摘要/Abstract

摘要： 吉州窑作为宋代南方八大民窑之一,因绚丽的釉色而闻名于世。本文采用景德镇地区的传统陶瓷原料,以CuO为着色剂成功实现了吉州窑绿釉的无铅化制备,研究了CuO含量对铜釉色彩特性的影响。结果表明:随着CuO含量的增加,釉层粘度逐渐降低,釉面依次呈现淡青色、青绿色、绿色、墨绿色、蓝色。Cu²⁺的呈色主要以绿色为主,但高浓度的Cu²⁺作为玻璃改性剂破坏了SiO₂网络,增加了非桥氧的数量和Cu²⁺周围氧离子的密度,此时Cu²⁺的呈色主要为蓝色。掺入CuO后,样品均存在圆形和蠕虫状两种相分离结构。当CuO含量较高时,圆形相分离结构尺寸较小满足瑞利散射,产生蓝色乳光,加深釉面呈色;当CuO含量较低时,圆形相分离结构尺寸较大满足米氏散射,产生白色乳光。吉州窑无铅绿釉的呈色机制是铜离子价态和相分离结构协同耦合作用的结果。

Abstract: Jizhou kiln, one of the eight southern folk kilns of the Song Dynasty, is famous for its brilliant glaze colors. The traditional ceramic raw materials in Jingdezhen area were used to successfully realize the lead-free preparation of green glaze from Jizhou kiln with CuO as colorant, and the effect of CuO content on the color characteristics of copper glaze was also investigated. The results indicate that with the increase of CuO content, the viscosity of glaze layer gradually decreases, and the glaze surface shows light blue, green, dark green, and blue colors in sequence. Cu²⁺ is mainly green color, but the high concentration of Cu²⁺ as a glass modifier destroys the SiO₂ network, increasing the amount of non-bridging oxygen and the density of oxygen ions around Cu²⁺, and the color of Cu²⁺ is mainly blue. After the addition of CuO, the samples exhibite circular and worm-like phase-separated structure. When the CuO content is higher, the smaller size of circular phase separation structure meets Rayleigh scattering, producing blue opalescence and deepening the glaze color. When the CuO content is lower, the larger size of circular phase separation structure satisfies Mie scattering and produces white milky light. The coloration mechanism of lead-free green glaze from Jizhou kiln results from the synergistic coupling effect of copper ion valence state and phase-separated structure.

Key words: Jizhou kiln, lead-free green glaze, CuO, phase-separated structure, ion coordination, coloration mechanism
