Principles and problems in conservation.
Brickwork, with tile and terracotta, is one of those materials so
universal, so apparently permanent and so much part of our everyday
lives that its conservation is presumed to be understood. This is
very largely untrue. Most brickwork is cursorily maintained and
often subject to serious abuse. Neglect and clumsy repair are all
too frequent, and the really skillful repair based on a full understanding
of the mechanisms of decay is all too rare.
