Core Viewpoint - The excavation of two Tang Dynasty dragon heads in Xiong'an, Hebei, represents a significant archaeological find, as such artifacts are extremely rare and provide insights into ancient Chinese craftsmanship and cultural heritage [4][5]. Group 1: Archaeological Discovery - Two Tang Dynasty dragon heads, referred to as No. 9 and No. 10, were unearthed from the ancient city site in Xiong'an, marking a rare find as few such artifacts exist in China [4]. - The dragon heads are made of pottery and are relatively well-preserved compared to other finds from regions like Heilongjiang, Shandong, and Henan [4]. Group 2: Research and Restoration Process - The dragon heads were sent to the Key Laboratory of Archaeological Science and Cultural Heritage Protection at the Chinese Academy of Social Sciences for restoration and research [4]. - Initial cleaning and data collection involved multi-angle 3D imaging to document the condition and location of the fragments, followed by extraction, cleaning, desalting, and drying processes [4][5]. Group 3: Material Analysis - Testing revealed that the firing temperature of the dragon heads was approximately 686 degrees Celsius, with various pigments identified, including manganese for black, vermilion for red, copper for green, and lead for white [5]. - The analysis also uncovered the presence of straw and pottery fragments within the body of the dragon heads, as well as fingerprints of the potter on the No. 10 dragon head [5]. Group 4: Virtual Reconstruction - A collaborative effort with Beijing Institute of Technology utilized 3D laser scanning for data collection, leading to virtual reconstruction of the dragon head fragments [6]. - The restoration team, including students from various universities, successfully pieced together the fragments, although some parts remained missing, which were later filled with plaster [6]. Group 5: Cultural Significance - The successful restoration of the dragon heads adds a new category to the representation of ancient Chinese dragon imagery and provides valuable materials for studying Tang Dynasty architectural components [6]. - This find also reinforces the historical continuity of the Xiong'an New Area, contributing to the understanding of its millennia-old cultural heritage [6].
