To make Bronze, or powder of the colour of gold.
Take of gum-elemi 12 drams, melt it; of crude mercury, one ounce, sal-armoniac, two ounces; put all into a glass-vial, with bole and whites of eggs: melt all, and when melted, add orpiment at discretion, with some filings of brass; being well mingled together, lay it with a pencil on that which you would bronze.

How to Bronze.
Having whited and made your figure smooth, grind crystal and touchstone with water, temper it with glue, and lay it on your work; instead of burnishing, rub the metal of which colour you would have, well, and it will be finished.

To bronze with copper.
Take pin-dust, grind it well, and wash it till the water be quite clear, mix it with glue, as you do tin-glass; lay it on the white ground with a pencil, and burnish; the same may be done with antimony.
