vi Preface
good introduction to the subject and we hope that it will be a valuable reference
work and precious reading companion for both students and professionals.
The text is divided into chapters covering analytical aspects, organic materi-
als, inorganic materials, wall paintings and in situpreservation. Contributions
are from a wide range of practising international experts from leading research
institutes who outline the problems and provide many interesting and excit-
ing case studies. The text offers a basic introduction to the science of heritage
materials, their deterioration and restoration processes. The complexities and
problems faced by conservators and scientists are addressed together with the
processes of decay and degradation that affect ancient materials. It describes
in detail the processes of decay and degradation for each major category of
material (paper, wood, stone, glass, metals, leather, plastics etc.). The chapters
on plastics and in situconservation provide insights into the rapidly developing
new areas of conservation science.
A word here about topic coverage and our policy on referencing. These are
generally full with topics where there exists no adequate books or review
articles – metals and wood are cases in point – and, as a consequence, there is
no necessary correlation between length of a chapter and the practical impor-
tance of the subject. In relation to the references, we have adopted a non-
referenced style and provided reference sources and further reading at the end.
This book is clearly the product of many specialists and the editors are con-
scious that without their input it would not exist. It has had a very long gestation
period. There is never a good time to edit a book; it is a labour of love that sur-
passes all understanding and common sense, measured against the increasing
pressures of academic life. The contributions have come in over a long period
and in that sense we are grateful for the understanding of not only the authors,
but the RSC, particularly Janet Freshwater and Annie Jacob, who have cajoled,
but mostly supported, us throughout a prolonged delivery. We are also grateful
for assistance and help from our organisations, namely, the Mary Rose Trust
(MJ) (notably Andy Elkerton with the index) and the University of Portsmouth
(EM). This could not have happened without the support of our families,
especially Helen and Jeannette. We hope you enjoy the final product.
