If you want the red copper color without the patina, a quick spray with a decent clear coat or a proper metal polishing oil/wax can protect the surface. The cool thing about copper plated items is that the copper plating allows you to plate it with other, trickier metals. For example, nickel doesn't like to adhere to some steels without some coaxing.

Materials Process. Bronze, steel, iron, brass, copper, and aluminum are just a few of the many metals that can be converted to powder and undergo the metallurgy process. The sizes of these powder materials are categorized by mesh powder, which is a measure based on the size of mesh openings through which the powder can pass.

Copper sulfate can be prepared in the laboratory by reacting various compounds of copper (II) with sulfuric acid. However, it is commercially available on a largescale basis, and is an economic source of Cu. Copper sulfate pentahydrate readily dissolves in water and is also soluble in methanol, glycerol, and to some extent in ethanol.

The process is highly efficient and a large amount of raw material can be processed in relatively small furnaces. The copper matte and slag are tapped into another furnace for settling and separation. The copper matte is then run into another furnace and air or oxygenenriched air is blown in, to produce copper .
