Iron Transformed Into Copper

Dissolve blue vitriol in water, till the water is well impregnated

with it; and immerse into the solution small plates of iron, or coarse

iron filings. These will be attacked and dissolved by the acid of the

vitriol, while the copper naturally contained in the vitriol will be

sunk and deposited in the place of the iron dissolved. If the piece of

iron be too large for dissolving, it will be so completely covered

with particles of copper, as to resemble that metal itself.
