Then removing the ground and the wax at a heat,
Cleanse the surface with oil, spermaceti or sweet—
For your hand a performance scarce proper—
So some careful professional person secure,
For the laundress will not be a safe amateur,
To assist you in cleaning the copper.
Thus your etching complete, it remains but to hint
That with certain assistance from paper and print,
Which the proper mechanic will settle,
You may charm all your friends—without any sad tale
Of such perils and ills as beset Lady Sale—
With a fine India Proof of your metal."
