The manufacturing technique was studied through the structure and material characteristics of the Buddhist Monk Bodhidharma mural painting in Geungnakjeon Hall, Daewonsa Temple. The mural is painted connected to the earthen wall and the Joongkit. The earthen wall consists of an first layer, a middle layer, a finishing layer, and a painting layer. It was come to light that the first layer had a high content of loess below silt, and the finishing layer had a high content of fine sand. The painting layer was colored after preparing a ground layer using a soil mineral pigment. It was come to light that he Buddhist Monk Bodhidharma mural painting was created with the same technique as the Avalokitesvara Bodhisattva mural painting in Geungnakjeon Hall. The murals inside Geungnakjeon Hall belong to a category similar to the Joseon Dynasty’s buddhist mural painting (made of earthen) manufacturing style, but characteristic factors were found in the high fine sand content of the finishing layer, the condition of plastering according to the surface finishing technology, and the painting technique of the Joongkit. It is expected that this information can be used as an important indicator for monitoring the conservation status of murals inside the Geungnakjeon Hall of Daewonsa Temple in the future.
