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 solution[189] 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.
