Seanattikus Posted January 18, 2008 Share Posted January 18, 2008 I'm trying to get some rust for making thermite through electrolysis. I've got it set up and working with a screw on the bubbly wire and some stuff is building up at the bottom of the jar and on the screw. The only problem is that it's not red or orange like I expected; it's light blue! Does anyone know what this could be? I'd appreciate any information you have on this. Maybe I've got the wrong wire or my screw isn't iron. Also, is this stuff safe to handle? Thanks for your help, Sean Link to comment Share on other sites More sharing options...
insane_alien Posted January 18, 2008 Share Posted January 18, 2008 you have bare copper in the electrolyte don't you? Link to comment Share on other sites More sharing options...
Seanattikus Posted January 18, 2008 Author Share Posted January 18, 2008 does the wire count? Link to comment Share on other sites More sharing options...
YT2095 Posted January 18, 2008 Share Posted January 18, 2008 if it`s Copper and in contact with the electrolyte YES! Link to comment Share on other sites More sharing options...
Seanattikus Posted January 18, 2008 Author Share Posted January 18, 2008 how am I supposed to get around that? use iron wire?? the blue stuff formed around the screw, does that suggest that the screw might have copper in it? I just looked at it more closely, you're absolutely right. The copper wire that wasn't bubbling as much is gone and the flow of energy has, therefore, ceased. So it was that wire that made all the blue stuff (Copper Oxide?). I'll just have to get different wire I guess. Link to comment Share on other sites More sharing options...
YT2095 Posted January 18, 2008 Share Posted January 18, 2008 OR, still use copper but longer electrodes so the splashes from the bubbles that pop don`t attack the copper and make the soln drip down. you can also tape up or better Wax cot the junction.

Mr Skeptic Posted January 18, 2008 Share Posted January 18, 2008 You don't need to do electrolysis to get rust. Just scrape some off the bottom of my car... or grind some iron nails to a powder, or put some steel wool in a jar of water. The non-oxidized aluminum will be harder, as it will oxidize on contact with air. Link to comment Share on other sites More sharing options...
insane_alien Posted January 18, 2008 Share Posted January 18, 2008 the fact he doesn't understand the principles of electrolysis suggests to me he is not at the level where it would be a good desicion to make thermite. Link to comment Share on other sites More sharing options...

ROFLOL, I`m glad YOU said that, If I had said it, I`d be seen as "Picking on" people AGAIN! Link to comment Share on other sites More sharing options...
Gilded Posted January 18, 2008 Share Posted January 18, 2008 Making thermite is always a good decision. Aluminum-iron oxide thermite is probably one of the safest pyrotechnic mixtures. In amounts of several kilograms it's kind of scary though. Link to comment Share on other sites More sharing options...
Seanattikus Posted January 18, 2008 Author Share Posted January 18, 2008 I do still have a lot to learn about these things, and that's why I'm asking you. I now know a bit more about electrolysis and I'm going to be studying it all night now that I realize how little I do know. I don't see, though, why I shouldn't be trying to make thermite. I know how to deal with hot things, you just have to make sure to not get close to them. Once I've made the stuff I plan on rigging some way to light it from a distance. Also, I know I could just scrape it off something but I'd rather use electrolysis and learn about it then get a sore arm. Link to comment Share on other sites More sharing options...
insane_alien Posted January 18, 2008 Share Posted January 18, 2008 i've seen badly made thermite shoot gobs of molten iron 10m or so. it can be extremely dangerous as those will burn through you. there is also the danger of setting fire to everything near it. besides, thermite is really boring anyway. it doesn't actually do anything interesting. i'm currently into the silicon analogues of various hydrocarbons. i've managed to produce and contain silane and possibly disilane though not in large enough quantities to be sure of. Sulphur hexa fluoride is another good one to make. can make your voice really deep if you inhale some of it(it is inert in the body, watch out as it displaces oxygen so take a few deep breaths between inhalations.)

Mr Skeptic Posted January 21, 2008 Share Posted January 21, 2008 the fact he doesn't understand the principles of electrolysis suggests to me he is not at the level where it would be a good desicion to make thermite. Good point I should be a little more observant. The fact that he thinks he knows how to deal with "hot things" probably is even worse. 4500 degrees F and melting through metal is probably hotter than most things he has dealt with. Seanattikus, may I recommend you read some of the dangers of thermite before using it? Link to comment Share on other sites More sharing options...
insane_alien Posted January 21, 2008 Share Posted January 21, 2008 yeah, and you know something can go really wrong when i'm the voice of reason. and as for dealling with hot stuff, how often have you dealt with somthing at 2500*C that is going to stay that hot till it's over? its not as if you can just chuck some water over it to stop it, it'll still keep going, explode in your face and continue reacting in side you. neither will a CO2 fire extinguisher work(probably speed the whole thing up) and, well, any of them would be utterly useless at stopping the reaction, most would make it do something incredibly violent.

YT2095 Posted January 21, 2008 Share Posted January 21, 2008 a welders mask with the green tinted glass is a good idea too, Thermit gives off a Lot of IR light that is damaging to the eyes and you wouldn`t even know it was happening until the damage was done.

insane_alien Posted January 21, 2008 Share Posted January 21, 2008 yeah, but its mainly the UV light you need to worry about. it will do more damager than the IR. Link to comment Share on other sites More sharing options...
YT2095 Posted January 21, 2008 Share Posted January 21, 2008 yeah the UV`s killer too, IR`s very bad though! esp is Sand is used, many Glass blowers will tell you this. Link to comment Share on other sites More sharing options...
