Water-gilding Upon Silver

Take copper-flakes, on which pour strong vinegar; add alum and salt in
equal quantities; set them on a fire, and when the vinegar is boiled,
till it becomes one-fourth part of its original quantity, throw into
it the metal you design to gild, and it will assume a copper colour.
Continue boiling it, and it will change into a fine gold colour.
