On The Construction History and Craftsmanship of the Polychrome Patterns on the Inner Eaves of the Rear Hall of Fengxian Dian in the Forbidden City
Fengxian Dian,the imperial hall for ancestry worship,has the Xuanzi-styled polychrome patterns with the feature of the late Ming-early Qing times on the inner eaves of the rear hall.The traces left indicate the patterns were repainted a couple of times as is recorded in the files of the Qing Court.Taking the sampled objects from four parts of the structure,this thesis reviews the history and crafts of the Xuanzi-styled polychrome pattern construction and restoration,especially to localize the detailed areas repaired through the periods of Shunzhi,Kangxi,Qianlong and Daoguang using the instruments such as cross-section microscopy,polarized light,SEM-EDS and the related research results together.Moreover,the test analysis on the kinds of the materials and the technique characteristics suggests that the craft of'Tanhuo'(摊活)using light-colored pigments already worked in the Xuanzi-styled painted patterns of the first 20 years of Emperor Kangxi(康熙)period.Third,it is indicated by the test results and the files that the gold content of gold foil in the polychrome paintings of Fengxian Dian in Emperor Daoguang(道光)period is lower than ever before,which reflects that the cost of production was deliberately controlled by the Jiangsu traders of gold foil of that time.
