Industry Observation
In recent years, with the increasing public awareness of cultural heritage protection and the rapid development of technology, the field of ancient jade artifact protection is undergoing a profound transformation. From traditional physical restoration to the establishment of digital archives, and further to the construction of preventive protection systems, the concept of 'Digital Jade' has not only injected new vitality into the perpetual inheritance of ancient jade but also brought new insights and opportunities to the entire jade industry.
Policy-Driven and Technology Integration: A New Normal for Protection
As the birthplace of ancient jade culture, China boasts millions of precious jade artifacts. According to the latest statistics from the National Cultural Heritage Administration, as of the end of 2023, the national collection of jade artifacts has reached over 1.2 million pieces, with more than 30% being precious cultural relics above the third grade. However, for a long time, the protection of ancient jade has faced multiple challenges, including fragile materials, complex preservation environments, and rampant illegal excavation and smuggling.
To address these challenges, the national government has introduced a series of policies. In 2022, the 'Guiding Opinions on Strengthening Scientific and Technological Innovation in Cultural Relics' jointly issued by the Ministry of Culture and Tourism and the National Cultural Heritage Administration explicitly stated the need to “intensify research and application of digital protection and restoration technologies for cultural relics,” especially promoting the “deep integration of high-precision 3D modeling, multispectral imaging, non-destructive testing, and other technologies in cultural relic protection.”
Taking the Palace Museum as an example, it has been at the forefront of digital protection for ancient jade. According to Dr. Wang Zhijie, Director of the Department of Conservation Science at the Palace Museum, over the past five years, the Palace Museum has completed high-precision 3D scanning and multispectral imaging of approximately 15,000 ancient jade pieces, establishing detailed digital archives. These digital archives not only contain information about the jade's material, craftsmanship, and diseases but also enable immersive public experiences of ancient jade through virtual reality (VR) and augmented reality (AR) technologies. Dr. Wang stated, “The establishment of digital archives is the first step towards achieving the 'eternal life' of ancient jade, effectively avoiding irreversible losses caused by natural deterioration and human damage.”
'Digital Jade': From Concept to Practice
'Digital Jade' is not merely a digital replica of a jade artifact; it is a comprehensive platform integrating data acquisition, analysis, storage, display, and dissemination. Taking the 'Liangzhu Jade Digital Twin Project' collaborated by the Zhejiang Provincial Museum and Hangzhou Dianzi University as an example, this project utilizes technologies such as LiDAR scanning, X-ray fluorescence spectroscopy (XRF), and Raman spectroscopy to conduct comprehensive data collection on the microstructure, chemical composition, and carving marks of dozens of representative jade artifacts unearthed from the Liangzhu culture. Li Ming, professor at the School of Computer Science, Hangzhou Dianzi University, and project leader, stated that through this data, researchers can not only gain a deeper understanding of the jade crafting techniques of Liangzhu ancestors but also provide scientific basis for jade traceability and authenticity identification.
Furthermore, preventive protection has become a crucial component of 'Digital Jade'. By embedding micro-environment monitoring sensors in museum display cases to real-time monitor parameters such as temperature, humidity, light, and air pollutants, combined with big data analysis, potential risks can be pre-warned, and preservation environments can be adjusted promptly, thereby maximizing the lifespan of ancient jade. According to data from the Shanghai Museum's Cultural Relics Conservation Center, since the introduction of the intelligent micro-environment monitoring system in 2021, the fluctuation range of the micro-environment for ancient jade in the collection has decreased by nearly 40%, effectively slowing down the weathering and deterioration of the jade' surface.
Industry Opportunities and Challenges
The rise of 'Digital Jade' brings numerous opportunities to the jade industry. Firstly, it has spawned new service formats, such as cultural relic digitization services, virtual exhibition development, and digital cultural and creative product design. Secondly, high-precision data also provides strong technical support for jade identification, traceability, and market standardization. In the future, consumers are expected to track the 'digital identity' of jade through blockchain technology, thereby enhancing purchasing confidence.
However, challenges also coexist. High equipment investment, scarcity of professional talent, data security, and intellectual property protection issues still need to be addressed by the industry as a whole. Zhang Hua, Vice President of the Jade Research Committee of the Chinese Society of Cultural Relics, believes: “To promote the healthy development of 'Digital Jade,' multi-party cooperation among governments, research institutions, museums, and enterprises is needed to establish unified data standards and sharing mechanisms, and to strengthen the cultivation of interdisciplinary talents.”
Looking ahead, with the continuous iteration of new technologies such as 5G, artificial intelligence, and blockchain, 'Digital Jade' is expected to build a more open, intelligent, and secure ecosystem for ancient jade protection and utilization. This will not only be a milestone in the inheritance of excellent Chinese traditional culture but also set a new paradigm for global cultural heritage protection.
