Is nothing else but linseed oyl, managed thus. Put it into leaden vessels, shaped like dripping pans, but so, that the oyl may not be above an inch deep. Set them out exposed to the sun for five or six months, until it becomes as thick as turpentine, the longer it stands the more fat it will be, and by consequence the gold will require a better gloss; if it arrive to the consistence of butter, that it may almost be cut with a knife, reserve it carefully, and is the best for use that can possibly be made.,,,
