| Cor-Ten Sculptures |
|
As Cor-Ten becomes ever more popular for outdoor sculpture, conservators are playing catch-up on preservation techniques.
Like ordinary steel, the way it is used in sculpture is conditional on the forms in which it is produced which are mainly plate rod, flats and structural sections (
Ordinary steel surfaces can be treated after the work has been completed and sculptors have used everything from powder coating through paint to acid etching.
Cor-Ten, on the other hand, is normally used out of the mill and because of the rough, purple – brown surface that is eventually revealed when its rusting stabilises.
That means that most Cor-Ten sculpture is found out of doors. It also means that, in fabricating the sculptures we have to take a great deal of care when we are welding and grinding, also mixing with other materials. When we don’t the conservators eventually get interested – although British sculptors are amused by the idea of needing to conserve an essentially found material.
