Quote:After seven such distillations the water is called perfecta and after ten distillations perfectissima. Since this laborious procedure was very expensive, one was usually satisfied with four distillations. In the following period, several practitioners of alchemy used the same method to produce the aqua ignea rectificata (purified firewater) and finally the aqua vitae rectificata (purified water of life), which was used for medicinal purposes only.

There is no mention of the method being in code in the source quoted by Wikipedia (Holmyard, Eric John (1990). Alchemy. p 53)
