One of the main activities of the committee is the regular organisation, normally biennially, of scientific and technical colloquia, widely open to professionals. They are called Forums on the Conservation and Technology of Stained Glass and are organized by the committee board and by a national committee of the Corpus Vitrearum and/or of ICOMOS.
