Excavation of Testar del Molí, the only workshop found in the Manises-Paterna area, revealed the existence of a fourteenth-century ceramic workshop covering the remains of the thirteenth-century workshop. This study is concerned with the fourteenth-century production, and forthcoming papers will connect both epochs following the findings of current excavations. The chemical and mineralogical characterization of the ceramic production of this workshop shows the presence of three groups of ceramic pastes which could also be distinguished by, and, thus, related to, their daily use. The raw materials found in the excavation have also been mineralogically and chemically characterized, and a model of possible mixtures of raw materials has also been developed in order to determine their possible use in the manufacture of the pottery previously characterized. 相似文献

Lead-glazed pottery from the medieval workshop of Les Olleries Majors (Paterna, Spain) has been studied by Mössbauer spectroscopy, X-ray diffraction, X-ray fluorescence and optical spectroscopy. Yellow, brown and honey-coloured glazes occur on pots glazed on only one surface. They have virtually identical compositions and transmittance spectra, their apparent differences in colour are due to the colours of the underlying pastes. Yellow glazes occur on cream-coloured calcareous bodies, honey-coloured glazes occur on less calcareous bodies with some development of hematite, while brown glazes occur on red siliceous cooking-pots. Green glazes are found on pots glazed on both surfaces; the glazes trapped CO2 evolved by decomposing carbonates, resulting in an internal reducing environment. This caused the reduction of iron to the ferrous state which coloured the glaze green by diffusion. 相似文献

By the 1880s, imperial government's practice of ‘retreating’ to the Indian hill stations for much of the year was well established. Despite the strength of this new tradition, such a relocation of colonial administration never lacked its critics. This paper examines the expanding administrative use of the hill stations from the early nineteenth century through the 1880s. As the nineteenth century ‘scientific’ framework for British control of India was formed, conflicting strategies and practices for maintaining imperial control required mediation and contrasting frameworks for defining duty and loyalty between government and subject vied for dominance. The significance of Utilitarian thought, changing appraisals of climate and constructions of race are evaluated in an analysis of the imperial hill stations. 相似文献
