Letting naphtha+basified mixture sit for months...

Does anyone have any experience with this? The last time I did an extraction, I never siphoned/decanted the last pull (I think it was my third). I just left the milk jug containing naphtha/lye/bark out in the shop for several months, somewhat forgetting about it (after trying my first batch, I felt little need to exhume any more spice for awhile).

Seeing it today and feeling curious, I separated the naphtha layer and it's in the freezer now.

Any known reasons as to why this might be a bad idea? Just curious. Tried to find a similiar post but I'm not having much luck.
 
I cant see any reason for it to be "bad" it will simply be more difficult.
The spice oxidizes over time and since the solvent has been sitting with the solution for a very long time you will end up pulling a TON of oils from the bark. Chances are you will end up with non crystal forming goo.

I would read up and the conversion of oxidized spice back to normal spice and prepare for a nasty couple of recrystallization before you come up with quality spice again.

There are also allot of talk about it breaking down over time in a high ph solution so it is possible you will get nothing useful out of it although that seems to be more conjecture then fact still.
 
Nope, I do this every extraction.

After I can't get any more spice out of my naphtha pulls, I will stick 200mL of naphtha in the basified jug and let it sit a month or so.

Freeze solvent, add toulene to basified jug, let sit another month.


Spice comes out just fine.

I wouldn't want to do this for my first 2-3 pulls, only when the spice concentration starts getting really low.
