100g of cactus powder is mixed with sodium carbonate and made into a paste, this is left for to react until the powders are dry. when they are dry, sunflower oil is poured on top of the dried powder cake. this is left for two hours with shaking. this is filtered multiple times until very clean, and vinegar water is added to the oil, once again left to react, with shaking. the vinegar water is evaporated in the oven on low.

heres where this differs from other food safe teks. it uses sodium carbonate as a base. this is really more of a question than a tek because i want to know if sodium carbonate will freebase mescaline from cacti powder. if not, would ammonia work? (just curious now, not food safe anymore)

yep sodium carbonate would work fine in this scenario.

wouldn't lime (CaOH) work as well? that is food-safe and a bit more efficient a base than sodium carb.

yes, but in my case lime is annoying to get, not impossible though, and anyone can get sodium bicarbonate and convert it. not everywhere sells lime
