Conservation of Glass, first published in 1989, was intended to serve as a textbook for conservation students, conservators and restorers working on glass artefacts within museums, and those restoring painted (stained) glass windows in situ. It was written by two authors with very different, but complementary backgrounds and experience in the conservation of glass. Roy Newton, a glass scientist (now retired), has worked in glass manufacturing, on the archaeology of glass and on the problems concerned with the conservation of medieval ecclesiastical painted windows. Sandra Davison, a practising conservator for over thirty years, has conserved a great variety of glass artefacts, published and lectured widely, and teaches the principles and practice of glass conservation in many countries.
