Planing to do Noman plus Na2CO3 wash...
1. want to make sure this is the correct ratio for powdered bark:
1g mhrb : 22.5ml-30ml h2o : 1g NaOH
2. freeze precipitation...Are you better off using 4-6 jars for FP like the tek describes, or combining them all into 1 container for FP? Is there a difference, besides being able to separate your pulls?
well if you want to make that much water, its fine, but 15ml water should be enough...
as for freeze precip, you can put them all in one jar, but if its your first extraction, then if something goes wrong with one and you spill it or whatever, then you lose everything.. You know what they say, 'dont put all your eggs in one basket'. You can maybe put like, pull 1 and 2 together, 3 and 4 together, 5 (and 6 if you make) together.. Or whatever..
Another thing is that different pulls have different qualities sometimes. So sometimes the first pull is whiter/cleaner, while subsequent ones get more yellow, so if you mix it all you might have it all more yellow/darker.. But if its yellower/darker you can always recrystalize everything afterwards anyways.
But appart from these issues there is no real problem in mixing them up.
Btw do remember that for freeze precipitation to work the solvent needs to be saturated before going in the freezer, so its better to make more pulls (like 6) but make them smaller (like, say, 50ml per 100g mimosa). You can reuse the solvent after freeze precip for more pulls. Also remember if nothing crashes out, then evap half the amount and stick into freezer again.
