长沙窑位于中国南部湖南省长沙市，以唐代（公元7 -10世纪）出口的彩瓷而闻名。虽然学界普遍认为铜红瓷起源于长沙窑，但对其釉质化学特性和显色机理的研究还不充分。为此，采用能量色散x射线荧光（EDXRF）、同步加速器x射线吸收近边光谱（XANES）、微x射线衍射（mux - xrd）、显微镜和扫描电子显微镜（SEM）等方法对长沙窑出土的一件红色不透明釉瓷碎片进行了分析。结合XANES和mu-XRD结果表明，金属铜是红色色调的主要显色元素状态。另一方面，该研究首次证明了长沙窑样品的釉是一种典型的相分离结晶釉，其针状晶体周围有大颗粒，导致釉面不透明。由于长沙窑样品为中国古代早期铜红瓷遗物，有助于了解中国铜红瓷的起源，丰富中国古代陶瓷文化的知识。(C) 2016 Elsevier Ltd and Techna Group S.r.l版权所有
Changsha Kiln, located at Changsha in Hunan Province, south of China, is famous for exported and coloured porcelain during the Tang Dynasty (A.D. 7th-10th century) period. Although the opinion that copper-red porcelain originates from Changsha Kiln is widely accepted in academic circles, chemical characters of glaze and colour mechanism of its copper-red porcelain have not been fully investigated and studied. Therefore, a shard of opaque glaze porcelain with red pigments which excavated at Changsha Kiln (A.D. 7th-10th century) was analyzed by Energy dispersive X-ray fluorescence (EDXRF), Synchrotron X-ray absorption near-edge spectroscopy (XANES), micro X-ray diffraction (mu-XRD), microscopy and scanning electron microscopy (SEM) methods. Combining with XANES and mu-XRD results, it indicates that metal copper is the major colouring-generation element status of the red hue. On the other hand, for the first time the study demonstrates that glaze of the sample from Changsha kiln is a typical phase separated-crystalline glaze with large particles surrounding acicular crystals which lead the opaque appearances. Because the sample from Changsha Kiln is Chinese ancient early stage copper-red porcelain relic, it will help to understand the origin of copper-red porcelain in China and enrich the knowledge of Chinese ancient ceramic culture.
