Reflecting on what is restoration and conservation is extremely important for all those who work in related fields of activity: conservators, restorers, museologists, archivists, etc.
But also for all those who have in their care objects of heritage value, whether they belong to the public or private Cultural Heritage (family, for example).
This article aims to systematize the concepts of conservation and restoration and answer the question – what is restoration and conservation – based on the specifications of ICOM (International Council of Museums).
What is Restoration and Conservation
Let’s reflect on:
1 – Why conservation and restoration actions are necessary.
2 – What is restoration and conservation and what are the different levels of action.
3 – We will also indicate some useful links for the development of the theme.

Why are conservation and restoration actions necessary?
Objects are created to accomplish a certain function, which can be aesthetic or functional.
Over time these objects gradually degrade for a number of reasons:
- due to the nature of their constituent materials.
- due to the environmental conditions to which they are subjected.
- due to inappropriate use or even vandalism.
What is the purpose of Conservation and Restoration
These concepts correspond to different levels of action on the object.
– Preventive Conservation
– Remedial Conservation
– Restoration
what is restoration and conservation | how these concepts are applied in practice
Preventive Conservation
infestation control is one of the aspects of preventive conservation
Preservation (preventive or indirect conservation)
does not act directly on the object, but eliminates the potential degradation factors, that is, intervenes in the environment where the object is located.
Examples:
Measures and actions required for registration, storage, handling, packaging and transport.
Control of environmental conditions (light, humidity, air contamination, insects).
Emergency planning, education of professionals, public awareness, legal approval.
These preventive conservation actions are essential to avoid degradation processes that can be destructive to works of art.
But also to avoid the need for much more complex curative conservation and restoration actions, with much more intervention on the objects and sometimes financially impractical.
Next we will see how the concepts of curative conservation and restoration are applied in practice.
Remedial conservation
Conservation (direct or remedial conservation)
acts directly on the object, interrupting or delaying its degradation.
Examples:
Disinfestation of textiles, disinfestation of wood, desalination of ceramics, deacidification of paper.
Dehydration of wet archaeological materials, stabilization of corroded metals, consolidation of wall paintings, stabilization of canvas.
Restoration
Actions on the object that aim to restore the aesthetic value by returning the object to its readability and comprehension.
These actions only take place when the object has lost some of its meaning or function through alteration or deterioration.
The restoration of cultural objects is thus the last and deepest level of intervention.
Restoration actions must be very well thought out and justified.
Examples:
The process of putting together fragments of a piece that had lost its function and reading.
Chromatic reintegration of paintings, assemblage of a sculpture with gaps, reintegration of gaps.
what is restoration and conservation | when are interventions justified?
Levels of Operation
Preventive Conservation
Action on the object
No action on the object
Objectives
Preserve the external conditions necessary for the longevity of the object
Intervention timings
Permanent – The preservation conditions must always be safeguarded
Remedial Conservation
Action on the object
Act on the object
Objectives
Interrupt or delay degradation processes
Intervention timings
When degradation factors are verified
Restoration
Action on the object
Act on the object
Objectives
Return reading and/or function to the object
Intervention timings
Only when the object has lost its readability or function
