上林湖后司岙窑址秘色瓷的釉色特征及呈色影响因素研究

The Feature and Coloration Factors of The Mi'se Celadon Excavated at Shanglinhu Housi'ao Kiln Site

为揭示秘色瓷和普通越窑青瓷釉色特征和发展规律,探讨釉色的影响因素,本文利用分光光度计、光学与电子显微镜、X射线荧光能谱仪(EDXRF)等,对后司岙窑址秘色瓷及普通越窑青瓷、荷花芯窑址普通越窑青瓷进行了分析研究。结果表明:(1)与普通越窑青瓷相比,后司岙秘色瓷釉色更偏青、饱和度更低,其釉色处于普通越窑青瓷向汝窑青瓷、南宋官窑青瓷等釉色的审美过渡阶段。(2)后司岙窑址秘色瓷和普通越窑青瓷釉层较为相似,均属于较薄的透明釉,影响二者釉层颜色差异的因素主要为胎体颜色及釉层中的过渡金属离子。(3)后司岙秘色瓷胎体颜色较白且深色颗粒较少,使得秘色瓷釉面明度值较高且更加纯净透亮。(4)后司岙秘色瓷采用的瓷质匣钵和釉封的工艺是其釉中Fe2+含量高于普通越窑青瓷的原因之一,后司岙秘色瓷釉色因而更加偏青。

As the result of the test of the shard samples of the Mi'se celadon and the common Yue ware respectively excavated at the sites of Housi'ao kiln and Hehuaxin kiln for their color characteristics, development and coloration factors by Spectrophotometer, Optical Microscope, Electron Microscope and EDXRF together, it shows as follows: Firstly, the common Yue ware is less greenish hue but higher saturation than the Housi'ao Mi'se celadon whose glaze color is in the aesthetic transition from the Yue green object to the Ru celadon and the Southern-Song official celadon wares. Secondly, the glaze layers of both the Mi'se celadon of Housi'ao kiln and the common Yue green ware are thin and transparent, but they look different due to the different body color of themselves and the content and valence state of transition metal ion in the layers of glaze. Thirdly, the Mi'se celadon looks bright, pure and transparent owing to its white and clear body with fewer dark particles. Fourth, the Mi'se celadon of Housi'ao kiln is much green-glazed with more Fe^(2+) than the common Yue green ware partly because the former is fired technically inside the porcelain saggar and sealed with glaze.
