Using 200 grams of ACRB I did 5 45 minute acid boils  and was going to  [freeze percip] also use the newest defatting method...but i did not defat...and didnt  use a freezer either and it hard to believe how well thgis worked...
Just using what i know...which is a mixture of two or three tecs... acid boils... plenty of salt and fair amount of lye  hot water baths on soup alowing for seperation..
What i did was cause an over saturation in my napatha and thick crystals formed  in booth jars
My first couple pulls had yellow napatha and i thought it was  all impuritys in that jar but after setting overnight huge crystals started growing in bottom of jar!
Ill try to send photos of my crystals..you can see mount olimpus growing in bottom of pull jar with yellow napatha...
Then i noticed that  about pull three or four the napatha looked much lighter in color and crystals were  forming all over the bottom and sides of jar...
My bark was high quality root bark and since crystals were forming into a thick white sludge in the jar i just poured off the napatha in another jar and quickly put a fan in front of tilted didh...
I wanted to try freeze percip method but the crystals were already developed!
