Restoration

Restoration is defined in the Burra Charter as returning the existing fabric to a known earlier state by removing accretions or by reassembling existing components without the introduction of new material.  It is not the same as the re-leading of a window which is more aptly defined as reconstruction.  However, in the field of conservation a number of different forms of intervention may be required in order to return a window to a known earlier state.

This example shows the before and after section of a window that had undergone heavy handed repairs on at least five earlier occasions.  Each intervention introduced new materials and at one stage the whole lead matrix was completely replaced with an inferior quality lead alloy that had since failed.  Broken glass had been repaired by the insertion of ‘mending’ leads or simply replaced with unpainted or poorly matched new glass.

The restoration process involved removing all of the introduced ‘mending’ leads and repairing the glass breaks using less intrusive methods.
