【摘要】：金元时期在豫西中部地区多个窑址同时生产青瓷和钧瓷,发掘于2005年的汝州东沟窑遗址即是该类窑址典型代表之一。为系统了解东沟窑青瓷和钧瓷的胎釉元素组成特征和工艺特点、揭示两类瓷器各自随时代变化的规律,本项研究采用EDXRF和OM对东沟窑遗址出土且地层明确的43件金、元时期青瓷与钧瓷标本胎、釉化学组成和工艺性能进行测试分析,探讨了胎、釉的原料配比、釉层厚度和胎釉反应层厚度等工艺特征随时代和标本类型的变化规律。研究结果表明:东沟窑同时期青瓷和钧瓷胎体元素组成较接近,而两者釉的元素组成差异明显,金元钧瓷釉的SiO2/Al2O3摩尔比值都明显高于同时代青瓷的相应比值,呈现钧瓷釉典型的高硅低铝组成特征。从金代到元代,东沟窑青瓷和钧瓷釉都呈现从钙釉向钙-碱釉的转变。本项研究还观察到金元钧瓷的釉层和反应层厚度均高于同时代的青瓷;而从金过渡到元,两类瓷片的釉层和反应层厚度均趋厚。本项研究对揭示金元时期豫西中部地区青瓷和钧瓷间的传承和演化关系提供了有意义的科技数据。
[Abstract]:Both celadon and Jun porcelain were produced simultaneously in many kiln sites in the central part of Henan during the Jin and Yuan dynasties. The Donggou kiln site of Ruzhou in 2005 was one of the typical representatives of this kind of kiln site. In order to systematically understand the composition and technological characteristics of the glaze elements of the celadon and Jun porcelain of Donggou Kiln, and to reveal the changing laws of the two kinds of porcelain with the times, this study used EDXRF and OM to study 43 gold pieces unearthed from Donggou Kiln site with definite stratum. The chemical composition and technological properties of celadon and Jun porcelain samples in Yuan Dynasty were tested and analyzed. The changes of the technological characteristics such as the ratio of the material, the thickness of glaze layer and the thickness of reaction layer of glaze were discussed with the age and the type of specimen. The results showed that the composition of the elements of celadon and Jun porcelain in Donggou kiln at the same period was close, but the element composition of the two glazes was obviously different. The molar ratio of Sio _ 2 / Al _ 2O _ 3 of Jin Yuan Jun glaze was obviously higher than that of contemporary celadon. Jun porcelain glaze is typical of high silicon and low aluminum composition. From Jin Dynasty to Yuan Dynasty, Donggou kiln celadon glaze and Jun porcelain glaze have changed from calcium glaze to calcium alkali glaze. The thickness of glaze layer and reactive layer of Jinyuan Jun porcelain is higher than that of contemporary celadon and the thickness of glaze and reactive layer of the two kinds of porcelain is thicker than that of contemporary celadon. This study provides meaningful scientific and technological data for revealing the relationship between celadon and Jun porcelain in the central part of western Henan during the Jin and Yuan dynasties.
