1981 Scientific Restoration of Jian Kiln Rabbit-Hair Glaze
In the late 1970s and early 1980s, Chinese researchers began a scientific effort to restore the lost techniques of Song-dynasty Jian kiln (建窑) ceramics.
The following information is based on an official Technical Appraisal Certificate (技术鉴定证书) issued in May 1981 in Jianyang, Fujian Province.
The project focused on recreating the famous Rabbit-Hair glaze (兔毫釉) tea bowls of the Song Dynasty, one of the most celebrated ceramic traditions in Chinese history.
Project Organizations
Project Lead:
Fujian Provincial Light Industry Research Institute (福建省轻工业研究所)
Collaborating Institution:
Jianyang County Porcelain Factory (建阳县瓷厂)
Supervising Authority:
Fujian Provincial Science Commission (福建省科学技术委员会)
Appraisal Date:
May 10, 1981 – Jianyang, Fujian
Background
Jian kiln (建窑) was one of the most famous kilns of the Southern Song Dynasty. Located in present-day Jianyang, Fujian Province, it was known primarily for producing tea bowls with distinctive iron-rich glazes such as Rabbit Hair (兔毫), Oil Spot (油滴), and other crystalline patterns.
These bowls were prized during the Song Dynasty for use in whisked tea ceremonies and were considered luxury items. However, production eventually disappeared, and the original techniques were largely lost.
Beginning in October 1979, researchers began a program to experimentally recreate Song-dynasty Jian ware using archaeological evidence, historical records, and scientific analysis.
Research Process
During the restoration project, researchers conducted numerous experimental firings and glaze tests.
More than 200 experimental ceramic pieces were produced in an attempt to reproduce the appearance and structure of traditional Jian ware.
The project specifically focused on reproducing the classic Rabbit-Hair glaze (兔毫釉).
Technical Findings
After extensive testing, the research team concluded that the essential techniques required to reproduce rabbit-hair glaze had been successfully mastered.
The clay body formulas, glaze compositions, and firing processes were found to be viable, and experimental bowls were successfully fired in a traditional dragon kiln (龙窑).
Researchers concluded that the recreated ceramics achieved three important forms of similarity to historical Jian ware:
- 形似 – similarity in form and shape
- 质似 – similarity in material and structure
- 神似 – similarity in artistic spirit and character
Scientific Analysis
Additional scientific testing was conducted by the Shanghai Institute of Ceramics, Chinese Academy of Sciences (中国科学院上海硅酸盐研究所).
Researchers used modern scientific methods including:
- Optical microscopy
- Electron microscopy
- Chemical composition analysis
The results showed that the microstructure of the recreated ceramics closely matched the structure of Song-dynasty Jian kiln wares.
Conclusion of the Appraisal Committee
The appraisal committee concluded that the restoration project was successful and recommended continued research and expanded production of Jian kiln ceramics.
This research marked an important milestone in the modern revival of Jian ware, helping reintroduce traditional glaze techniques that had been lost for centuries.
Expert Review Committee
The appraisal meeting included experts from numerous Chinese cultural and scientific institutions, including:
- Central Academy of Arts and Crafts
- Zhejiang Academy of Fine Arts
- Shanghai Museum
- Chinese Academy of Sciences
- Fujian Museum
- Jingdezhen Ceramic Institute
- Fujian Cultural Relics Bureau
- Dehua Porcelain Factory
Historical Significance
The 1981 restoration project represents one of the earliest documented scientific efforts to revive Jian kiln ceramics in modern China.
Many of today’s Jian Zhan artists and kilns trace their technological foundations back to the research carried out during this period.
