The most interesting galvanization process which also yields
the best results in a qualitative way is the wire galvanization process known
as the Crapo process. The wire obtained by this process and the brought on the
market has a zinc coating of from about 900-100 gram, and is flexible in every
way without a loss of zinc coating. According to the specifications of the
patent, this remarkable effect is obtained by the passing of the wire, previous
to pickling and galvanizing, through a lead bath having a temperature of from
700-800 degree which on the surface of the wire discharge region is covered
with a fluid solution of salts which may consist of chemicals. After passing
through this salt smelt, the wire should be pickled and galvanized in the
ordinary manner. It is true that the patent puts forward no possibility of
explaining the occurrence of these effects.
