I sent an inquiry about particle size to Kremer, and just got back a reply, which I will add below. They say "predominant size is 0.3 microns", and I gather it is very pure, meaning not many particles of other sizes. Attaching their spec sheet.
I'm going to paint some balsa, and start using it in order to compare to the CrO paste I'm using now from Straight Razor Designs.
KREMER RESPONSE
The predominant particle size (μm) is approx. 0.3. I attached the scientific analysis .pdf file for your own research. If you have any further questions or concerns, do not hesitate to ask.

Will test, and will reply here. I have asked for more specific information about the % of larger particles, and will respond here also if I get more information.

Thanked: 402I use the Kremer all the time and it does the trick beautifully.
Thanks for testing though.

Olivia, have you used other Chromium Oxide sources other than Kremer? If so, how would you compare?

Thanked: 402No I haven't, Larry!
I buy their pigments for years, so I had no demand.

Those pigments work beautifully, they are excellent.
There Cr2O3 is excellent for finishing razors.
There is however another very interesting pigment I would like you to try,
if you decide to buy from kremer.
It is
PR 110 M hell
That is red iron oxide (Fe2O3) with a given particle size of 0.09µm
I tried it and I love it. Extremeley fine, a little finer than their chroimium oxide.
Defenetly nothing you need, but makes for the smoothest and sharpest shaves.
I love Kremer (and it´s so cheap...)

Thanks for the information about FeOxide. At 0.1 micron, I didn't realize it was so fine! And, I will try it.
I am doing well with CrOxide as my last polish, (0.5 from SRDesigns and 0.3 from Kremer.) However, who is ever satisfied?
I ordered some 0.25 micron diamond spray from SRDesigns, and it should arrive any day. I will try it as my final polish. But, the one complaint I hear about using diamond as the final polish is that it leaves a more gouged, harsh bevel and edge. Sharp! But, not as smooth as with CrOxide.
I think I will experiment with the diamond spray.
I will then experiment with the diamond spray, followed by the FeOxide.
Thanks again!

That Iron Oxide Red 110 M light almost sounds too good to be true. Anyone know how big the SiO2 + Al2O3 particles are that make up 4% of the pigment and if they would cause any problems?
