Caleb51 Posted March 25, 2006 Posted March 25, 2006 Hello. I tried making rust by putting some steel wool in a container full of water, bleach, and vinegar (as told to do by a website on how to make thermite) and then I took the steel out, put some paper coffee filters in a strainer to keep the rust in, poured the rusty water through the strainer, and receieved a paper filter jam packed with rusty water no longer able to pass through the filter. I put all of this in a plastic tupperware thing and left it in the sun to hopefully evaporate the water and be left with rust. Will this even work? Any better ideas?
aquaman Posted March 25, 2006 Posted March 25, 2006 Try this insted Iron oxide. If you have any questions teknix could probably answer them.

Put it in a larger container (transparent if you can) and add more water to help dilute the excess bleach, and just leave it undisturbed for a while, preferably elevated above the ground. After a few hrs, the rust will have settled to the bottom of your container and you can use some tubing to siphon the water off (the reason for elevating). You probably want to repeat the washing/siphoning step a few more times to help wash the bleach from your product. Pour the sludge out in a shallow, glass, baking dish to help facilitate drying. You could even pop it in the oven @ 250F for a while to dry it out faster. Or, you can just go to your local hardware store, purchase iron oxide concrete pigment, and save yourself the hassle.
Caleb51 Posted March 26, 2006 Author Posted March 26, 2006 lol, I'll try that siphoning thing. Do they really sell Iron oxide pigment? I looked, but found none....
FrankRizzo Posted March 26, 2006 Posted March 26, 2006 lol, I'll try that siphoning thing. Do they really sell Iron oxide pigment? I looked, but found none....Yeah, they sure do. Look in the paint/pigment area or the building materials section (near the concrete) of most major home improvement stores. Usually there are two different types, liquid and powder. You want the powder...red.
pa_pyro Posted June 29, 2006 Posted June 29, 2006 For iron oxide I use 3% h2o2. (sorry i dont have exact measurements) I take the desired amount of steel wool and place it in a small container and just barely cover it in hydrogen peroxide. Then I add some salt and a pinch of yeast(catalyst). After it's done reacting I pour off the liquid in a seperate container and repeat about 3 more times. After most of the steal wool has been converted to rust let the water evaporate and you should be left with a fair amount of rust. Sure beats chlorine fumes (just tested it earlier today)
Swany Posted June 30, 2006 Posted June 30, 2006 Which process are you referring to that produces chlorine? Dissolving steel wool in HCl produces hydrogen and Fe (II) chloride, which is oxidised to Fe (III) chloride by air, hydrolysis may give Fe hydroxides, though after adding a alkali hydroxide you get the alkali chloride and Fe hydroxide as a ppt.
Mumbles Posted July 1, 2006 Posted July 1, 2006 He's talking about one of two things. Either the proceedure where acetic acid(vinegar conc) and bleach are mixed with steel wool. I am not positive this produces chlorine, but there is a very strong smell eminating that could possibly be HCl. More than likely it is a mixture. More probably he is refering to electrolosis in a NaCl soln.

Thats pretty much what I do except for the siphoning part. I just decant most of the water[60-80% is pretty good]. To drive off the rest of the water I use a BBQ grill[any other heat source works out too].
