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.

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.

Yes, I was going to say CrO isn't a simple substance. it comes in many different varieties each with it's own characteristics and it also comes with other things mixed in. lapidary shops sell it in large bars but it contains other products great for rock polishing but bad for razors and it doesn't say what those extras are often times.
