景德镇御窑遗址出土青花绣墩的考古修复新方法研究

景德镇御窑遗址出土的15世纪中叶青花方胜纹绣墩,体量较大,器形特殊,出土时破损和缺失严重,修复难度较大。本研究通过分析传统考古修复中石膏作为补配材料的局限性,利用3D扫描打印的优势,设计采用新颖的高强度透明树脂取代传统修复补缺材料,并且结合特制的加固装置完成对大型青花绣墩的考古修复,满足了后期研究与展览的需要。本研究提出了具有一定实践意义的3D打印补配大件异形陶瓷器的修复技术路线。

Research on an innovative method of archaeological restoration of a blue and white Xiu stool unearthed from the Yuyao site in Jingdezhen

The blue and white Xiu stool unearthed from the Yuyao site in Jingdezhen dates from the mid-fifteenth century and is large in size and special in shape. When unearthed, it was seriously damaged and had significant numbers of missing pieces, making restoration highly difficult. By analyzing the limitations of gypsum as a supplemental material in conventional archaeological restoration, the conservators took advantage of 3D scanning and printing, pioneered the adoption of transparent resins with high-hardness to replace conventional restoration materials, and completed the archaeological restoration of the large blue and white Xiu stool, along with a customized reinforcement device, meeting the needs of subsequent research and exhibition. In this paper, the conservators put forward a practical method involving 3D printing technology for restoring ceramics that are large and irregular in shape.
