Mineralogical and Chemical Characterization of Roman Slag from the Archaeological Site of Castra (Ajdovščina,Slovenia)

This study deals with the mineralogical and chemical characterization of archaeometallurgical material from the Roman archaeological site of Castra (Ajdov??ina, western Slovenia). Samples were initially analysed via optical microscopy and X‐ray powder diffraction, with the composition of individual phases then determined using scanning electron microscopy coupled with electron‐dispersive spectroscopy, and Raman microspectroscopy. Chemical investigation was carried out by using inductively coupled plasma atomic emission spectroscopy to measure the major element content. The results showed that the slag originated from iron smithing operations, with calcium‐rich olivines, as well as wuestite and leucite, the most abundant phases. The investigated slags were also found to be characterized by significantly high lime levels, which probably promoted the formation of the calcium‐rich olivines.     

Turquoise Mine and Artefact Correlation for Some Bronze Age Archaeological Sites in Hubei Province,China

In China, there are places that are rich in gem‐quality turquoise resources, including north‐west Hubei Province and the nearby Baihe County in Shaanxi Province, and many ancient mining sites, although the mining history remains a mystery. Based on the compositional data from reference samples of known deposits, a comparison of the major and trace element contents of archaeological turquoise may help with determination of artefact provenance. This paper discusses new evidence of provenance‐tracking of turquoise in this area, obtained from geochemical analyses using REE and other trace elements of 22 turquoises and their surrounding rock samples from six ancient mines and three archaeological sites. The results indicate that the three archaeological turquoises from the tomb of the Middle Spring and Autumn Period (580–560 bc ) and the Warring States Period (476–221 bc ) in Hubei Province were made of raw material from north‐west Hubei Province and the nearby Baihe County in Shaanxi Province. [Correction added on 29 October 2014, after first online publication: In the preceding sentence, the correct dates for the Middle Spring and Autumn Period, and the Warring States Period have been added]     

The Role of Pattern‐Welding in Historical Swords—Mechanical Testing of Materials Used in Their Manufacture

Pattern‐welding is a well‐known technique that was widely employed in the manufacture of swords. While the decorative effect of genuine pattern‐welding (employing phosphoric iron) is indisputable, to date its reinforcing effect is rather unclear. In order to understand this issue better, wrought iron, phosphoric iron, steel and various pattern‐welded samples were prepared and mechanically tested, and the results obtained are discussed in detail. Both the mechanical testing and the long‐term metallographic investigation of medieval swords suggest that pattern‐welding does not have any significant positive effect on the mechanical properties of swords and we should consider it a primarily decorative technique.     

Productive Paradoxes: Exploring Prefigurative Practices with Derrida through a Spanish Food Sovereignty Collective

There has been a proliferation in the use of the concept of prefiguration to describe and understand many of the protest and social change movements of the past decade. However, there are key aspects of the concept that remain unexplored. In this paper I consider telos and justice, and unveil a temporal paradox arising from the thinking behind prefiguration. Rather than this temporal paradox of prefiguration being the undoing of the concept, it does in fact have the potential to be its strength. The purpose of this paper is to assert, by drawing on Derrida’s notion of the impossibility of justice, that the temporal paradox of prefiguration is not something to be resolved but instead is to be foregrounded and navigated. I use research from a food sovereignty collective in the north of Spain to offer an illustration of a prefigurative economic politics that embraces Derrida’s justice-as-an-impossibility.     

Quality turns in Nordic food: a comparative analysis of specialty food in Denmark,Norway and Sweden

ABSTRACT

This article compares the development of specialty food in Denmark, Norway and Sweden using a number of quantitative indicators as well as a qualitative analysis of government policy. The analysis shows that specialty food has increased in importance in all three countries over the last twenty years, but there are important differences in the kind of specialty food that has developed and the nature of government intervention and governance structures. Overall, Sweden appears to have the largest production of specialty food and drink and is particularly strong in organic production and consumption, farm processing and farm shops. Norway has a large number of products with protected origin and also leads in the number of farmers’ markets. Denmark lags behind the other countries on most indicators, but has witnessed the fastest growth in microbreweries over the last five years. Theoretically, the article challenges the ‘negative’ definition of specialty food as ‘non-industrial’ or ‘alternative’, and suggests a more nuanced approach. Empirically, it points towards the possible existence of a ‘Scandinavian model’ of specialty food governance with extensive interaction between central government, local government and private firms to stimulate the growth of specialty food.     

It’s never too late to join the revolution! – Enabling new modes of production in the contemporary Danish food system

ABSTRACT

The Danish food system has undergone a transition in the past 10–20 years, in which new quality conventions have evolved. Examples include increasing organic production and consumption, and increasing interest in local food, experience, community, taste and gastronomy. This article explores what influences if and how these new food trends are expressed in the food system. We conduct a comparative case study involving three product categories: craft beer, specialty flour and organic broilers. Craft beer and specialty flour have undergone a revolution, in which new flavours, products, practices and social relations are generated; by contrast, organic broilers have remained a relatively stable product category. The case studies demonstrate that the revolution is not just taking place in one domain, but it implies a multidimensional reconfiguration of the food system where an emphasis on multiple quality aspects and diversification of the product category is important. However, food trends are not the invention of the individual producer, but serve as common conventions that products can be related to, although their interpretation is not pre-given. In addition, a transition presupposes a shared vision and a coordination of activities among the actors in the food system or the mobilization of new actors who share this vision.
