The Early Medieval Cutting Edge of Technology: An archaeometallurgical, technological and social study of the manufacture and use of Anglo-Saxon and Viking iron knives, and their contribution to the early medieval iron economy Volume 1 Eleanor Susan BLAKELOCK BSc, MSc Submitted for the degree of Doctor of Philosophy Division of Archaeological, Geographical and Environmental Sciences University of Bradford 2012 Abstract The Early Medieval Cutting Edge of Technology: An archaeometallurgical, technological and social study of the manufacture and use of Anglo-Saxon and Viking iron knives, and their contribution to the early medieval iron economy Eleanor Susan Blakelock A review of archaeometallurgical studies carried out in the 1980s and 1990s of early medieval (c. AD410-1100) iron knives revealed several patterns (Blakelock & McDonnell 2007). Clear differences in knife manufacturing techniques were present in rural cemeteries and later urban settlements. The main aim of this research is to investigate these patterns and to gain an overall understanding of the early medieval iron industry. This study has increased the number of knives analysed from a wide spectrum of sites across England, Scotland and Ireland. Knives were selected for analysis based on x-radiographs and contextual details. Sections were removed for more detailed archaeometallurgical analysis. The analysis revealed a clear change through time, with a standardisation in manufacturing techniques in the 7th century, and differences between the quality of urban and rural knives. -
Centre for Archaeology Guidelines
2001 01 Centre for Archaeology Guidelines Archaeometallurgy Archaeometallurgy is the study of metalworking structures, tools, waste products and finished metal artefacts, from the Bronze Age to the recent past. It can be used to identify and interpret metal working structures in the field and, during the post-excavation phases of a project, metal working waste products, such as slags, crucibles and moulds.The technologies used in the past can be reconstructed from the information obtained. Scientific techniques are often used by archaeometallurgists, as they can provide additional information. Archaeometallurgical investigations can provide evidence for both the nature and scale of mining, smelting, refining and metalworking trades, and aid understanding of other structural and artefactual evidence.They can be crucial in understanding the economy of a site, the nature of the occupation, the technological capabilities of its occupants and their cultural affinities. In order that such evidence is used to its fullest, it is essential that Figure 1 Experimental iron working at Plas Tan y Bwlch: archaeometallurgy is considered at each stage of archaeological projects, removing an un-consolidated bloom from a furnace. and from their outset.

Beyond Wayland – Thoughts on Early Medi- Eval Metal Workshops in Scandinavia
Beyond Wayland – thoughts on early medi- eval metal workshops in Scandinavia Ny Björn Gustafsson ABSTRACT: This paper reflects on and summarises the current state of research on early medieval (750-1100 AD) metal workshops in Scandinavia by way of examples from workshops and metalworking sites recovered via archaeological excavations and surveys over the last 30 years. A critique is presented of a number of features which occur perennially in Scandinavian archaeometallurgical presentations, such as the tendency to overemphasise the importance of written accounts and the common habit of over-interpreting archaeometallurgical finds. Introduction The use of metals in past ages is a subject of seemingly endless possibilities in terms of research and publica- tions – Scandinavia is no exception. It is explicitly or implicitly included in most academic works within the fields of Iron Age and early medieval studies, but as with so many other important and fundamental cultural features, it is more or less taken for granted – as if the extraction and working of metals took place almost on its own. The situation was of course much more complex than that, and this paper aims to highlight some aspects of one of the fundamental prerequisites for metalwork- ing – the workshop. The workshops and production sites listed below have mainly been found within the bound- aries of modern day Sweden, but some important sites in Denmark, Norway, Finland and Estonia have been included (Fig 1). The timeframe is that of c750-1100 AD, often referred to as the Viking Period. The ever-productive forge of myth and legend In many studies of early medieval Scandinavia, the working of metals is mainly presented as taking place under the ever-watchful eyes of masterful smiths. -
From Bloomery Furnace to Blast Furnace Archeometallurgical Analysis of Medieval Iron Objects from Sigtuna and Lapphyttan, Sverige
EXAMENSARBETE INOM TEKNIK, GRUNDNIVÅ, 15 HP STOCKHOLM, SVERIGE 2019 From Bloomery Furnace to Blast Furnace Archeometallurgical Analysis of Medieval Iron Objects From Sigtuna and Lapphyttan, Sverige ANDREAS HELÉN ANDREAS PETTERSSON KTH SKOLAN FÖR INDUSTRIELL TEKNIK OCH MANAGEMENT Abstract During the Early Middle Ages, the iron production in Sweden depended on the bloomery furnace, which up to that point was well established as the only way to produce iron. Around the Late Middle Ages, the blast furnace was introduced in Sweden. This made it possible to melt the iron, allowing it to obtain a higher carbon composition and thereby form new iron-carbon phases. This study examines the microstructure and hardness of several tools and objects originating from archaeological excavations of Medieval Sigtuna and Lapphyttan. The aim is to examine the differences in quality and material properties of iron produced by respectively blast furnaces and bloomery furnaces. Both methods required post-processing of the produced iron, i.e. decarburization for blast furnaces and carburization for bloomeries. These processes were also studied, to better understand why and how the material properties and qualities of the items may differ. The results show that some of the studied items must have been produced from blast furnace iron, due to their material composition and structure. These items showed overall better material quality and contained less slag. This was concluded because of the increased carbon concentration that allowed harder and more durable structures such as pearlite to form. The study also involved an investigation of medieval scissors, also known as shears, made from carburized bloomery furnace iron. -
Bloomery (Edited from Wikipedia)
Bloomery (Edited from Wikipedia) SUMMARY A bloomery is a type of furnace once widely used for smelting iron from its oxides. The bloomery was the earliest form of smelter capable of smelting iron. The result of using a bloomery is a mass of iron and slag called a bloom. This is called sponge iron, because it is porous like a sponge. Sponge iron is usually refined into wrought iron. Bloomeries are no longer used in smelting, because blast furnaces are better. HISTORY China China has long been considered the exception to the general use of bloomeries. It is thought that the Chinese skipped the bloomery process completely, starting with the blast furnace and the finery forge to get wrought iron: by the 5th century BC, metalworkers had invented the blast furnace. Sub-Saharan Africa Smelting in bloomery type furnaces in West Africa and forging of tools appeared by 500 BC. Medieval Europe Early European bloomeries were relatively small, smelting less than 1 kg of iron with each firing. Progressively larger bloomeries were constructed in the late fourteenth century, with a capacity of about 15 kg on average, though exceptions did exist. The use of waterwheels to power the bellows allowed the bloomery to become larger and hotter. European average bloom sizes quickly rose to 300 kg, where they leveled off until the demise of the bloomery. As a bloomery's size is increased, the iron ore is exposed to burning charcoal for a longer time. When combined with the strong air blast required to penetrate the large ore and charcoal stack, this may cause part of the iron to melt and become saturated with carbon in the process, producing unforgeable pig iron which requires oxidation to be reduced into cast iron, steel, and iron. -

This optional science module will provide students with an overview of the development and spread of mining and metallurgy within their natural and archaeological contexts from the Neolithic up to the Industrial Revolution. It includes an introduction to metals as materials, and how the exploitation and understanding of different metals evolved over time in different regions. Particular emphasis is placed on the understanding of technical processes related to metallurgy, their reconstruction based on the study of archaeological remains, and their interpretation in the relevant social and cultural contexts. The course does not focus on the typological or stylistic study of metal artefacts, nor does it attempt an exhaustive documentation of sites and dates (these aspects can be explored by students in their coursework, depending on their specific interests). While copper/bronze and iron/steel take centre stage as the most important metals, individual sessions will address the less common metals such as lead, silver, zinc, brass and gold. -

Hunter-Gatherer Metallurgy in the Early Iron Age of Northern
Antiquity 2021 page 1 of 16 https://doi.org/10.15184/aqy.2020.248 Research Article Hunter-gatherer metallurgy in the Early Iron Age of Northern Fennoscandia Carina Bennerhag1, Lena Grandin2, Eva Hjärtner-Holdar2, Ole Stilborg3 & Kristina Söderholm1,* 1 The History Unit, Lulea University of Technology, Sweden 2 The Archaeologists, National Historical Museums, Sweden 3 Archaeological Research Lab, Stockholm University, Sweden * Author for correspondence: ✉ [email protected] The role of ferrous metallurgy in ancient communi- ties of the Circumpolar North is poorly understood due, in part, to the widespread assumption that iron technology was a late introduction, passively received by local populations. Analyses of two recently exca- vated sites in northernmost Sweden, however, show that iron technology already formed an integral part of the hunter-gatherer subsistence economy in Nor- thern Fennoscandia during the Iron Age (c. 200–50 BC). Such developed knowledge of steel production and complex smithing techniques finds parallels in contemporaneous continental Europe and Western Eurasia. The evidence presented raises broader ques- tions concerning the presence of intricate metallur- gical processes in societies considered less complex or highly mobile. Keywords: Circumpolar North, Fennoscandia, Iron Age, iron technology, hunter-gatherer subsistence Introduction The introduction of iron technology to the Circumpolar North has been a neglected topic of archaeological research and considered peripheral to Old World ferrous metallurgical devel- opments (Wertime 1973; Pleiner 2000). The region has typically not been included in broad narratives of prehistoric iron technology, and it is generally accepted that the latter was estab- lished much later in this region than elsewhere in Eurasia.
