The importance of analysis in art restoration

In order to choose an intervention methodology for the conservation and art restoration one of the fundamental steps is the analysis of the work itself.

In conservation and restoration, diagnosis is a fundamental step for art restoration . Conservation of paintings online course

It not only allows us to identify the pathologies and degradation processes of the work but also its constituent materials and original production techniques.

There are various methods of examination and analysis that can be used to obtain a great deal of information.

For example, how to verify the form of execution, elements that are part of the original constitution, elements added later, methods of execution, damage, degradation, among others.

A critical observation of the work is the first step towards a correct diagnosis and the determination of the necessary analysis and diagnostic methods.

This type of analysis helps to determine:

  • physical stability,
  • the different degradation materials deposited on the surface,
  • possible biological attacks,
  • general state of conservation.

art restoration and conservation | physico-chemical methods

After the general analysis, physico-chemical methods based on 2 types of examination are used.


They essentially use radiation that is visible or invisible to the human eye to determine important aspects for art restoration , for example:

  • Elements constituting the work,
  • Methods of assembly,
  • Use of metallic elements,
  • Application of polychromies.
