To Give Silver The Colour Of Gold
Dissolve in common aqua fortis as much silver as you please. To eight
ounces of silver, take four ounces of hepatic aloes, six ounces of
turmeric, and two ounces of prepared tutty, that has been several
times quenched in urine. Put these to the solution of the silver; they
will dissolve, but rise up in the glass like a sponge; this glass must
therefore be large, to prevent running over. Then draw it off, and you
will have ten ounces of silver as yellow as gold.
