Full textThe study of the ancien metal working in the bulkiemde province is a wide approach to the history of iron in the central west region of the Moose plateau in Burkina Faso. We have based our study on data from various disciplines such as history, archeology, ethnology and metallograpy to analyse an ancient iron and steel warking which has disapeared since the colonial period because of the new economic requirements and of the introduction of the generative iron. We have studied two different types of metal working. This one of the present time populations which we have studied by collecting oral sources and this one of the antique populations who formerly occupied this area and who are only identified through archeological relics. The are scarcely no written sources about them. The result is that both iron and steel working are not the same. The foundations of the furnaces collected during the escavations and the metallographical analyses, proved this difference

Full textThe surveys carried out in the extreme north of Burkina Faso have led to the identification of more than 150 metallurgical sites.Two production periods have been distinguished, based on the type of slag-pit furnaces. During the first one (7th–10th c.), the production was probably restricted to the local market. During the second period (11th–13th c.), it multiplied by 25.Most of workstations are situated in the Beli River’s valley, in the North zone, but there are very tight links with settlements of the South zone, where the iconographic themes of rock engravings help to characterize the local population. It was a hybrid society, basically Sudanian with Berber influence and a Muslim varnish. The geographic distribution of a specific type of slag-pit furnace allows to locate its territory between the Niger River’s valley and the ancient springs of the Beli River.Arab-Muslim texts allude regularly to a limit of the Islam World at bilād al-Sūdān. It is argued that his symbolic boundary was situated south from Kukia / Bentia. It overlaps with geologic, climatic and cultural limits. Beyond is the world of animism, the land of gold and iron.Situated precisely in between those two worlds, this society could have been both a strategic and commercial go-between

Full textBurkina Faso, like other African countries, experienced a primary iron metallurgy millennia ago. In the current researches, the earliest date is around the eighth century BC, in the Bwamu at Douroula, in western Burkina Faso. In almost all regions of the country, vestiges relating to the former iron production are visible and are now tangible witnesses of knowledge and the ability of ancient metallurgists. Bam province, our study area is located in the region of north-central Burkina Faso and covers an area of 3931 km2. Our archaeological surveys have enabled to identify more than a hundred sites and remains resulting directly from the steel production. Ethno historical, archaeological and archaeometric investigations of these remains have elucidated the origins of the steel industry in this part of Burkina Faso and permitted to characterize the technical traditions that were used by the ancient metallurgists. Thus, five technical traditions have been identified and described (B1, B2, B3, B4, B5). They have been developed at different times. Besides the technical aspects, socio-cultural and economic implications caused by the local iron industry were apprehended to better understand the place occupied by the iron artisans in the traditional society of Bam province

Full textThe purpose of the present work titled knowledge and know-how of ancient metallurgists : interdisciplinary researches on ancient techniques of ironwork among the Bwamu (Burkina Faso-Mali) is to study the processes of direct iron metallurgy in the West African region of the Bwamu. It is articulated around three parts : we start off by focusing on the artefacts of metallurgical activities in their proper archeological, socio-cultural and historical contexts. In this respect, we highlight the most characteristic particularities of the direct iron metallurgy which serving as object of our analysis. The second part of the work essentially deals with the technical aspects of the different phases composing the chain of operations in direct iron metallurgy : mining research, reducing metallurgy, and the processes of ancient smithy. Ultimately, the third articulation of our analysis focuses on the social and economical history of mines more generally, as well as that of iron in particular. This part stresses on the position and role of iron craftsmen, metallurgists and blacksmiths-the Kaani - in ancient rural societies. We may conclude by stating that the present study primarily evolves around the topic of the technical particularities and specificity of direct iron metallurgy in the Bwamu

Full textThis thesis proposes a synthesis of the archaeological data in Tusian space (Western Burkina Faso). Its purpose is to study material linked to the human presence in this area. Based on an approach that combines archeology, ethnography and anthropology this study is organized around the analysis and interpretation of archaeological remains. The sources used are: written documents, oral and archaeological sources. The issue revolves around two questions: the archaeological record of the tusian country and the contribution of the artifacts to the history of the people and the territory. The work is divided into ten chapters divided between three parts. The first situates the methodological framework and the study area. The second part is devoted to the study of archaeological sites and the third part presents archaeological objects. This thesis highlights new materials for the history of tusian space. It also contributes to the improvement of the archaeological and historical knowledge of this area. The study identified caves and shelters, anthropic mounds, sites for specific activities (metallurgy, Wickerwork, burial). The archaeological objects consists of potteries, polished stone axes and adzes analyzed from the morphological, typological and functional point of views. To these tools are added grinding wheels and other grinders still in use. The study of the rock art of the area is characterized by an attempt to locate sites of engravings, the identification of the different shapes and the techniques of engravings. Concerning the ancient metallurgy of iron, the study proposes an inventory of the main artifacts based on typology, chronology and spatial distribution

Full textThis work describes the thermal transformation and the sintering process at low temperature (1100°C) of ceramic compositions based on a selected kaolinitic clay from Burkina Faso. It is a very representative clay among those used in this country for the traditional manufacturing of pottery and brick wares or roof tiles. This clay was used as it or mixed with calcite to improve the properties the fired products. The chemical and mineralogical compositions of the clay were analysed as the structural characteristics of the kaolinitic phase, which include all the iron impurity in octahedral sites. The study of thermal transformations of the clay reveals typical thermal transformations very similar to that of a low crystallized kaolinite mineral. Thermal transformations and sintering processes were studied in more details to identify and quantify the mechanism involved, but for the dilatometry characterizations, the intrinsic material behaviour must be separated from the experimental results. We also study the clay-calcite mixes because they proved to increase the mechanical strength of products sintered at low temperature. Since 950°C, these mixes become recrystallized through a reaction- sintering mechanism, which follows a particular crystallization path : metakaolinite-gehlenite-anorthite. These crystallized phases are under the form of small nodules embedded in a silico-aluminate matrix, which is porous and weakly structurally organized. The crystallographic study of the transformation path of phases revealed specific structural transformations with preferential mutual orientations of cristallographic directions and the maintain of calcium atom positions. The mechanical strength of the sintered materials is controlled by the very heterogeneous character of the microstructure. In general, a three dimensional network of anorthite particles are partially interconnected in the matrix phase. The occurence and repartition of connections influence the mechanical properties, together with the porosity of the matrix phase

Full textIn contexts where micronutrient deficiencies are a major public health concern, the improvement of the retention and bioavailability of iron and zinc in dishes frequently consumed by young children could be part of a food-based strategy to combat these deficiencies. A food consumption survey using weighing records was carried out on 630 children from 6 to 36 months in Burkina Faso. This permitted to highlight the main characteristics of the children diet. Iron and zinc intakes were far below the recommended intakes. High fibre and phytate intakes were also observed. More than 90% of the young children consumed millet, sorghum or maize in the day of the survey. A detailed monitoring of the traditional processing of the cereal dishes permitted the identification of the main unit operations that could have an effect on iron and zinc content and bioavailability. Important losses in iron content (50% in millet for 10% DM loss) and zinc (23% in sorghum for 7% DM loss) were observed after traditional dehulling, either manual or mechanical. Biofortified varieties showed similar behaviour but their phytate/zinc molar ratio was still improved. During milling in local mill with grindstones, iron contamination occurred, and tripled the initial iron content. But the bioaccessibility of this contaminant iron was very low. The acceptability of the biofortified varieties of millet, tested on various dishes, was lower than that of the local variety. The improvement of the processing methods combined with the use of biofortified varieties could be advantageously promoted to contribute to alleviate iron and zinc deficiencies
