Chapter XXXII The Manner of Applying the Said Colour
Let your work be dried with a clean cloth, then by means of a few feathers streak it over with the above concoction in the same way as you did when colouring the gold with the verdigris mixture. Then put it on the fire. When you see it drying and beginning to steam hard (do not let it steam quite dry) dip it in cold water. Then clean it up, & once again let it simmer slowly in the tartar solution189 for such space as you may say an Ave Maria; yet again clean it in water and polish it where you will. This gives the loveliest gilding and of the most beautiful colour that can be made, and lasts for ever.
