Canabineer, most of your questions seem to come from a lack of careful reading. Normally, I'd be happy to spend all day enlightening you, but since youve taken an antagonistic tone, I'll just give you one response right now to this one post, and I would encourage you to reread with more care, and the understanding that I didnt use superfluous words. No, I mean flash point - "The flash point of a volatile material is the lowest temperature at which it can vaporize to form an ignitable mixture in air" - wiki. flash point is important to consider when adding a solvent into a hot mix, if it reaches its flash point, it will evap off before getting mixed in, all in a poof. Which is why you cant cook as easily with a limonene tincture. They are hardly tiny, benzene is a basic carbon compound and most of whats generated is carbon soot, of which benzene is a large component. And as I stated, once or twice likely wouldnt hurt you, but repeated exposure to soot (like in those who grill meat for every meal or in chimney sweeps) has been proven to cause carcinomas. That temp was given by the bic website as the average temp of their lighters flame. But lets say you're right and the way too low 1000 degree is the right temp (heres a hint as to why thats low: a flame is plasma, which means the temp has to be high enough to ionize the air and form a plasma jet for you to have a visible flame, and air ionizes at above 1000 degrees), in any event 1000 degrees is far beyong the temp of combustion for the cannabinoids, which is the point I was making I did specify - things exposed to heats higher than their combustion temp break down into non psychoactive substances as well as carbon soot, including benzene (and carbon monoxide, and a whole spectrum of others) You should, that was just a rough estimate, based on the amount of benzene in soot avg, and the amount of cannabinoid oils Ive been able to recover from my experiments with resin. I absolutely encourage you to find more specific values, and I will replace them. I know a cheap lab if you want to have your resin tested for the cause of furthering science. Carbon is absolutely soluble in water, it is highly soluble in fact. Which is why I said itd migrate to the water in a xylene/water purification, leaving the cannabinoids in the xylene. lol I've never been accused of being chemophobic before. What part of my detailed explanations about isomerizations, isolations, and novel chemistry fun gave that impression? Sigh personal attacks - the resort of those who dont have a leg to argue on. Well, lets say I used too much hyperbole, and that you are correct, its only in the middle of carcinogenesis - why the problem? All I did was say it was fine exposing yourself once or twice, but that repeated prolonged exposure would increase the rate of carcinomas... something that is correct in either case. Yes, grilled meat has nitrosamines, form from the nitrogen compounds. But that doesnt mean its the only chemicals present. In fact there is an elevated amount of benzene, bc thats just whats formed when you burn carbonaceous compounds, which is why that comparison is relevant - long term exposure to elevated levels of benzene elevates the incidence of cancer. Which is the point I was trying to make, and I must confess confusion as to why you would try so hard to repudiate it Yes, it is. Which why I said it dissolves in butane and more poorly in xylene. It dissolves more efficiently in water than in xylene, and less efficiently than cannabinoids do in xylene, which is why if you to the xylene/water purification, after a lot of work (too much work to be worth it), eventually the benzene will migrate completely out. Which I already explained - again, read more carefully, make sure you understand the concepts involved, and then decide if its wrong or not, not the other way round lol. You say its not correctly presented, well, you are more than welcome to do a "correct presentation" writeup and post it. I would love to see someone who has more time write up these concepts in their absolute minutia. However, based on your questions, its not so much that I got the chemistry wrong, its just that you didnt read or comprehend all the chemistry. So yeah, since you clearly didnt bother reading this carefully, as most of your questions are based on either skipping portions or not understanding them, and since you've already decided Im wrong and will likely just keep arguing, trying to take down my logic with semantics, all without offering any actual data which might counter my claims, I'm afraid this is the last time I will be responding to you in this thread. If you have some non antagonistic questions and are just trying to learn, I will be happy to help if I can in another thread, but if insist upon continuing the internet style of arguing ("No, youre wrong! I only skimmed what you wrote, have neither data nor logic to back up my claims, but have decided you're wrong either way!), I'll just block you so I wont be bothered with it. I am, after all, only here to share to neat tricks I've learned. I don't care enough to push them upon people who don't want to listen. Speaking of which, for everyone else: I'm compilling my medible recipes, and some other neat tricks not seen anywhere else. I think you'll like them; Ill start a new thread when I do. Thanks for all the rep everyone, I really appreciate it. If you've liked my posts you should check out the thread in my sig. Its a long read, but is well organized and in chapters, so you can skip to the parts that interest you; its an overview of concentrates and all the major vaping options on the market, as well as plenty of tricks and tips, all presented in the same, methodical style. Give it a look, it dispells a lot of the myths around concentrates and their tools, and will give you a clear understanding of the concepts as a whole.
