To make it bronze
Take pin and other brass filings, put them together, and grind it on marble, grind it well with water little by little, until it flows, and then put it in a new vessel and
when you want to use it, dilute it with very clear glue and coat what you like two or three times, then leave to dry. But before coating it with the bronze mixture (2 or 3 times), apply one coat of very clear glue and leave to dry. And after polish the bronze coat with a wolf’s tooth or dog’s tooth.
