In March,2008,the tomb of Fu Bi,a famous Northern Song dynasty prime minister,was discovered at a construction site in the northern suburb of Luoyang.Rare wall paintings with images of door guards and a Black Tortoise were found.To protect this important cultural relic,the Luoyang Museum of Ancient Arts removed and restored the tomb wall paintings. The paintings were removed by using adhesives and gauze, and then Primal SF016 was used to penetrate and therefore enhance the paintings.Primal SF016 and fine sand were mixed to form an isolating layer. An alveolate aluminum panel was chosen as the support material. The damaged and lost area was completed by using the “Projected line method”.Now,the wall paintings appear in excellent condition after conservation.This work provides a good example for conservation and protection of wall paintings in China.
