In my experience with LexTex and this DMT handbook, a pH lower than 12 leaves acacia brews frothy and unwieldy (ie, unable to siphon.) With especially fresh acacia bark, ive found even higher may be necessary, ie 13-14. For the record, this is with 5-6 yr old A. Acuminata bark.

Personally i prefer to use the defatting method in LexTex over recrystalization! I find it produces a much purer product, ie without rextalization i was able to grow pure clear (not white) crystals, some as big as ~4mm. And this from VERY oily acacia bark.

Oh and, if you're siphoning naptha/shellite, a drop on the tongue never hurt... just watch out for the NaOH mix Hehe

Edit: (Added a few more pointers ive learned the hard way)

- Ive found a thin siphon (2-3mm diameter, ie aquarium pump tube) works better than thicker stuff as it runs slower and thus allows more precision. Also use round or flat bottom jars (not HDPE jugs with corrugated bottoms! it makes siphoning the last bit very difficult!)

- Barks vary. When doing the defat and acid-washing the shellite/dmt/plant-oil solution, i keep pulling until the pulls stop raising in pH. Ie, if im using a pH 3 wash, the first pull will likely be neutralized, the second pull might be 5, third 4. In this scenario i would do a fourth small pull which should come out close to 3 meaning little dmt is left in the shellite mixture.

[QUOTE="fiveseven, post: 3237948, member: 4209"] In my experience with LexTex and this DMT handbook, a pH lower than 12 leaves acacia brews frothy and unwieldy (ie, unable to siphon.)
