About this course

This course covers the conservation of structural metalwork, architectural features and statuary, and includes both ferrous and non-ferrous metals, with tuition from leading practitioners on a wide range of repair techniques.

It also includes the methods of manufacture and shaping of ferrous metals, the history of their use, deterioration, surveys, practical cleaning methods, surface preparation and coatings, and specifying metalwork repairs. It covers corrosion science, the latest developments in cathodic protection as a remedial solution to rusting cramps and the science of traditional electrotype forming as used for statuary.

There will be a 'hands-on' opportunity in the Forge when students will be able to try out traditional and modern techniques relevant to architectural conservation such as forging at the hearth, arc and gas welding, flame cutting and needle gunning.
