Efter hvad jeg kan læse mig frem til er det ret ligegyldigt bare basen er stærk nok hvilket kaustisk soda er. PH'en skal så være omkring 10,5 og vil herefter reagere med carbon dioxid i luften og PH'en vil blive sænket nok efter flere dages rulning og iltning iltning om så man kan kalde det.
husk dette er blot hvad jeg har læst mig frem til.

http://en.wikipedia.org/wiki/Anadenanthera_peregrina"To make the psychedelic snuff called yopo, the black beans from the bean pods of these trees are first toasted until the beans pop like popcorn breaking the bean's husk. The roasting process facilitates removal of the husk and makes the beans easier to grind into a powder. The bean's husk is usually removed because it is difficult to powderise and adds unnecessary volume. The bean is then ground with a mortar and pestle into a powder and mixed with a natural form of calcium hydroxide (lime) or calcium oxide (from certain types of ashes, calcined shells, etc.). This mix is then moistened to a consistency similar to bread dough, using a small amount of water. If calcium oxide is used, the water will react with it to form calcium hydroxide. Once moistened, it is kneaded into a ball for several minutes. After kneading, it is then left to sit for several hours to several days, depending on the local customs. During this period most of the excess calcium hydroxide reacts with the carbon dioxide in the air to form less caustic calcium carbonate (carbonatation)."
