Goat reply start: Actually, there is no gas in a crt tube, they are evacuated at vacuum and the tit or neck where it meets the body (can't remember which now, as it has been a while since I looked into buying the equipment to rebuild picture tubes, and researched exactly how it was done), is melted shut. That is why when you break the tit off the end, you can hear the hiss of inrushing air. There is no reason to break the glass of the tube at all, if there is concern for some. It is certainly best done in some sort of enclosure, which is why I suggested breaking the first ones in the cases to begin with till one gets a hang of what to expect. The best means of doing the job if one doesn't want to do the job as recommended in the service industry by disassemble till you can get to the tit and break it off, is to smack the neck towards the end, and it usually snaps off toward the body of the tube, or "shatters" (it will break and be sucked into the tube mostly, from the inrush of air). I've done hundreds of them this way, or the other way as described by breaking the tit off, even many more then when I just used the "brute" force method. Once they are evacuated, and stripped, then I have as well then broke then down towards the face of the crt to make them more compact for disposal. "The cathode ray tube (CRT) is an evacuated glass envelope containing an electron gun (a source of electrons) and a fluorescent screen, usually with internal or external means to accelerate and deflect the electrons. When electrons strike the fluorescent screen, light is emitted." http://en.wikipedia.org/wiki/Cathode_ray_tube I certainly though would try to avoid sniffing the coating on the face of the crt that is used to make the "picture," if one chooses the brute force method of breaking the tube to the face, though it clings together rather robustly and isn't to prong to dust. There is probably some values in that (the coating) as well, but it would be very had to collect in quantity to make it pay, unless you were doing a very lot of them. Yes, there is all sorts of sites on the net explaining how to build a melt furnace, and I have built some of them myself. Please though, any input you have would be appreciated. A better place to discuss the matter might be on the blog (if it wasn't you who already posted something there already, but it really doesn't look like the same style or concerns), so that I don't miss it, and that all the discussing is in one place, and nice and tidy for reference, though certainly what we committee on the subject should be of concern for us all, including the world over, as it is a solution for not just here in the us, as it might well help those in other places that are in the grip of the "beast." Such is one of the main reasons that I posted it here, as I know others in other parts of the world who are interested in a return to hard metals may also have overlooked copper, while looking only at putting the main burden on silver and gold. A good furnace as you indicate is also I nice addition to any shop, and tooling up is a goal we should all keep in mind, since most our industries have gone elsewhere, and we need to start to rebuild them. Such rudimentary industrial processes is essential to start regain if we are ever to start to find our way out of the morose we find ourselves, if the ptb will allow us, as they have went to a lot of trouble to bring us to a the point we are now, so a keep your head down approach may be best, as far as doing, unless one feels they are in an area that is fairly libertarian. Here is the addy for quick reference and input (non constructive, and especially anonymous such, will be deleted, constructive will be retained and incorporated in the main blog, as will material posted to email). http://social.infowars.com/blog.php?user=Goat I'm not sure were you are going exactly with the lead part, though I will assume that you are saying that the lead glass may also have some value? If that is the case, then it would certainly be worth looking into for those who wish to do this in mass, rather then just find away to dispose of the leftovers when happened on an occasional opportunity. I certainly agree with the rest of your post. If China is now forced to start mining raw materials (or acquire them more so), then it means that it would take that much less to have some effect we are seeking.
