Industry Observation: In recent years, with the increasing public awareness of cultural heritage protection, the conservation and restoration of ancient jade artifacts have received growing attention. This not only concerns the continuation of historical lineage but also has a profound impact on the sustainable development of the jade cultural industry. As the birthplace of jade culture, China possesses tens of thousands of ancient jade treasures, and their current protection status and future development path have become a focal point for both inside and outside the industry.
According to the latest data released by the National Cultural Heritage Administration, as of the end of 2023, the number of ancient jade artifacts in national collections has exceeded 1.5 million, with precious cultural relics above Level 3 accounting for 12.5%. However, due to the special nature of the material, its ancient age, and complex preservation environments, the problem of ancient jade deterioration remains severe. Professor Wang Yamin, Chairman of the China Association for Cultural Heritage Conservation Technology and former Vice President of the Palace Museum, pointed out at a recent industry seminar: “The microscopic structure of ancient jade is complex and easily affected by temperature, humidity, light, and microbial erosion. Traditional restoration methods can no longer meet the growing demand for protection.”
In terms of technological empowerment, non-destructive testing technology is becoming a 'sharp tool' for ancient jade protection. For example, the 'Multi-spectral Imaging and 3D Laser Scanning Integrated System' jointly developed by the Shanghai Museum and Fudan University has been successfully applied to the diagnosis of deterioration and morphological restoration of over 200 ancient jade artifacts from the Warring States period to the Han Dynasty. This system can acquire high-precision texture, cracks, and infiltration information without direct contact with the artifact, providing a scientific basis for subsequent restoration plans. According to Professor Li, project leader at Fudan University's Center for Cultural Heritage Conservation Technology, this technology can improve the identification rate of ancient jade deterioration by more than 30% and significantly shorten the diagnosis cycle.
Furthermore, the concept of preventive conservation has gradually gained traction. The 'Intelligent Environmental Monitoring and Control System for Ancient Jade,' jointly developed by the Zhejiang Provincial Institute of Cultural Relics and Archaeology and Hangzhou Normal University, has been put into trial operation at the Liangzhu Museum. This system deploys miniature sensors to monitor real-time key indicators such as temperature, humidity, PM2.5, and volatile organic compounds inside and outside the display cases, and provides early warnings of potential risks through big data analysis. According to Mr. Jiang Weidong, Director of the Liangzhu Museum, since the system's operation, the micro-environmental fluctuations of ancient jade in the exhibition hall have been reduced by 40%, effectively slowing down the aging rate of the artifacts.
However, technological progress is not a panacea. The restoration of ancient jade still highly depends on experienced professional talents. Currently, there are fewer than 100 experts nationwide with advanced ancient jade restoration qualifications, indicating a huge talent gap. Professor Zhang from Peking University's School of Archaeology and Museology emphasized: “Technology is a means, but talent is the core. We urgently need to establish a comprehensive talent training system that combines traditional craftsmanship with modern technology to cultivate more interdisciplinary talents who understand both history and culture, and are proficient in scientific restoration.”
In terms of cultural inheritance, digital display and public education are playing increasingly important roles. The Nanjing Museum's 'Cloud Ancient Jade Exhibition,' utilizing VR/AR technology, allows visitors to admire ancient jade details from a 360-degree close-up perspective and learn about the historical stories behind them. Within just six months of its launch, the exhibition has attracted over 5 million visits. This immersive experience has greatly stimulated public interest in ancient jade culture.
Looking ahead, the protection of ancient jade artifacts will be a systematic project involving interdisciplinary collaboration and multi-stakeholder participation. The government should increase funding, encourage deep cooperation between research institutions and museums; industry associations should act as bridges, promoting the formulation of technical standards and talent exchange; and the public should actively participate in jointly safeguarding this precious cultural heritage. As Mr. Lü Zhangshen, President of the China Cultural Relics Society and former Director of the National Museum, stated: “Ancient jade is not just a material remnant, but also the carrier of the Chinese national spirit. Protecting ancient jade is protecting our roots and soul.”
