The skills and techniques of past metal smiths are gauged through the analysis of the microstructures of artifacts using standard metallography. Little or no work has been carried out to test or verify microstructural observations through ethnographic and experimental re-enactment of techniques. This study will offer a way to establish the veracity of this approach to studying iron objects and will draw on direct practical engagement with remnant Keralan blacksmithing communities. In addition, controlled experimental re-enactment, deconstruction of techniques and comparative microstructural analysis will be carried out. How local agricultural tools are forged and what makes up the smithing toolkit will be assessed as well as how each forging space is utilized. This research aims to conduct the study using a range of methods that includes experimental re-enactment in a manner that assesses their applicability to other regions and periods.

This thesis studied the iron smelting technology of Southwest China. It introduces the natural and human environment of Southwest China and gives a systematic review on the important archaeological sites of Southwest China. A total of 75 iron smelting related sites of Southwest China were surveyed. Five of these sites were excavated and studied in detail including the furnace structures, smelting related materials and their smelting process. A statistical study of over 5,100 iron objects (and bronze and iron bi-metallic objects) in published excavation reports was carried out to understand the pattern and statistical distribution of iron objects excavated in Southwest China. This was followed by metallographic analysis of 66 samples taken from 42 iron objects and slags (mostly from the Lijiaba site, and from the Qiaogoutou site). The slag samples (from the Xuxiebian site) helped to identify the bowl-shaped furnaces, that discovered at the iron smelting sites of Southwest China, as refining furnaces. The results of the metallographic studies helped to characterise the range of technologies that developed in Southwest China primarily during the Han dynasty (202BC-220AD). According to these studies, some issues such as the origin and development of technology, the labourers’ identities, the origin of the blacksmiths, and the management and policy of iron production in Southwest China are discussed.

The innovation of crucible steel, a high-carbon, homogeneous, slag-free steel, is regarded as a milestone in the history of the development of ferrous metallurgy. Associated in popular literature with the making of swords, particularly in the Early Islamic period, crucible steel, also known as wootz, possesses exceptional properties of hardness and strength. While much is now understood about its metallurgical composition and structure, little is known of its origins and spread. Few archaeological sites have been uncovered and to date pre-industrial production of this alloy is only known from Central Asia and South Asia. Previous studies have largely focused on individual sites in isolation from wider regional patterns of ferrous metallurgy. As a refining process of iron, it is argued here that crucible steel has a symbiotic relationship with the smelting technologies that produced the raw material for refining. This thesis explores the value of assessing crucible steel production within its wider landscape, cultural and technological context by presenting the evidence from Northern Telangana, India. Historical sources and recent archaeological field surveys have shown that Telangana has a rich metallurgical past, including the manufacture of crucible steel. Despite this, little archaeological work has been conducted in the region to elucidate the nature, scale and diversity of the metallurgical technologies that underpinned its production. Following a major reconnaissance survey in 2010 by the Pioneering Metallurgy Project, the present study tackled the assessment of the large body of field data and the recording of the technological waste assemblage collected. By combining detailed morphological analyses of the collected materials and contextual information recorded during field survey, a better understanding of the techno-cultural role of crucible steel was gained. Technological variations were identified across the survey area and the inter-relationship between iron smelting and crucible steel was assessed. The study reveals that crucible steel was embedded within a long-established local and regional tradition of iron smelting and concludes that it represented the intensification of a pre-existing iron processing industry. The evidence points to a widespread crucible steel production industry with varying degrees of site specialisation, indicating that it was perhaps more common than the few isolated sites commonly referred to in the literature suggests. The comparison of the material evidence with other production sites in Central and South Asia also revealed close parallels to the latter suggesting that they belonged to the same regional manufacturing tradition.

Ethnoarchaeological research of indigenous iron-working in Africa and, more recently, in parts of Asia, has attempted to interpret past technology through the lives and memories of blacksmiths and smelters. In India, recent archaeological and historical research of iron-working and other forms of craft production has examined the social position of specialized craft producers within regional caste-structures. This thesis incorporates both these approaches to study traditional iron-working communities in northern Telangana, a region in south-central India. Anthropological theories of craft production and power are employed to provide a nuanced interpretation of the archaeometallurgical and ethnographic data from the study area. Medieval travelogues and colonial documents attest the presence of a thriving preindustrial iron and crucible steel-manufacturing tradition in northern Telangana. Initial archaeological and historical investigations in the region by Lowe (1989) and Jaikishan (2009) identified a significant number of sites related to early iron and crucible steel production. The Pioneering Metallurgy project of 2010 (Juleff et al., 2011) surveyed within the four districts of northern Telangana to investigate the origin and development of these technologies. Besides locating and recording archaeometallurgical evidence, the project also conducted ethno-metallurgical enquiries to record the members of rural blacksmith communities at work. This highlighted the potential for an in-depth ethnoarchaeological study to understand the socio-cultural context of these indigenous technologies by unraveling the lives of the descendants of iron-smelters and steelmakers of northern Telangana. This was the starting point of the present research project. My research investigates a dynamic set of relationships between craft, people and space—physical and social. The ethnographic data for this research is collected through 63 formal and numerous informal interactions with the iron-workers of the region. These interactions and other collected data are presented in appendices. The lives of five practitioners with different specialized skills provide the entry point into this research which is presented in two-parts. After setting the background, Part A investigates the intricate relationship between indigenous smelting technologies, smelters and place. Based on interactions with older members of the Mudda Kammari (smelter) community, this study attempts to reconstruct the practices of iron-smelting from their individual and collective memory. Where possible, elderly smelters led me to the rivulets where ore was mined and showed the surviving pits for preparing charcoal, while explaining technological details. The spatial locations of these were recorded and analyzed in relation to the smelting sites and present habitations of the Mudda Kammari (smelter) communities. Apart from technological detail, their memory also provided insight into the social and economic networks in which indigenous iron-smelting operated. The demise of indigenous iron-smelting in the first half of 20th century compelled the Mudda Kammari to adopt blacksmithing on a full-time basis. As a result they lost their distinct smelter-identity. A host of specialist iron-working groups like the scissors-smiths, sword-smiths and firearm makers in the area also lost their specialized skills and distinct identities faced with competition from industrial products and government prohibition onthe domestic weapon manufacturing industries from the 1950s. All of these groups were obliged to take up manufacturing agricultural products, and therefore, became homogenized as Kammari (blacksmiths). Lopsided agrarian development, marketization of harvests and recent mechanization of agriculture have ruptured the traditional relations of exchange between the Kammari and the agrarian community. This has significantly reduced the demand for their services, and resulted in displacement of their craft and lives. Consequently, the identity and position that the Kammari enjoyed in rural social space and reinforced through cult performance has degenerated. This led to a further homogenization of artisan identities, supported by a new eclectic identity narrative, which replaced the older, individual craft-community focused identities. Part B of this research deals with this homogenization process in detail. It interrogates the relationship between the decline in craft and the evolution of artisan identity. Based on ethnographic fieldwork and archival studies, this section examines how identities of ironworking communities in northern Telangana are reconstituted and articulated over time with the enfeeblement of their craft. In the final section of the thesis I bring the diverse data together to form a nuanced understanding of the social, cultural and economic context of iron working in northern Telangana. Based on the complexity of iron-worker identity in northern Telangana, this section cautions against drawing straightforward ethnographic analogies to study the archaeological record. I conclude by proposing how this research can benefit future ethnoarchaeological research of craft production and in studying traditional craft and craftsmen in a growing market economy.
