Chemical Preservation


The Archaeological Survey of India's Science Branch is responsible mainly for the chemical conservation treatment and preservation of some three thousand five hundred ninety three Protected monuments besides chemical preservation of museum and excavated objects countrywide.

The real challenge before us is to plan the necessary measures of preservation with a view to assure the survival of these built cultural heritage and unique symbols of our civilizations for centuries to come, with as little intervention as possible but without altering or modifying in any way the authenticity of their original character. To ensure the stability as well as proper preservation of our cultural heritage, there is a need to give more thrust to the scientific research in preservation options must be based on a preliminary investigation which includes the knowledge of physical nature of the object (constituent materials, architectural characteristics, production techniques, state of decay) and of the factors which induce or could induced its decay. In other words, as in the case of medical study the field of preservation therapy to be based on a correct diagnosis.

The role of scientific discipline is vital to both these steps of preservation activities. Accordingly, a specific objective of scientific research activities in preservation being carried out by the Science Branch is aimed to study:

  • Material deterioration process.
  • Basic studies of intervention technologies.
  • Basic studies on materials.
  • Diagnostic technologies.

The main activities of Science Branch are:

  • Chemical treatment and preservation of about 5000 centrally protected monuments including 18 world heritage monuments.
  • Chemical treatment and preservation of museum exhibits and excavated objects
    Scientific and technical studies as well as research on material heritage of different building materials to study the causes of deterioration with a view to evolve appropriate preservation measures in order to improve the state of preservation of our built cultural heritage and physical heritage as well.
  • Chemical preservation of monuments and heritage sites abroad.
  • Technical assistance to state protected monuments as well as built cultural heritage under the control of trusts in the form of deposit works.
