Take 1 qt. Ball jar, add 600cc's cool, DISTILLED water.

SLOWLY add 100 grams 100% NaOH while gently stirring in WELL VENTILATED area. Wear old clothes, eye protection, and maybe even gloves. Water will get quite warm to touch...go slow...stir often...stay upwind...and ALWAYS add powder to water, never, ever add water to powder.



When basified solution is made and clears, measure out 100 G highly pulverized MHRB and add to jar of basified water. Note: Although the scale shows 50.24 grams of NaOH, the FOAF measured this out twice for a total of 100 grams, per accompanying text.



Place lid on jar and swirl to wet and "sink" all the powdered bark. Solution will turn a dark purple-black.
Congratulations, you just finished the hardest part, which should have taken all of 1/2 hour if you previously macerated your MHRB.



Notice how we still have plenty of room to add VM & P naptha...LATER. For now, set aside the jar in a secret, undisturbed place at room temperature for minimum of 24 hours to allow the basified water to break down the cell walls and release spice into solution. Tick, tock, tick, tock...DING!

Ok...so, it has been 24 hrs since MHRB has been soaking in the basified water. Time to add exactly 150cc's VM & P naptha to the jar. Cap snugly and put aside in a WARM place, a Get jar to about 80 - 85 degrees. 1 HOT BATH is good Feel free to invert, roll, swirl and otherwise mix the layers together several times per day for one day...with this concentration NaOH no emulsion will form...unless you shake vigorously, which may result in an emulsion. Swirling alone works quite well!!!!

NAPTHA PIC TO LARG USE VMP NAPTHA

After 24 hours, your naptha will have a yellow cast. This is GOOD! Note: Perhaps I should have said "mandatory." A pale urine-yellow cast is indicative of migration of spice into the naptha. You probably should NOT proceed to the freeze-precipitation step if your naptha remains clear. It should look VERY MUCH like the two pictures below, before proceeding.



Use your turkey baster, and remove ~HALF the naptha, or 75cc's and place it in your 1/2 pint jar. This will insure that you leave a nice layer of naptha without soaking up ANY NaOH water. Don't worry one bit about the naptha left behind...you'll see why in a moment.

Note how CLEAN the naptha is. No amount of basified water contaminant should be tolerated.



Cap the 1/2 pint jar and put it in the friggin coldest freezer you have. I use an old meat freezer we keep in the garage. Freezer should be cold enough to freeze ice cream solid. 24 hours later, you'll have crystals, like this on the bottom and sides of the jar.



Slowly, carefully pour the naptha back into the basified water, leaving the crystals, which will stick to the glass, behind. Allow every pourable drop of naptha to exit the jar and you won't have problems with crystals re-dissolving back into any minor residual naptha as it warms. Don't worry about the "floatie" protocrystals in the cold naptha solution you poured back...we'll get 'em all eventually.

Put the 1/2 pint jar aside to allow the crystals to COMPLETELY dry. A nice dark, warm dry place where air is free to circulate is just fine. It'll look like this:



When completely dry, use a razor on a handle to gather your powder, and transfer to a sealable baggie or whatever.



The residue in the 1/2 pint jar will be re-dissolved in another 24 hours when you again remove 75 cc's of "recycled and recharged" naptha from the basified water. So...basically you will repeat and repeat and repeat the removal of naptha with the baster, freezing, etc. several times, until the yield really drops. Please note that subsequent extractions will yield increasingly yellow product, in ever decreasing amounts. This is normal. I've taken to combining all powder. You, of course, may do as you see fit.

As a final step, you can remove as much of the naptha as possible w/o getting NaOH, evap down and get the last drop of spice.

Id use less naptha and make more pulls, say like 40ml/pull by 3 or 4 pulls, mixing for longer. Like this you are getting really saturated solvent, making it easier for it to crash out in the freezer.

Id also mention that yellow doesnt specifically mean you have only spice, you are pulling fats/oils too, thats what making it yellow. Ive pulled clear naptha that was super saturated with spice.

Take a look around the extraction tek's on the wiki, I think you will like some of the tek's there.

That's a pretty good tek, couple notes:

1. Use a little more NOAH(10-20g) to really attack the material, I've found that this helps 100% of the time.
2. Go ahead and add your naptha right after you basify. The heat generated by the reaction will help to suck some of the spice into the naptha quicker. I Usually add naptha after basifying, roll it around and let it set...repeating your rolls everytime it seperates. this will give you a NICE first pull after 24 hrs.

Yes you cant never really add to much lye :idea:

-

Is it possible to substitute Calcium Hydroxide for the Lye while using this tech? What is the PH we are shooting for? Can it be obtained using Calcium Hydroxide/Pickling Lime instead of Lye? If the answer is yes, are there any additional steps one needs to take or additional time needed?

I'm new here and learning lots.

Thanks!

if you want to substitute calcium hydroxide(lime) for lye, then you will want a different tek designed for its use. (limetek or drytek) it will usse much less water, have a vinegar pre soak, and can utilize different solvents, depending on what what you are after.

go food grade

Thanks for the info. Are there any noticeable differences in yield between a tek using lye and one using lime on the same bark? If so, which one yield more?

To the OP, how much spice did 100g MHRB yield you using this tek?

It has been reported that a properly done drytek can get as good a yeild as a STB tek. I imagine that for your first go, you could expect the same yield.

Any tek makes so much more sense after you go through it once. You will get the hang of it quickly.

I have used this tek a lot, and always get roughly 1g of spice from 100g of bark (3 or 4 pulls).

Altough that might increase using the tips mentioned in this thread

SWIM did STB extractions many many times, and he think a/b probably gives a little better quality spice. It is much easier to breakthrough of a/b spic rather than spice from a stb. his personal opinion at least..

This seems fair enough, but emulsions will be easy to form with this one... try more water, It can never hurt. And bottles with a stem where the naptha can collect and be drawn off easily without sucking up mimosa soup.
