Material analysis of the Liao Dynasty Eleven-faced Avalokitesvara statue in Guanyin Pavilion of Dule Temple
The Statue of Eleven-faced Avalokitesvara in Guanyin Pavilion of Dule Temple has been preserved to the present day,but there are some diseases such as cracking,hollowing and falling off.The materials for the statue core were investigated using ultra depth-of-field 3 D microscopy,X-ray diffraction and laser particle size distribution analysis.The contractility of clay samples was analyzed by controlling the contents of sand and fiber,and the effect of fiber content on the contractility of clay was explored.The results show that the raw materials for the statue core were taken from the local area,and the size of clay particles was mostly between 5 μm and 70 μm(accounting for about 79.5％of the total).The main mineral components were quartz and illite,with some albite and potassium feldspar and a small amount of kaolinite existing.For the coarse mud layer,the sand content was about 35％,the wheatgrass(a mixture of wheat straw and husk)content was about 6％-9％,and the length was mostly below 2 cm.For the fine mud layer,the sand content was about 30％,the hemp content was about 2.1％,and the length was mostly concentrated at 2 cm.The addition of wheat straw and hemp could inhibit the contraction of mud.With the increase of wheat grass content,the inhibitory effect increased first and then decreased,with the addition of 6％wheat grass boasting the best inhibitory effect.The final shrinkage rate of the sample could be significantly reduced by adding hemp,but the amount of hemp had little effect on the reduction rate.The fiber ratio of the statue core had a good effect of inhibiting contraction.In this study,material composition information of the core of the Eleven-faced Avalokitesvara statue was obtained,and as was the influence of fiber ratio on the contraction of the statue core.This work provides a reference for the restoration and conservation of the statue.
