Thread: Chromium Oxide

Hi gents,

I live in the UK and am trying to purchase some Chromium Oxide green paste that I can use to carry out the final polish of my straight edge.I will either apply it to a strop or balsa wood paddle. Do you guys know anywhere where I can purchase the product as I am having problems finding a supplier.

Secondly, have you any other suggestions on what I should use other than the Chromium Oxide for a final polish. I have a coticle and diamond pasted paddles,its just the final edge that I am hoping to improve on.

Regards

I have found that you can buy it for about $12 a pound at various rock pollishing web stores.

Hello!

I just wanted to add my two cents here...

Of course, you can find it there... BUT... what one knows about trully is inside? Dye? Chemicals?

You name it....

Then, the question to ask yourself is about the granulometry....

The next one is... Have someone you know tried it?

To answer to Dave, I would definitively recommand him my red paste... which with my green, are giving a more confortable shave than one can have with diamond pastes. (Go in the "Classified")

I am surely a little more expensive, because I am providing a service as well along with it, but definitively less expansive than a Japanese 10'000 or 30'000 chinese/japanese stone.

BBS yours,

Valentin

The reality of using chromium oxide .5 micron powder for our purposes (final polish of razor edges and maintaining edges) is that the powder goes such a long way, the amount the size of a large almond could last someone a year or two if they use it to apply to a strop or two and also put some on newspaper for stropping. Seriously. A pound of chromium oxide .5 micron powder in volume would be about the size of a tennis ball or more. My point is, much much more than anyone would ever need for our purposes.

The other point that is rarely brought up is that the chromium oxide we use is quite hygroscopic ("the ability of a substance to attract water molecules from the surrounding environment through either absorption or adsorption")
The wiki definition.

That could be bad for stropping delicate edges on what used to be powder but after being stored improperly for potentially years, could end up being unfriendly hard gritty chunks, etc.

If someone gets into restoring blades and has a vibratory tumbler, I think larger quantities of chromium oxide make more sense. Even then going through a pound of it when only a little bit would be needed to refresh the polishing media would take quite a long time.

Don't get me wrong, the stuff wouldn't be hurting anything if someone buys way more than they'd need, but I'm just saying be sure to make room on your shelf!

At least one I found lists it as sorted to .5 micron.

Oh I was aware of that, it is just that I was currious and looking for web sources as hand american seems to be down.

So I was trying to figure out where I could actualy get some.

Would baking it clear that up? It does for some other highly hydro scopic things.

I understand completely.

I guess it's possible. I have had no reason to try this however.

Thinking it might work, but you might still need to mechanicaly break up the clump, and I don't know if normal honeing would do that.

When maxing powder with water do the clumps stay or disolve?
