We conducted a scientific analysis on 13 collections of Dongguk University museum. These were identified to Hard pine ( Pinus spp. )( 4 ) , Salix spp. ( 4 ) , Tilia spp. ( 3 ) , Ginkgo biloba L. ( 2 ) , Acer spp. ( 2 ) , Cryptomeria japonica D. Don ( 2 ) , Alnus spp. ( 1 ) , and Juglans spp. ( 1 ) . In the case of collections requiring fine processing and sculpture, such as Buddhist statues, ceilings, and decorative elements, Tilia spp., Ginkgo biloba L., Hard pine ( Pinus spp. ) , Alnus spp., Acer spp. and Salix spp. were used. Hard pine ( Pinus spp. ) , and Ginkgo biloba L. are conifers, which are easier to process because they have lower strength than species belonging to broadleaved trees. In addition, Tilia spp., Alnus spp., Acer spp. and Salix spp. are broad-leaved trees, but they are uniformly and lightly made of materials with less than 15% shrinkage and less twisting during processing and drying ( Lee, 1997 ) . Therefore, it was confirmed that the artifacts possessed by Dongguk University Museum were selectively used according to the objects to be produced. However, Cryptomeria japonica D. Don were identified in the wooden sarira case and sarira reliquary. Although Cryptomeria japonica D. Don is rough, it is used for furniture and building interior materials ( Lee, 1998 ) . Cryptomeria japonica D. Don is known to be originated in Japan and imported from Japan before 1900 ( Park, 2011 ) . Therefore, it is presumed that wooden sarira case and sarira reliquary are made in Japan or imported from Japan. Through various scientific instruments, it was found that The Wooden Bodhisattva Statue (木彫菩薩立像) and The Wooden Amitabha Samphire Buddhist Statue (木彫阿彌陀三尊佛龕) were remodeled using copper ( Cu ) and gold ( Au ) . Especially, FT-IR analysis showed that abietic acid was detected in the part of The Wooden Amitabha Samphire Buddhist Statue (木彫阿彌陀三尊佛龕) paint. Abietic acid belongs to the rosin component and is currently used as a solvent for varnishes and synthetic resins. Therefore, it is presumed that the past preservation treatment was proceeded by applying varnish or synthetic resin paint, which is a modern material. A collection of pigments, such as Buddha s Disciples Statue (羅漢像) , Buddhist Boy Attendants (童子像) , The Wooden Amitabha Samphire Buddhist Statue (木彫阿彌陀三尊佛龕) , Buddhist Plate (經板) , is presumed that Lead White ( White ) , Cinnabar ( Red ) , Hematite ( Brown ) , Emerald Green ( Green ) , Ultramarine Blue ( Blue ) , which are natural mineral pigments mainly used. Especially, it is confirmed that red pigment of The Buddhist plate (勸修淨業往生捷徑板) was used Cinnabar ( HgS ) , red pigment of Bulgam was used Red Lead ( Pb₃O₄ ) , so it was judged that various pigments were used even if they had the same color depending on the production time, use and form of the artifact. The results of this scientific analysis are expected to be used as basic data for conservation and restoration of museum collections of Dongguk University.
