Have you extracted off the same batch of bark, if so does this reflect similar yield?
How long, how many boils? I'm familiar with EWs tek- 3/45 minute boils, yeah?
Maybe some experiments are in order.
First off ..I used only 100grams ofaccia bark expecting no more than a little over one gram of product...
i ground the bark fairly fine.. then i tryed just adding a little salt and boiled the ground bark in filtered drinking water then i used a two speed kitchen ..[turbo blender].. in the pot of boiling bark.. [as it was boiling]..several times which further pulverized the bark to a much finer texture..
I think its simply the heat and water and the fine choping action of high speed blender thats superior to just stirring the mixture with spoon...the salt may have had a minor acid effect?
I wasnt shure it would work without freez thawing and using a light acid.. but it worked fine for me..
I noticed the diference by comparing the..[ water and salt extraction] and the water salt and vinegar extraction] i had in two equal containers..
The first bottle [using water and salt] almost all the goddies were removed from the bark i could see a darker thicker color in it..
I then re boiled the bark for the second bottle using [vinegar water plus salt].. and it came out lighter in color and after basifying and removing the napatha it produced only about one third of the total crystals compaired to the water and salt only boiled bark..
Simply put.. only boiling about 90 minutes ..the first boiling using ...water and a little salt.. took most the goodies all out of the bark compaired to the second acid boil this process removed most of it quickly without using the stinky vinegar..
Heat and superior agitation works fine without freeze thawing and using acids..
I just figured that the natives in south america boil out the goodies using water bark leaves and stirr it for hours in their ceramonies and it works fine..
