No offense taken, Jason. I haven't tried to brew up any concoction and I
don't plan to. Sandblasting is tempting, but there again I'm worried
about inhaling the dust. The $100 it saves now (or whatever the price
is) would be chump change in 10 or 20 years when I just want to breathe.
I quit smoking 3 1/2 years ago and my body is recovering very well. No
sense in wrecking it all over again. I do enough hobbying around nasty
stuff without adding chromium to the list. I find myself wearing a good
quality *dust* mask more and more often.

OK, let me step in here at this point. Someone may have already mentioned this but chromium can be very, very toxic. Cr(III) (trivalent, or chromium 3+) is not too bad, but Cr (VI) (hexavalent) is a known, proven carcinogen (primarly giving lung cancer). OSHA page: www.osha.gov/SLTC/hexavalentchromium/ It will mess you up, and it will mess up the environment if you pour it down the drain. Heck, you can put your local sewer treatment facility out of business for awhile if you flush enough of it. Cr(VI) is mobile in the groundwater, so if you bury it, it just moves to your neighbors land. You will be financially liable for remediation costs. It's easy to accidentally ingest, either by breathing it or swallowing it (If it gets on your cigarettes or you hands). Bottom line: Let the pro's do it- they have the equipment, and they can give it to waste disposal and treatment facilities. Trust me on this, I'm a University Chemistry professor. I don't want to see anyone hurt or sickened. Greg- this isn't aimed at you personally- I'm using the general 'you'. J Greg Bender wrote:
