Further Details About This Book:
Conservation of historic monuments is a means of continuity with history because it
keeps alive the cultural scene of the period to which they belong. The world is rich in
various types of built heritage, and a large proportion of monuments are made of stone.
Stone artworks come in various forms: mineral specimens, sculpture, jewellery, tools,
fossils, cave paintings, buildings, and bridges. Some are resistant if used outdoors on
the ground, whereas others are more fragile and brittle. If stone artworks are handled
inappropriately, they can break.
Deterioration of stone is familiar to anyone who has looked closely at a historic
building or monument. A few stones seem little affected by centuries of exposure to
the weather, but most are undergoing gradual deterioration by weather and pollution.
Hence, stone-based cultural heritage is slowly (but inexorably) disappearing, inducing
investigations focused upon it.
An understanding of the mechanisms responsible for stone decay is needed to develop
optimal methods for stone protection, and is the basis of a conservative approach.
To reach the goal of preserving stone-based materials, describing stone decay as
well as measuring its extent, severity, rate, causes and mechanisms, is essential.
Investigations related to stone deterioration must take into account the wide range
of types of rocks having different mineralogical and physical characteristics and their
varying weathering responses under different climatic and environmental conditions.
Afterwards, suitable methods and materials may be studied and set-up to help the
stone to survive. In response to this, numerous research projects, publications and
conferences dealing with stone conservation have facilitated the worldwide exchange
of information.
