To convert oil of tartar into a liquor.
[Drawing on page.] Take 3 or 4 lb. of tartar from white or red wine and put it in a large pot and cover it with its cover and seal it well around so that gases cannot escape and put it to calcine in a kiln or other furnace. When it is cool, remove it, grind it and triturate it on marble. Then put it in a clean and well-washed bladder and tie it well with strong twine and send it half-way down in the well so that nothing can hurt it and let it stay for at least 15 days or less and all will be converted into oily liquor. It will have properties different from the other in this respect that it does not give off gas and stays more united as a body. Its powers will be more potent. It will give identical effects and has the same virtues as the previous remedy of oil of tartar. Draw it out of the well and let it distill, bringing it forth little by little from the neck of the bladder. You will have a liquor from the oil very perfect for every use. Save it well closed. It can remove all the marks made on iron or glass and especially from silver. It has many other virtues such as are contained in the chapter above on oil of tartar.
Best and perfect oil made from virgin wax.
Take 2 lb. of good, new wax that has the odor of honey and cut it into very little pieces. Then take a good handful of little rocks as large as beans, neither more nor less, and wash it very well with pure water. When it is dried, put it with the wax and incorporate well together. Then put everything in a retort as you see in the diagram, very well sealed with lute of wisdom, made with trimmings from cloth or other appropriate things, to the thickness of a finger and let it dry well. Then place it on the little tower base with a grid of iron put in between and closed well from above, leaving there only its opening to let out smoke. Put on its receptacle well-closed with a cloth sealed around the opening so that nothing can escape from any side. Then make up the fire from charcoal or from dry wood, continuing it slowly for the space of half a day. The oil and the wax will come forth into the receptacle and in the retort will stay only the little rocks which are of no value. With your ingenuity, separate the oil from the wax in the receptacle because the oil stays below and the wax above. If you cannot extract it then break the receptacle and remove the oil first from its position and then remove the wax. Save this oil by itself in a double ampule, well-closed and it is done, oil of virgin wax in all its perfection. It has many properties and virtues, especially in fistulas. I have not seen a good miracle from it and for now I do not say more about it to you.
Note that if you redistill this oil one, 2 or 3 additional times, it is certain that it is reinforced greatly in its power and becomes perfect. This is the way in which oil of turpentine is made with these little stones well washed and with this retort, base and receptacle and with all the same rules which you must not vary and you will make oil of turpentine or oil of honey.... 149

Et coprila col suo coperchio et luttalo bene intorno chel non possa sfiatare et metilo a calcinare in una fornase de scudelaro overo altre fornase. Et quando sera fredo lo cava, pestalo e tritalo sul marmoro. Poi lo metterai in una vissicha che la sia netta e ben lavata et la lega bene con uno spago forte et mandelo cosi a mezo il pozzo che niente la possa offendere et lasselo stare al manco per 15 giorni o manco e tutto se convertira in liquore de olio. Et avera proprieta piu di quel altro as[s]ai arispetto chel non ne exalato e lo spirito e statto piu unito col corpo. Et le sue virtu serano piu potente et fara quelli medemi e effetti et a de quelle medeme virtu che a quel primo. Poi la caverai fora del pozzo et lasselo destillare da se a poco a poco fora del collo dela visicha et averai un liquore d’olio perfetissimo ad ogni prova et conservelo ben turato il quale smarisse tutti li segni fatti di ferro o di vetro et maxime quelle de l’argento. Et a de molte altre virtu como si contiene inel cap[el]lo sopra detto.
Olio di cera vergine, optimo e perfetto.
Rx. cera nova che sia bella e tenga al quanto di odore di mele lb. 2 e tagliela in pezeti piccolini. Poi piglerai una bona brancata di rena grossa como e fasoli e non piu ne meno et laveli molto bene con l’aqua chiara et quando serano asutte, li metterai con la ditta cera bene incorporate insieme. Poi metterai ogni cosa insieme in una bozza overo storta como tu vedi, la quale sia benissimo luttata con lutto sapiencie fatto con cimatura o altre cose hapropriati et sia grosso un dito et lassela ben sugare. Poi la comoda in questa torretta sopra a una graticcola di ferro acomodata inel mezo et serarato di sopra bene et lasatovi il suo buco solamente da mandare fora il fumo et meterai sotto il suo recipiente ben turato con una pezza luttata intorno ala bocha che neinte possa sfiatare da nissun lato. Poi li darai il foco de carboni overamente di legna seccha continuandolo lentamente per i spacio di mezo giorno. Et ussira fora l’olio e la cera inel recipiente et inela storta restera solamente quelle pietrelle le quale non sono de niun valore. Et col tuo ingegno caverai l’olio disseparato dala cera fora del recipiente perche l’olio sta disotto e la cera disopra. Et se tu non lo poi cavare, lo rompi et caverai prima l’olio per declinatione. Poi caverai la cera. Poi conserva el ditto olio da se in ampolla doppia e ben turrata e sera fatto, olio di cera vergine a tutta perfetione. Et a de molte proprieta e virtu et maxime a fistule. Io non visto un be[l] miraculo e per ora antro non te ne dico.
Notta che se tu restillerai questo olio una o 2 o 3 altre volte, sappi del certo chel se le rinforza magiormente le sue virtu e diventa perfetto. Et a questo modo si fa l’olio di trementina con questi fassetti minuti e ben lavati et con ditta storta con questa torre e con questo ricipiente et con tutto questo ordine medemo non preterire et farai l’olio di trementina et l’olio del mele.
