Industry Observation: Digital Empowerment, Ancient Jade Rebirth: Technology Safeguards Chinese Treasures
In recent years, with the increasing public awareness of cultural heritage protection and the rapid development of technological advancements, the field of ancient jade cultural relic protection is undergoing a profound transformation. From traditional physical restoration to cutting-edge digital modeling, the introduction of technological means has not only improved the efficiency and precision of cultural relic protection but also opened up new avenues for the inheritance and research of ancient jade.
Data-Driven New Paradigm for Protection
China is one of the earliest countries in the world to use and carve jade, leaving behind countless exquisite ancient jade artifacts over thousands of years of history. However, these precious cultural heritages have suffered erosion and damage over the long years, and their protection has always faced enormous challenges. According to the 'National Cultural Relics Survey Report' released by the National Cultural Heritage Administration in 2023, there are currently approximately 1.2 million pieces of ancient jade in Chinese museums, nearly 20% of which suffer from various degrees of damage, urgently requiring specialized protection and restoration. Against this backdrop, digital technology is becoming the 'new engine' for ancient jade protection.
Taking the Palace Museum as an example, it has collaborated with research institutions such as Tsinghua University and Peking University to launch the 'Establishment of Ancient Jade Digital Archives and Disease Analysis' project. This project utilizes high-precision 3D laser scanning technology, CT scanning, and multispectral imaging technology to conduct comprehensive data collection on nearly 5,000 important ancient jade artifacts in its collection. According to Dr. Li Ming, a researcher at the Department of Cultural Heritage Conservation Science at the Palace Museum and the project leader: 'Through digital modeling, we can not only achieve high-precision replication and virtual display of ancient jade artifacts but also non-destructively obtain critical information such as their internal structure, material composition, and disease distribution, providing data support for developing scientific restoration plans. For instance, we once discovered micro-cracks inside a dragon-shaped jade pendant from the Warring States period through CT scanning, which would be easily overlooked by traditional visual inspection. However, digital technology made them visible, thus avoiding potential secondary damage during the restoration process.'
Technology Empowers Restoration and Exhibition
In addition to data collection, technology also plays an irreplaceable role in ancient jade restoration and exhibition. For example, at the Shaanxi Provincial Institute of Archaeology, a team led by young cultural relic restorer Wang Fang is attempting to apply 3D printing technology to the repair and matching of ancient jade fragments. They achieve this by 3D scanning the incomplete jade artifacts and then, combining texture data from homologous jade materials, 3D printing highly matching repair parts using polymer materials. Wang Fang stated: 'This technology not only effectively addresses the challenge of low material matching in traditional restoration but also enables reversible restoration without altering the original artifact, maximizing respect for the artifact's historical information. Currently, we have successfully restored over 10 pieces of Han Dynasty jade bi and Tang Dynasty jade belt plaques.'
In terms of exhibition, virtual reality (VR) and augmented reality (AR) technologies provide the public with immersive ancient jade appreciation experiences. The 'Cloud Jade Museum' project launched by the Shanghai Museum in collaboration with Tencent allows users to enjoy 360-degree close-up views of rarely seen treasures, such as the Liangzhu Culture jade cong king and the Han Dynasty jade burial suit sewn with gold thread, through VR technology. According to the project team's statistics, since its launch, the platform has attracted over 3 million visits, greatly expanding the reach of ancient jade culture.
Challenges and Prospects
Despite the breakthroughs brought by technology to ancient jade protection, challenges still exist. High equipment investment, a shortage of professional talents, and data security issues are the main bottlenecks currently facing the industry. Zhang Hua, Director of the Cultural Relics Department of the Ministry of Culture and Tourism, pointed out at a recent industry forum: 'We need to increase investment in scientific research and development for cultural relic protection, cultivate more interdisciplinary composite talents, and establish a sound data management and sharing mechanism to ensure the security and rational use of digital cultural relics.'
Looking ahead, with the further maturity of cutting-edge technologies such as artificial intelligence, big data, and blockchain, ancient jade cultural relic protection will enter a new stage of greater intelligence and refinement. For example, AI-based image recognition technology is expected to achieve early warning and automatic diagnosis of ancient jade diseases; blockchain technology may provide more reliable solutions for ancient jade traceability and anti-counterfeiting. It is foreseeable that with the continuous empowerment of technology, the millennial brilliance of Chinese ancient jade will be presented to the world more completely and vividly, radiating new vitality.
