Industry Observation: In recent years, with the increasing awareness of cultural heritage protection and the rapid development of digital technology, the protection and research of ancient jade artifacts are ushering in unprecedented opportunities. In 2023, the National Cultural Heritage Administration, in conjunction with multiple departments, issued the "Guiding Opinions on Strengthening Cultural Heritage Scientific and Technological Innovation," explicitly proposing to deeply apply digital technology to all aspects of cultural relic restoration, monitoring, and display, providing new protection solutions for ancient jade, a vital carrier of Chinese civilization.
Ancient jade, as a unique symbol of Chinese civilization, possesses irreplaceable historical, artistic, and scientific value. However, its material fragility, the complexity of its burial environment, and the erosion of time all pose significant challenges to protection efforts. Traditional protection methods, such as physical reinforcement and chemical cleaning, have, to some extent, slowed down the deterioration of artifacts but often struggle to achieve complete information extraction and multi-dimensional display. It is against this backdrop that digital technology has begun to play an increasingly important role.
Taking the "China Ancient Jade Protection and Research Center" located in Luoyang as an example, since the launch of its "Heluo Digital Jade Soul" project in 2022, the center has successfully conducted high-precision 3D scanning and data modeling on over 3,000 unearthed ancient jade pieces. According to Professor Li Ming, director of the center, the "multi-spectral imaging technology" employed by the project can penetrate the surface alterations and patinas of jade, revealing its internal structure and early carving marks, providing crucial evidence for dating and provenance. For instance, during the digital analysis of a Shang Dynasty jade ge (dagger-axe) unearthed from Yinxu in Anyang, researchers used X-ray fluorescence spectrometry (XRF) to precisely analyze its trace element composition and compared it with databases of Xinjiang Hetian jade and Liaoning Xiuyan jade. This allowed them to preliminarily infer the source of the jade material, offering new clues for the study of Shang Dynasty jade trade routes.
Beyond information acquisition, digital restoration has also made groundbreaking progress. The "Jade Micro-crack Non-destructive Restoration Evaluation System," jointly developed by the Nanjing Museum and Southeast University, utilizes AI algorithms for intelligent identification and simulated restoration of ancient jade micro-cracks, predicting the effects of different restoration schemes. In 2023, this system was successfully applied to the restoration of a Warring States period dragon-shaped jade pendant, effectively avoiding potential secondary damage from traditional restoration methods and shortening the restoration cycle by approximately 20%. According to Dr. Wang Fang, the project leader, "3D printing technology" will be introduced in the future for virtual infilling of missing parts, achieving the highest standard of "reversible restoration."
Digital technology also demonstrates immense potential in public education and cultural dissemination of ancient jade. The Palace Museum's "Digital Forbidden City · Jade Gallery" online platform utilizes VR/AR technology, allowing visitors to immerse themselves in a 360-degree appreciation of the museum's jade collection and even "touch" the intricate details of the jade texture. By the end of 2023, the platform had attracted over 120 million visits, with overseas users accounting for 15%, significantly enhancing the international influence of ancient Chinese jade.
However, challenges persist. The high cost of acquiring and maintaining high-precision equipment, a significant shortage of professional technical talent, and issues such as data security and intellectual property protection are all real difficulties currently faced by the digital protection of ancient jade. Furthermore, digital technology is merely an auxiliary tool; its ultimate goal remains to better understand and protect physical artifacts, rather than completely replacing traditional research. Finding a balance between technological progress and humanistic care is a subject the industry needs to continuously contemplate.
Looking ahead, with the deep integration of technologies such as 5G, big data, and artificial intelligence, the digital protection of ancient jade will move towards a more intelligent and collaborative stage. We have reason to believe that, empowered by technology, these ancient jade treasures, carrying the profound historical memory of the Chinese nation, will continue to tell their millennium-old stories in safer and more vivid ways.
