Aragonese Tiles in a Flemish Castle: A Chivalric Gift-Exchange Network in Fifteenth-Century Europe

Excavation of the mid-fifteenth-century castle of Pieter Bladelin, a high-ranking Burgundian official, in the village of Middelburg-in-Flanders, near Bruges (Belgium), has unearthed a remarkable series of blue and white painted and glazed floor tiles. Post-excavation archival and heraldic inquiries into the tiles has led to a deeper understanding of the role that gift exchange of luxury objects played within the diplomatic network of Alfonso V “the Magnanimous”, King of Aragon, and Philip “the Good”, Duke of Burgundy, in shaping a shared chivalric and crusading culture between Burgundy and Aragon. The study demonstrates the added value of the integration of archaeological and historical data in studying economic, political and cultural processes for the later medieval or early modern period.

从汉代瓦当“四神”图形解读秦汉的造型艺术

汉瓦当“四神”图形在秦汉时期社会生活中广泛应用,它的造型艺术可以使我们清楚地看到秦汉时代造型艺术风格特点：创造性地利用“适合造型”;以“炉火纯青”的造型艺术语言创造了“经典”的“四神”形象;运用夸张和变形的造型手法来“抒情写意”;对传统神灵形象的升华和再创造。它表现出一种时代和民族的生机勃发的艺术精神和本质。     

激光重熔Al2O3+13%wt.TiO2-SiC纳米复合陶瓷涂层组织

采用激光重熔等离子喷涂陶瓷涂层技术，以纳米SiC材料为填料，在45钢表面，制备了Al2O3＋13％wt．TiO2-SiC纳米复合陶瓷涂层。用X射线衍射、扫描电镜研究了纳米SiC复合陶瓷涂层的微观组织结构。结果表明，重熔层由仪-Al2O3、TiO2、Si、SiC以及新相Al4C3组成。在激光的作用下，原等离子喷涂层的片层状组织结构得以消除；纳米SiC颗粒填充在大颗粒Al2O3或TiO2之间。     

利用铝厂污泥研制陶瓷无光釉

本文利用铝型材厂污泥为原料,配制陶瓷无光釉,属固体废弃物综合开发利用项目。实验结果表明：污泥用量可高达10％-20wt％,配方中随着污泥含量的增加,釉面由光泽逐渐地转变到亚光直至无光。为使组成稳定,防止釉面开裂,污泥必须先经过干燥、预烧后再投入使用,污泥的最佳预烧温度为1200℃。     

Technical replicas of Portuguese ceramic tile bodies produced in the Oporto region in the late nineteenth to early twentieth centuries

Portugal is well known for its facades decorated entirely with ornamented glazed ceramic wall tiles called azulejos. On ageing, the tiles may detach and fall off, or deteriorate to such an extent that it becomes necessary to replicate them. Hence tile replication is a common practice in Portugal for façade restoration, but very often these new tiles do not have the same physical and/or chemical properties as the original ones. Such differences might be a factor in differential deterioration of the façades after restoration. One step toward an improvement in compatibility is to make new ceramic bodies with the same characteristics as the original ones. This study focuses on two types of glazed ceramic wall tiles from the Oporto region in Portugal: ‘calcic faience’ and pó de pedra. A total of 25 samples from the late nineteenth to early twentieth centuries were studied systematically as an attempt to improve knowledge of these materials and to create a basis for their replication. All samples were collected from facades that were under conservation/restoration at the time when sampling was performed. The original traditional ceramic bodies were analyzed by X-ray diffraction and X-ray fluorescence. Total open porosity, capillary absorption coefficient, and mercury intrusion porosimetry were also measured in order to gain knowledge on their physical characteristics in addition to their chemical and mineralogical compositions. High-temperature crystalline phases such as diopside, gehlenite, and mullite were found in the calcic faience, suggesting that the firing temperature of calcic faience bodies was within the range of 1100–1150?°C. Calcination trials were also performed in order to determine the most probable firing temperatures of the ceramic bodies. Collected data led to the assumption that the raw materials used for the ceramic bodies were kaolinitic clay, quartz sand, limestone, and talc. The raw materials for pó de pedra tiles were found to include kaolinite clay and quartz with firing temperatures estimated within the temperature range of 1150–1360?°C. Technical replicas made on the basis of these investigations were found to have the same mineralogical and capillary properties as the original tiles.
