White bronzing on plaster
One needs to give four layers of painters’ glue in distemper on the plaster portrait, always leaving each layer to dry. Next, with mine d’Angleterre ground on a marble, or burnt lead, grind av & distemper with a bit of gum or go glue, lay down lightly. Once dry, rub lightly with a little cotton and the plaster portrait will seem to be of lead. Others grind minium with quicksilver.
Purpurine
The soft tin, half an ounce of, melt it in a spoon. Once melted, throw in an ℥ of ☿, mix together. Once cold, grind on porphyry. Next take an ℥ of sal ammoniac, an ℥ of sulfur, the yellowest that may be found, grind both of them. And then mix very well all the aforementioned materials. Next put all together into a a pignatta glass sublimatorium, hold this over a small fire for an hour & for an hour over a stronger one & for an hour over a very strong fire, and it will be done. Next, to use it, apply soot black with the glue that painters use to paint, & two or three times, until it is quite black. Next apply a little varnish. Once dry, apply the purpurine a secco with a finger where you want. The more you apply, the more beautiful it will be. Next, if you want, apply varnish on top.
White bronzing
Apply black with glue, as was said, on the medal, then varnish. Once dry, grate mine d’Angleterre on top with a pinceau or a finger. The said grated mine embellishes lead medals.
