CHAPTER XXX. HOW TO MAKE THE WAX FOR GILDING.

Take five ounces of new wax, half an ounce of red chalk (that is to say, red stone chalk for drawing[184]), half an ounce of Roman vitriol,[185] three pennyweights[186] of _feretto di spagna_,[187] that is of the weight of a ducat, or one-eighth of an ounce, or it may be a bit less, half an ounce of verdigris, & three pennyweights of borax. Mix all these things together and melt them with the wax, & apply them as above described. After this, when the wax is cleaned off, you can give it the colouring that follows hereunder.
