Any results as of yet Terraphon? I am quite interested in this.
GAH!
I meant to post the results in here and I totally forgot.
Here's what I came up with.
Copper content was < 1 ppm (some indication of detection in the .5 ppm range but the reagents I use are meant to be used on water, not nicotine and oils so I'm NOT sure of their efficacy).
I also ran rudimentary oxidation tests with Sulfuric, Sulfamic and Hydrochloric acids and was unable to create a reaction...That is to say that I was unable to get the solution to turn green even at 1:1 juice : HCl. I'd say that rules out the oxidation theory.
I'd like to perform pH / alkalinity / dissolved solids tests but I don't have a big enough sample. I could do dilution tests but I can't be arsed to bother with the math.
Verdict : I don't know. I know that the oxidation theory is shot to hell and I don't think it's a copper issue (damned good thing, too...Copper toxicity ain't pretty). I'm still not apt to put the stuff in my body after the things I've seen.
I'm doing a series of reviews on JC liquids right now and will be going through about 1 ml of several of them (actually vaping up about .1 ml or so) and then I'm done with their crap until they sort themselves out.
The unknown is, for me, too risky.
