The development of a rigorous conservation methodology for Cave 85 aimed to create an approach—rather than a formulaic response—to the treatment and long-term preservation of the wall paintings. This methodology and process is based on the China Principles and is intended to be applicable and adaptable to other Mogao cave temples and similar sites in China. Emphasis is placed on the identification and understanding, through investigation and research, of the causes and mechanisms of deterioration in order to test and implement appropriate conservation strategies.

Each phase of the project was carried out in close collaboration with the Dunhuang Academy.

Component One: Information Gathering and Assessment
Research, compilation, and review of background information relevant to Cave 85 and the site to provide context for the assessment of significance, management, and condition, and to better understand the problems and the causes and mechanisms of deterioration.

Component Two: Testing and Development
Development, through research and testing, of intervention strategies based on information collected during the assessment phase to preserve the cave through preventive measures and remedial treatment.

Component Three: Implementation, Monitoring, and Maintenance
Execution of the work, including preventive measures and remedial treatments and the development and implementation of monitoring and maintenance programs.

Component Four: Presentation and Interpretation
Development and implementation of a safe and appropriate visitation policy and measures that will enhance the visitor experience.

Component Five: Training and Dissemination
Training and dissemination of the project methodology and results.
