通过对陕西地区馆藏和出土北朝至唐代金铜佛像的调查和研究,结合铸造复原实验,发现唐代范铸小型金铜佛像的四足方座基是通过类似贴泥条等方法进行机械造型,留出外范与内芯之间的空腔而铸造出的。这种方法与中国商周至汉代青铜器范铸工艺是一致的,四足方座基的铸造是中国古代范铸工艺思想的延续,是佛教中国化进程中的重要一步。 Through the investigation and study of the bronze Buddha statues collected and unearthed from the Northern Dynasties to the Tang Dynasty in Shaanxi Province and the founding restoration experiments, it was found that the four-foot square statues of the small cast bronze statues in the Fan dynasty in Tang Dynasty were mechanically shaped by methods similar to plaster, The cavity between the outer and inner cores is cast. This method is consistent with the bronze casting process from the Shang and Zhou dynasties in China to the Han Dynasty. The casting of quadruped squares is a continuation of the ancient Chinese casting and casting process and is an important step in the process of Chineseization of Buddhism.
