HUOM.! ORPIMENTTI ON ARSENIKKIA, MYRKYLLISTÄ!
AURUM MUSICUM, AURUM MUSIVUM, a sort of liquid gold for writing;

Take fine crystal and orpiment of each one ounce, pound them severally, till they are reduced to a very fine powder, then grind them together well with glair.

With this you may write either with pen or pencil, and the letter or draught will be of a good gold colour.


Another way of making the same.
Take of the best English tin, an ounce, and of the best spanish quicksilver the same quantity: make of them an amalgama, by putting the crude mercury to the melted tin, and stirring together; then reduce them by pounding into a fine powder, and mix them with flowers of sal armoniack, and flowers of sulphur, of each an ounce: calcine gently, till the sulphur is consum’d, and so will the Aurum [gold] stick to the upper crust or scoria.

This being finely powder'd, and ground with glair, will with pen or pencil give your figure or picture a golden colour. See 2d. Ed. Pharm. Bat.
