ok ill crarify the method. get dilute salt slution, dip in 2 iron electrodes, hook them up to dc current. mine was 30 volts adapter. id run that for a few hours, the bucket would be full of stuff floating around. id poaur the stuff in a cup, then let it settle, then pour off the execc, and repeat. after a while i had like a cup of the gunk still in water. id set that under a lamp for a day or two, and id get a good amount. after u dry it its like brow, but after u heat it in a dish its nice and red.
ps: my crappy avatar is an example of my iron oxide
