含氟聚合物用于陕西户县出土新石器彩陶的保护研究 总被引:4,自引:1,他引:3
为对陕西户县大王镇庙底沟遗址出土的新石器时代的彩陶进行保护,在用X射线衍射测得表面风化物的成分及对彩陶含湿量测定的基础上,用不同浓度(30%、20%、10%、5%)四元含氟共聚物(F4-SS)溶液进行加固防护处理,观察加固后彩陶的外观颜色,机械强度、吸水性的变化。结果表明,用F4sS溶液加固处理后,彩陶的机械强度显提高,外观颜色没变化,孔隙水蒸气通道无影响;5%-25%F4-SS用于酥松彩陶加固保护、5%-10%F4-SS用于硬质彩陶的表面防护处理,效果显。说明F4-SS可推广应用于其他彩陶的保护。 相似文献

古陶瓷修复仿釉涂料的研究 总被引:1,自引:0,他引:1
古陶瓷修复是一门综合多种学科的传统技艺,长期以来因缺乏系统的整理和总结,故发展缓慢,在古陶瓷修复中瓷釉工艺直接关系到修补部位的质感和色泽效果,是极为关键的一道工序。传统上采用的仿釉涂料有虫胶漆、醇酸清漆、硝基漆、丙烯酸漆等。为了提高古陶瓷修复质量,在对现有材料测试和筛选的基础上,结合国内外研究的现状,制定出对丙烯酸涂料进行交联的双组分丙烯酸-聚氨酯复合型仿釉涂料的试验路线。通过对引发剂、流平剂、消泡剂、附着力促进剂等多种助剂进行了分门别类的实验研究,确定了树脂合成的最佳配方为:甲基丙烯酸甲酯40%-50%,丙烯酸1%-2%,甲基丙烯酸丁酯10%-20%,丙烯酸丁酯20%-40%,甲基丙烯酸羟乙酯20%-30%,引发剂533M75为1.5%,溶剂为醋酸丁酯。合成工艺为:将醋酸丁酯加热至回流温度为130-140℃,在3小时内滴加单体混合物,滴完后保温1.5小时,冷却,出料得到丙烯酸树脂。固化剂采用HDI三聚体,比例为树脂:固化剂=3:1,搅拌均匀后可直接涂刷。该仿釉涂料经测定,其耐水性、耐溶剂性和耐紫外老化性等指标均优于传统硝基和纯丙烯酸涂料。 相似文献

本文以形制最具代表性的陶鬲为切入点,对罗山天湖商代墓葬出土陶器文化因素构成和墓葬葬俗进行了分析,认为罗山天湖商代墓葬与晚商殷墟类型存在明显差异,而这种差异也正是晚商中心文化势力衰落的一个表现形式。 相似文献

本文通过对宋代瓷器铭文中有关佛教内容的分析,结合佛教在中国流传的历史过程,阐述宋代佛教的世俗化倾向。尽管目前所知的与佛教有关的宋代瓷器铭文资料十分有限,难以全面解答佛教在中国的世俗化问题,但铭文中的内容却无可非议地昭示着佛教进入普通平民的生活后,那种大众化、实用化、民俗化的特征。 相似文献

During fieldwork in 1994, 53 surface collections were made in the archaeologically unknown area of Uganda between Kibiro on Lake Albert and the north bank of the Victoria Nile below the Murchison Falls. Analysis of the collected material revealed a general similarity in the pottery roulettes in use in this area during the past millennium, in spite of some local differences in pot forms and decoration. This suggests the existence of a widespread cultural homogeneity that would have formed part of the background to the growth of the state of Bunyoro. Also found, however, were sherds of Urewe and Chobi ware, as well as of an associated pottery that it is proposed to call “Fajao ware.” These are presumed to belong to the first millennium AD and to suggest the settlement by foodproducers of the lower Victoria Nile, and to a lesser extent the NE margins of Lake Albert, before the appearance there of rouletted pottery. In addition, sites along both the river and the lake produced numerous stone artifacts that indicate the presence of hunter gatherers in the area during the later Pleistocene and early Holocene.
Résumé Au cours de recherches sur le terrain en 1994, on a recueilli en surface 53 pièces dans la région de l’Ouganda archéologiquement inconnue située entre Kibiro sur le lac Albert et al rive nord du Nil Victoria en aval des Murchison Falls. L’analyse des matériaux recueillis a révélé une similarité générale parmi les roulettes à poterie utilisées dans cette région au cours du dernier millénaire, malgré quelques différences locales dans la forme des pots et la décoration. Cela laisse supposer l’existence d’une homogénéité culturelle étendue qui aurait été en partie à l’origine de la croissance de l’état de Bunyoro. En outre, des tessons d’objets Urewe et Chobi ont également été trouvés, ainsi qu’une poterie associée qu ’il a été proposé d’appeler “objet Fajao.” On présume que ces objets appartiennent au premier millénaire après J.- C. et qu ’ils laissent supposer le peuplement de la vallée inférieure du Nil Victoria par des producteurs de nourriture et, dans de moindres proportions, des rives NE du lac Albert, avant l’apparition dans cette région de la poterie décorée à la roulette. De plus, de nombreux objets en pierre ont été découverts sur des sites le long du fleuve et au bord du lac, indiquant la présence dans la région de chasseurscueilleurs à la fin du pléistocène et au début de l’holocène.相似文献

Excavations at Mask Cave on the sacred islet of Pulu off Mabuyag in the central west of Zenadh Kes (Torres Strait) reveal four occupational phases: Phase 1 (2900–3800 years ago), Phase 2 (2100–2600 years ago), Phase 3 (1500–1700 years ago) and Phase 4 (last 1500 years). Faunal remains indicate marine specialization (turtle and fish) during all phases. Petrographic analysis of sherds of finely made red‐slipped pottery dating back 2400–2600 years reveals a unique fabric in terms of current understandings of Oceanic ceramic technologies. Mineral inclusions are consistent with local geology suggesting local manufacture and the existence of Indigenous Australia's first pottery tradition. Pre‐ceramic Phase 1 is associated with demographic expansions across the western islands of Zenadh Kes by local populations of marine‐based hunter‐gatherers who were primarily Aboriginal language speakers. Phase 2 is associated with the immigration of Papuan maritime, horticultural and pottery‐making peoples to the eastern and western islands of Zenadh Kes commencing 2600 years ago. Australian then Papuan settlement expansions across the western islands of Zenadh Kes explain why the local Western‐Central Language has an Aboriginal base with a Papuan overlay. First colonization of the eastern islands by Papuans explains why the local Meriam Mìr language is Papuan. Early red‐slipped pottery in Zenadh Kes is linked to southern coastal Papuan pottery traditions that are reassessed to have a comparable 2600 year antiquity. Papuan settlement of the southern Papuan coast and Zenadh Kes was an extension of the post‐Lapita settlement of the Pacific, an event memorialized in part by Torres Strait Islander oral tradition. 相似文献

A multidimensional approach to functional analysis was employed to examine pottery use, cooking, and subsistence in pre-European North American contexts. A variety of analytic techniques were applied to ceramic assemblages from two sites on the south shore of Lake Superior: the Middle Woodland Naomikong Point site and the Late Woodland Sand Point site. The analyses of both technical attributes and use-alteration traces suggest that a majority of pottery vessels from these sites were used for cooking throughout the Woodland period. Lipid residue analysis corroborates traditional subsistence information but specifies which foods were cooked in pottery vessels. Vessel size varies according to context rather than by time or by function, with larger vessels associated with ritual areas and smaller vessels originating from domestic spheres, a trend potentially related to feasting behavior. Interior carbonization patterns change in frequency between the Middle and Late Woodland periods, suggesting a shift in cooking and possibly subsistence practices. 相似文献

This article presents the results of petrographic analyses of a collection of sixty potsherds from various sites of the Iron Age period in south‐eastern Arabia. Several macroscopic groups were identified during previous research. The fine red painted ware and the sandy buff ware appear to be homogeneous in composition and might represent two groups of production. Compositionally, fine red painted ware recalls Bronze Age pottery groups in Oman. Sandy buff ware could have been produced in the oasis of Al Ain, in the Emirate of Abu Dhabi. Both groups are represented at several sites, which indicates regional exchange. One sherd from Rumeilah could be related to Mesopotamian ceramics and is probably a Mesopotamian import. 相似文献
