Rouge is iron oxide, not lead. Still widely availabl in powder form. Don't know how finely it is ground. Also used as a very fine abrasive for polishing.

I didn't say it was.

As far as iron oxide goes it's available very finely ground. One of the rock people on ebay has it but seldom sells as it's so messy. 1 or 2 um, maybe less as I can't remember. Hence the raddle I used been based on red led oxide. It's not messy and doesn't stain.

If some one wants to try rouge there is plenty on ebay. The seller I bought some off also sold cerium oxide. I asked what the grain size was and also if he had anything finer. If I remember correctly the rouge was 1um. I bought some. Wear rubber gloves if handling it. It's incredibly messy.

There are red versions of cerium oxide available. Grain size of that will be a few um. Lot less messy and might even be suitable mixed in oil.

I think you might be looking for what we call Prussian Blue in North America.

Cheers.

I think it is almost universally known as Prussian Blue, I think it can be got in powder form for mixing with oil etc, used in paint by artists
