A Water To Give Any Metal A Gold Colour
Take fine sulphur and pulverize it; then boil some stale spring water;
pour it hot upon the powder, and stir it well together; boil it again,
and pour into it an ounce of dragon's blood. After it is well boiled,
take it off, and filter it through a fine cloth; pour this water into
a matrass, (a chemical vessel,) after you have put in what you design
to colour; close it well, and boil it a third time, and the metal will
be a fine gold colour.
