Coated Iron Wares
The principal drawback which has always attended the use of iron and steel
is the great tendency of the metal to rust or corrode. Not only does it rust
easily, but when the process once starts it proceeds rapidly, soon destroying
the article. Iron differs from most metals in this particular. In all other
metals the deposit formed on the surface of the metal protects it from further
corrosion. This is seen in the case of copper, which is used for the rain spouts
of buildings. In a short time the atmosphere causes a beautiful green coating
to appear, and this is a protection to the metal.
Many methods have been devised for protecting iron from air and rust, such
as enameling, tinning, galvanizing, painting. All except painting are used in
making some of the articles among house furnishings products.
Making the Foundation
The iron or steel foundations for coated ware are stamped out by dies from
sheet iron or sheet steel, a separate die for each "size" of each utensil.
