Thanks for the advice tryptographer. But SWIM will try the acid cleanse next time he told me.He feels almost to bliss over his success and wants to make changa now..and thanks for the information about lye. Now i feel kind of more safe.
And just to report my friends success..SWIM did´n get the quantity he expected, only 300mg from 50g. Most of it (aprox 98%)being white and clean. There are some residue(spelling?) left in the bowls, kind of oily, not much but oily anyways. But he is planning on cleaning the thin layers of snowfalkes that are left in the bottom of the used bowls with acetone, put the acetone in a bigger pyrex dish, put the clean spice in it. Then enhance some leafs, making his own changa.
The ratio SWIM is going to use to enhance leafs is 1:1.5. That would be +300mg of spice with a total of aprox 500mg of leaf..caapi and damiana with a pinch of x7salvia. For light, force, taste and synergi hehe..
But SWIM is kind of dissaponited, he thought that he could pull 500mg of spice like many other SWIY
But being SWIM´s first try he feels content with 300mg and the best part is to have succeeded he told me.
So, once again nexus..SWIM says thank you folks and now he is going to start making his own changa..
