"CorTen" or Corten is a weathering steel invented in the USA. It contains small concentrations of copper (0.25-0.55 wt%) and chromium (0.5-1.25 wt%), that help it develop a layer of patina. This layer of rust is more adherent and less porous than conventional rust. The latter in fact forms in the water in front of the steel and hence detaches easily, whereas the patina on Corten adheres. The major advantage is that little or no maintenance is required and the steel does not need to be painted.

This garlic has developed "rust" which is fungal and can also affect onions. The rust is apparent on the leaves. The garlic can be eaten but it stops growing. Photograph courtesy of Frank Abbott. |
