approximatly one year ago, all wholesale pyro chem suppliers in the u.s., were paid a visit by the d.e.a., all records of rp sales were seized. also, pyro guys often mix their chems. oxidizers like potassium percolate are mixed with 600 mesh aluminum for flash powder. wood meal is used for a filler in aireal outdoor applications. my point being, if you find rp in something, it is probably mixed with something else, and extraction attempts without some pyrotechnic chem knowledge could bee fatal. if you still feel like messing with it, at least spray static- gaurd on yourself, spray static-gaurd on a news paper, and do your work there.
