aight buddy here you go...
take your tar and throw it at a homeless man claiming it to be god or....
put tar in pyrex open deep dish (pyrex for the exothermic reaction, deep dish for splatter control and housing liquid)
add dry lye
add minimal water to bassify alkaloids
stir into homogenous solution of syrupy goop
add NPS, and swirl
watch the nps get funkified, if nothing changes in the color of the NPS, pour it off (save it!) and add more lye/water and mix it into the tar for a higher ph to ensure the mescaline has been freebased
add the NPS again, swirl again
isolate nps
pull nps with acid solution (10 ml 30% hcl diluted with 50 ml distilled water, this is enough for 2 salts) (or distilled white vinegar)
let salts precip/separate for 15 minutes after vigorous mixing
swirl one more time to collect salts in aqueous layer (bottom layer)
separate salts and evaporate
OPTION 1 - enjoy dirty acetates or clean with some technique you find
OPTION 2 - take your dirty hydrochlorides and wash in cold anhydrous acetone, pour through thick cotton filter, take cotton filter and add 15 ml hot water to dissolve the clean captured mescaline onto an evaporation dish, evaporate and really enjoy ( i prefer a gram, nothing less ) save cotton filter for further use or repeat the hot water dissolving to ensure all product is retrieved
peace bra!
