"The first section explains the physical and chemical properties which are important in the conservation process, i.e. application, aging, reversal. The topics covered include molecular weight, glass transition temperature, solubility and solvents, polymerisation and degradation reactions, adhesion, and uses. The second section provides detailed consideration of the individual materials, current and obsolete, used in conservation, drawing out the factors relevant to their effects on objects. The conservation uses of each material are summarised and referenced to allow further study"--P. [4] of cover.
