Thread: CrOx MSDS... Hmmm

I just Googled the msds for chromium oxide for fun. Didn't know it contained hexavalent chromium. I guess I am not drinking it, but it can get worked into your skin quite a bit, especially when applying/working it into a strop.

You can use gloves ... Did you know that stuff is used as pigment in green paint?

... actually I managed to get it here very cheap as a green color pigment !

Just don't lick you fingers when applying.

It is all about consistent partial size, Kremer pigments has very good Chrome and ferrous Oxides at reasonable prices and quick shipping. A little goes a long, long way.

There was recently a similar thread here re Kremer and which pigments were recommended.

"A little goes a long, long way." ... when you spill some!

Chromium is a classic allergenic, some develop an allergy after some time, so try and keep it off your skin.

Also any particles this small will be bad for your lungs.

Yes, wear a mask when mixing.

Haha, I don't think we need to take it to that but at least know not to play around with it.
If you did it as your job you probably would need to use a mask and all kinds of protection.

I keep a box of paper masks on the bench for playing with powders, grinding and light buffing. In younger years I did a lot that I probably should have had more protection and got lucky.

Now I buy a paper mask and safety glasses in quantity and keep handy. It takes but a second to loop a mask over your ears and slip on a pair of glasses.

Green: Chromium III oxide: Chromium(III) oxide - Wikipedia, the free encyclopedia

Purple/Red: Chromium VI oxide: Chromium trioxide - Wikipedia, the free encyclopedia

Hexavalent Chromium (Chromium VI) is the toxic one.
