Oh nice, exciting developments since my last visit to this thread 
--
I decided yesterday that it was time for me to do a CIELO again.
This time, i did everything as simple as i could, no extras. I don't have too much time for extractions atm, so i went a little bigger.
If i was going to get goo, i was going to just dry it and consume it as is - last time, I had failed horribly trying to convert it to sulfate.
I made a paste with ca. 360g dried pachanoi powder, 85g CaOH and 875ml water. I mixed the CaOH and water on the magnetic stirrer, then used a kitchen machine to mix the suspension into the cactus for a few minutes. I let the paste sit for about 30 minutes, then gave it another few minutes of mixing.
I pulled with a strict 1min stirring / 2min sitting regimen. I used the same EA from summer that i extracted with twice already. I had washed it in the meantime. Due to my choice of vessel, i couldn't add very much EA at once. I did close ca. 10 pulls and ended up with 1L of dark green but clean loaded EA. I let it sit for 20min to see if any kind of droplets were forming, and they weren't 
I did the quick precipitation method. Because i had 1L of EA, i added 15g of citric while mag stirring. After the cloud disappeared, i removed the stir bar and let the precipitation sit over night.
In the morning, i poured it through a coffee filter and washed twice in the filter with fresh EA. I then folded kitchen paper around the filter and squeezed as much trapped solvent out as i could. I opened the filter, loosened up some 'rocks' of mesc citrate and laid the filter on it's side to air dry.
2h later, i had 3g of dry mesc citrate powder (see pic) 
I'll let the filtered EA sit for a few days/weeks, in case some more wants to crystallize slowly.
