Query: A Minute to Learn, A Lifetime to Master

The Alchemist's Handbook by Frater Albertus is quite possibly the greatest and most concise piece of work on practical laboratory Alchemy known to man. Within a mere 124 pages, the author explains in detail the processes by which any would-be Alchemist may create herbal elixers. The process is simple and can be learned quickly and inexpensively. Mastering the Great Art that is Alchemy, however, takes significantly longer (I myself have been practicing for many years and still have not touched its surface). Frater Albertus does not, thankfully, fall into a deep and penatrating discussion of each elixer and its properties(of which there would be thousands), but rather explains how to create them and leaves the aspiring Alchemist to practice, study, ponder and create. In doing so, he insures that those who would like to venture into the Great Art have the capacity to learn it for themselves.
