Bone glue，a biobased harmless adhesive，has been used for the restorative reinforce of Chinese ancient lacquer furniture，but provided different adhesive strength on the different ground layers. This paper discussed the uses of bone glue at 25% in restorative
reinforce for broken lacquer film on the wood blocks，including three kinds of grounds，i.e. stucco with pig-blood，lacquer and titanium dioxide，which were tested by mechanical test machine. The structure of grounds layer and permeation of bone glue were observed by SEM，
as well as the gelation of bone glue.The results showed that the structure of grounds layer，permeation and gelation of bone glue would presented various effects on the bonding strength.The ground layer with pig-blood showed the most coarse structure，leading a better permeation of bone glue with less gelation，therefore increase the bonding strength. The grounds layer with lacquer and titanium dioxide showed fine particle structure that provided negtive effect on permeation and obvious gelation that reduced the bonding strength.
