Hello Guys,
it's a pleasure to ear your comments, thank you very much.
We know more or less where we lost goodies, and the 2nd manske (not enough room for liquids) was it,well our filtering tek too, loss some mL each filter (above 25filter & 30 cotton ball used)
We have a buchner funnel but we clogged it in our final filtering stage, it have a ceramic or cellite filter, but very small (15/40 microns). Actually acetic acid is on to dissolve. It work nearly normally with acetic but when it's water, filtering is harder. I choosed this cheap one for the pump ^^, Does a Lye solution can help cleaning ?
Our paper filter are chinese and we can't read the size of holes.
As said, Tao of Rue really teached us, and we learned a lot.
In terms of taste, i tasted a bit of extract on my tongue (maybe 1 or 2 mg) and i noticed no taste or a very little bit of "i don't know what" and a bit os basic feelings (like sodium bicarbonate ), but this test has been done at woke up before cofee ^^. During cooking, the smell of rue isn't bad and unpleasant, we found this plant really cool to work with, according to the tao of rue or in incence. The standard use of no or very little harmfull chemicals is very great (for our earth and us). We have passiflora as local source of MAOI, and actually didn't find one more documented / tested
With your messages and observation we're really confident on the final product and will test it on it's own, there after with another extract. We're confident too for the MAOI diet, as from this new year, junk food is reduced to it's minimum, alcool is consumed maybe one or twice a month in small quantities, no medication, and we used to feast above once a week. This permitted to us to live very different kind of psychedelics experience (compared 10 years ago), no eat during one day or two can be handled without noticeable impact on being tired and social life (just a big hungry after :lol: ). We heard too that harmalas seems to be safer than other MAOI in terms of diet.
We'll plan to make a changa with 300mg harmalas, 1g acacia simplex extract,450mg damiana, 450mg passiflora edulis dried leaves, 100mg peppermint,
Our solution before 2nd manske was pretty clean looking too :

As we collected all the rinse solution we could later continue our test & saw additionnal yield.
After the 1st manske, le resulting filtered solution has been reduced, added a bit of salt, and go to the fridge, but didn't saw any precipitate.
For the 2nd manske it hasn't been done due to no more space / equipment lab (that's an error), here the 2nd manske with no room :

I like this basic splash onto harmine precip.

We'll not plan to do lab analysis on this extract, as it's a pretty common plant, and i trust in your visual analysis. This extract could be named "Red Harmalas" ?
Last pic with comparison with end solution (on the left at 5th water wash) and the washed extract of the first basing step (on the right 5th water wash)

Cheers all
