The organ belongs to the core of European culture reflecting its diverse histories,
traditions and stylistic periods. The European heritage of the organ is preserved
in numerous historical instruments.
One major threat to this heritage is the indoor atmospheric corrosion of lead
and lead-tin alloys of organ metal pipes, constituting the central sounding part
of the organ.
The COLLAPSE project objectives were to define relevant methods and products
as well as to create conservation strategies in order to combat the corrosion of
lead and lead-tin alloy organ pipes:
- Through field studies and laboratory experiments to identify
the factors which cause indoor atmospheric corrosion
of lead-tin alloy organ pipes in order to avoid or improve
- To develop methods to clean, protect and preserve already
corroded pipes from further corrosion.
- To apply the recommended conservation strategies
in a case study using the historical Stellwagen
organ in St. Jakobi Church, Lübeck, severely affected
- To develop and present guidelines for a European conservation
strategy within this field, in order to contribute
to the safeguarding of an essential part of the cultural identity
which once was a driving force behind the creation of
European city life.
