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.
