SWIM decided to use a STB-Extraction because SWIM doesnt like too much acid in his house.Well, the base is so much worse, actually. An A/B-procedure contains one acid step, but you only have a pH of about 4, when you in a standard STB have a huge excess of base. Just wanted to make sure you knew this. STBs are easier for beginners, so go for it.
What is actually the best fluid to delute the DMT after breaking the MHRB? I know Naphtha is a very general word and every brand puts other stuff inside it (and its actually hard to get here on Alpha Centauri). What solute is SWIY using? Heptan/Hexan/Toluole or something else? Whith which substance does SWIY have the biggest yields?Dilute? You use a solvent to dissolve the freebase DMT which works because of it's insolubility in water. Heavy naphtha is about the best you can use for pulling from the bark, but it also pulls a lot of other stuff, and it freezes bad. Light naphtha pulls good amounts of spice as well as a little less amounts of impurities. It freezes good and evaporates alright, highly recommend it. If you can, I also suggest you get some pure n-heptane or n-hexane, for recrystallizations! Don't use xylene/toluene, they will pull "jungle spice".
Before you use your naphtha/heptane you should do an evaporation test to make sure it's clean.
What is the best way to heat the solute (as some dangerous gases can develop while heating)?This is a bit misleading. The danger would be your solvent evaporating, and the vapors can ignite. Use a heating method that does not involve any open flames or sparks, a heat bath is a great idea.
How much time should SWIM give the heatet solute to catch the Spice? (What are SWIY's experiences?)It's not as much about time as it is about mixing. I roll it around firmly for 3 minutes and then let it separate. This I repeat three times. You will quickly learn how roughly you can handle your solution without emulsions forming.
How cold (in c° has SWIM's freezer to be? (Because SWIM has an old freezer that is not THAT powerfull)Colder is better. If you're at or below -20°C you're fine.
There's a clear difference between what I say I do and what I actually do perform.
