wider historical debate about Europeanisation and proto-globalization arising from the development of long-distance maritime trade from the thirteenth century onwards.
