I reduced my extract of nightcap down to 10% and mixed in some pg but it looks really opaque and dark. Is this the norm or have i ruined it as i saw bubbling during the heating using a double boiler.
Opaque and black as "day old stale coffee" is the normal color/appearance for a reduced extract of Dunhill Nightcap. You should be fine.
Once you mix the extract with the appropriate ratio of PG, VG and liquid nic it'll be translucent and lighter in color.

Has anyone ever done a cold extraction with PGA? Just curious to see how it may turn out.
Yep, soak between 96 - 120 hours at room temperature, tastes great but lacks some of the darker notes that heat provides IMHO.
Thanks. I am going to try this and compare the results with heat. Will update when done.

did a "freezer" PGA extract, let it steep for 5 weeks ( put it in the freezer and forgot about it then the wifey went to move stuff and found it)... very light tasting as compared to a heated extract.
What kind of tobacco? Was is light in comparison with same tobacco done at room temp?

To bring back a subject that has already been discussed, I find that my extracts always leave a waxy residue on the walls of the plastic bottles they are stored in. Is that an indication that I missed something in the freezing/filtering process? Seems odd since I underwent a lengthy freezing process beyond normal. Does filtering have anything to do with removing waxy oils? Unless I am wrong, I always assumed filtering was just for removing tiny particles of tobacco - not oil.
Some tobacco contains more oils than do others. For those the freeze filtering doesn't remove all the oil, I've had a few like that. Regular filtering only removes the particulates, not oils.
In that case dry ice may help. The only concern is cracking of plastic or glass from the intense cold.

Or wooden ones !! Believe it or not, I do have the metal in stock somewhere. Just have to find it...metal shot glasses...

it was a Mc Clellands 3 cherry... did a freezer version and a heated version.. heated version had more deeper tones to it, more tobacco forward as to where the freezer version was more cherry, less tobacco. The freezer version was much clearer ( transparent) compared to the heated.
It might. The question being will it separate/remove oil that is well dissolved in a solution or just oil that has separated out of the solution and exists in a free state, like a "skim" that forms on the surface. I wonder how "thick" the filter material is, how much extract will it absorb and hold? Would it substantially increase the amount of extract we lose to the filtering process? Polypropylene is compatible with the solvents we use for extraction but what binders/chemicals are present in the material that might make it into the filtered solvent? Are these filter's retention ratings absolute, or nominal like filter felt? I believe they're "nominally" rated (up to 95% efficient), so would opt for the 1 micron. If not too expensive I would certainly try one just to see. Good find.
I would love to give this a try if the fabric was available somewhere. The assembly as shown has too large a capacity for our application. It might be too thick as well.Is there somewhere you could see the material?
I bought a 1 micron fabric from Amazon, and the material is nearly 1/8" thick. Will probably absorb a lot of the extract.
I wonder if tobacco oil is some rare luxury item that costs a fortune to make.... and here we are throwing it away
