This technique is a combination of several that I've found.    Here is one Tek to where I am today...      1. Premix in an empty 1-Gallon plastic jug: 1-Pint White Vinegar &amp; 3-1/2 Quarts Water.     2. Put the ground up Mimosa in a 3-Liter crockpot, then fill it with the water-vinegar solution.     3. Stir well and turn it on "high". After 2 hours, remove the crockpot ceramic liner, hold the lid on slightly offset, and pour 50% of the liquid into a 1-gallon wide-mouthed glass or stainless container.     4. Add the remaining water-vinegar solution to the crockpot again. Stir well and turn it on "high". After 2 hours, remove the crockpot ceramic liner, hold the lid on slightly offset, and pour off 25% of the liquid into the same container again.    5.  Add the remaining water-vinegar solution to the crockpot again. Stir well and turn it on "high". After 2 hours, remove the crockpot ceramic liner, hold the lid on slightly offset, and pour off the final 25% of the liquid into the same container again.    6. After the last extraction press out the fiber to squeeze the last bit of liquid from it and discard.    7. Save the three combined extractions in the 1-gallon container. Allow the vegetable particles in the extraction in the 1-gallon container to settle to the bottom overnight. Then pour off the liquid into an empty 1-Gallon GLASS wine jug, being careful not   to pour off any of the vegetable sludge at the bottom.     8. Discard the sludge and keep the contents of the wine jug.       [b:c53be868fa]Here is another similar to where I am today...[/b:c53be868fa]      OK here's how swim does it inabout 7 hours.we will be doing a 375 gram MHRB extraction here.(which should yield between 3 or 4 grams of spice.   1. Chop up the rootbark using a paper guillotine to save time- about 15 minutes   2. Pulverize it with a blender bit by bit - about15-20 minutes depending on your blender.   3. While youre doing this you are preheating your crockpot with 2 and a half litres of water   4. Add vinegar and stir and check PH with digital PH meter it should go as far down as about 3.if it is higher add some more vinegar,stir it up real good and re-check PH.  5. When your PH is around 3 add the rootbark powder and stir the shit out of it.  6. Let it simmer for three hours stirring the shit out of it often.  7. When two and a half hours have passed stop stirring to let the guck settle to the bottom.   with the chopping and grinding and simmering we are now at 3 and a half hours.  8. Pour the liquid through a cheese cloth into a wide mouthed stainless steel or glass(punch bowl will work) type of container.  9. Close up the cloth over the plant matter and sqweeze the shit out of it to get all the juice out.It's very hot so wear dishwashing gloves.whet you feel it too hot even with gloves pass your hands with gloves under running cold water and repeat the sqweezing till it's almost a dry pulp.this takes about 5 minutes.you now have a bowl full of a purplish reddish liquid that looks like cheap red wine.      And yet a third...    http://www.geocities.com/aerondir5meo/guide_2.pdf      Sorry Trip for the data overload...    The three <teks> essentially said the same thing so I followed them. I had to intially guess at the PH on the first extraction (hmm, 5% white vinegar plus equal volume water equals 2.5% acid solution). I later found an aquarium PH test kit and verified.    I don't know if this will work. You got crystals yes?????    Speak up support team! Are we off (free) base!
