PURPOSE: To obtain craftworks made of cast iron displaying local copper coating on the surface of iron casting, by placing copper plates or copper powder on locations corresponding to the locations where copper films are fitted in the mold manufactured corresponding to the casting, and by casting molten cast iron in it.

CONSTITUTION: Molds corresponding to the iron castings are manufactured and copper plates or copper powder are placed on places corresponding to the places in the mold where copper films of the casting are to be fitted. The molten cast iron is cast in the mold, and the casting is taken out after the cast iron is cooled. Thus required copper films are fitted on the surface of iron casting.
