The present volume contains the panels and fragments encountered and researched by the authors since they started their research more than thirty years ago. Many of these panels and fragments are totally unknown to the public as they have never been displayed, nor published. Nevertheless they demonstrate an important aspect of stained-glass production and stained-glass conservation. Where large windows in churches are well known to the public, it is often forgotten that even more stained glass was created for dwellings of the noble or patricians, house chapels, guild rooms, smaller spaces in abbeys, etc. It also became clear that virtually no glass was thrown away and larger fragments and panes were recycled as 'stop gaps' or integrated in composite panels, the so called 'vitraux d'antiquaires'. Furthermore archaeological sites nearly always reveal quite small pieces of glass, which could not be used for repairs or as 'cullet' in the glass production cycle. A selection of these archaeological finds is also presented in this volume. At the end of this volume 'Addenda' to the previous volumes are also added.
