For 50g of bark, id start with say 60 to 70g of lye, you won't realy need to add more unless you add too little to start with. rememebr to add it slowly and have a basin of cold water to cool the bottle in as it is an exothermic reaction.
Well th efirst part of the xylene tek is the same in terms of pouring some in the mix and seperating it.
then one dries some acetone with baked epsom salts and saturate that with fumaric acid, this gets added into the pulled xylene dropwise, makes these real cool milkey smokey swirls.
Anyhow, when you are done with this step you are left with DMT-fumaric salts and some excess fumaric acid deposits, so you wash the mix with some dry acetone.
NExt you use some baked bicarb of soda 1:1 ratio with the salt xtals you have seperated and dried (it dries fast) and a few drops of water to work it into a paste and form thefreebaseand let it dry while crushing any particles.... DMT freebase is soluble in acetone... now you perform a number of small washes with acetone and collect them together. Evaporate this to form a plate of earwax like DMT freebase + jungle spice. Use very small bits, this stuff puts normal DMT to shame whne it comes to potency.
