What are "synthetic iron oxides"
It is found in most hardware stores. It has many colors
Black(Fe3O4), Red(Fe2O3), yellow(?), Green(?),blue(?)
I'm not sure if yellow or green iron oxides is possible. I might test if the green oxide is Cr2O3 since it looks very similar. Although after messing
around with the red oxide, it seems to be calcined.

If you look up the safety data sheet (SDS, MSDS) it'll tell you what the product consists of

I have a 1 pound bag of yellow iron oxide. It is most certainly possible, but the name 'iron oxide' is somewhat misleading, since it is actually iron
oxide-hydroxide. (FeOOH)
I believe with enough heating it forms red iron oxide.

Honestly most stuff in my country doesn't have msds. Even H2SO4 drain cleaner doesn't mention sulfuric acid on the bottle, just don't mix with basic
drain cleaner. I did get a bag of white synthetic iron oxide, which is calcium carbonate. No idea on the green and blue one.

What is these synthetic oxides used for? I wonder why they would claim it to be iron oxide when clearly it isn't. Does that particular chemical have
lots of uses where you are?

It seems to be used for dyeing. It is in the paint section of most hardware stores.

Pigments. I am amazed at the report of a "white Iron oxide" being offered.
In pyrotechnics, red and black Iron oxides are used as catalysts in such things as whistle mix. There are "natural" Iron oxides offered (crushed iron
ore? RUST?!), as well as synthetic. They can have radically different performances, even among substances which are supposedly all "red Iron oxide" or
"black Iron oxide".
Look at Iron oxides sold as cosmetics ingredients, offered on Amason, eBay & etc.
Rapopart’s Rules for critical commentary:
1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it
that way.”
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.

I'm still not really sure what the dark blue "oxide" is.

I'm guessing they are called "iron oxides" as they are the most commonly used pigments, especially for concrete&masonry work.

I might buy some later and post a image. Maybe it's Prussian blue? Since it's name is pretty misleading.
