I've considered talking more abut the process, but after past discussions with some of the more technical folks around here (Kurt, for example), it always comes back to the specialization of a number of the steps and the background to perform them safely.
DVap: I completely respect your decisions in that respect (ha, that's almost poetic). I do have an extensive background in experimental chemistry. I worked for 20 years as a lab technician and chemist in industrial chemicals R&D. Worked with all of the most nasty and dangerous chemicals and processes at some point. But, alas, that was more than 10 years ago. I'm into electronics now.
It is not my intention to try and duplicate your work or try any even potentially dangerous recipes in my basement. I do know enough to know what's safe and what is not. I have no lab and no equipment and not even the time to spend if I did.
My interest is purely curiosity. I just love chemistry and really miss it sometimes. I thought maybe you had already given details somewhere. I haven't had time to read any significant portion of all the posts on this subject. I was really pleasantly surprised to find vapers doing CHEMISTRY when I joined the forum. Made me a little jealous to tell the truth.
At this point I'm content to try some very simple (anyone can do) kind of extractions that would produce a vapable mix that substitutes for smoking. I really think I may try the espresso machine which I've had sitting in a box for a couple of years now. Eventually I need to take the time to figure out what to do with all the rolling tobacco I have stashed away or maybe I'll just keep it for a "rainy day".
I haven't completely quit smoking and may not unless I find a better substitute but I am really amazed to be smoking only three or four analogs a day after being an addict for 40 years. I found it so easy to switch to vaping and i believe I could quit completely if i wanted to as vaping IS good enough and in some ways much better. I really enjoy being able to puff away to my hearts content and in places where I used to have to grit my teeth and wait. I FEEL LIBERATED BY MY PV!!!
Sorry to go on and on. I don't usually spend this much time punching keys and probably won't again.
I sure appreciate everyones efforts to develop this whole subject. I don't have time to follow all the threads so forgive me if I ask already answered questions.
For instance, what really is the composition of the vapor produced by the atomizer? How can it be "water vapor" like the ads say unless the heat decomposes the PG/VG to CO2 and water? That just doesn't seem likely to me. And how long can I store a 48mg nicotine solution at refrig temps before it starts to degrade significantly?
