I don't see any reason why the proportions would need to be changed, at least, in theory. Just make sure that when you base, the solution turns jet black and there shouldn't be much to worry about.

It will work fine with powdered bark...that's how I did my initial extractions (also using marsofold's). The powder will eventually settle on the bottom like silt. Don't worry too much about getting some of the powdered material in your acidified liquid, it won't hurt anything. You can always put your jar of acidified liquid in the fridge at the end, let the particulates settle, and decant. Alternatively, you can add a little extra lye and they will dissolve in the high pH.

Hey, marsofold's Tek is cool! use a piece of shirt to squeeze out the remaining liquid. Also, check out revised tek of it!

Shouldn't matter much...the goal is really just to do an effective a/b. Isolate the alkaloids from the plant material via acid washes, base to a high pH (say 13), pull with non-polar solvent, collect alkaloids. The specifics of how this is done varies from tek to tek. I would say, do whichever appeals to you/you find easiest to understand, initially...at least until you understand the general principles of what's going on. Then, adjust to suit your situation/needs.


No need to buy a crock pot, you can do simmers or full boils on the stove. Personally, I use a pressure cooker and it works like a charm. Avoid aluminum...stainless steel pots are great. Remember not to pour your acid washes off into glass containers until they have cooled, so that you don't heat shock and break the glass. If you pour decisively, you shouldn't have too much spillage to worry about, but large kitchen funnels can make pouring from a pot/wide-mouthed container into a a narrow-necked container relatively simple and spill-free.

Hope that helps

if you use my pages, make sure to purify. I forgot to add that last step!
