Extremely fine powder is ready to use with no milling required!
Fe2O3 Iron Oxide (also known as iron (III) oxide, ferrous oxide,) is the most commonly used form of Iron as a colorant in glazes and clay bodies. When used in amounts greater than 4% it can react as a flux and increase the fluidity of the glaze.
Red Iron Oxide is also used in the manufacture of colored concrete, Thermite and whistle mix for rockets.
This product is an extremely fine powder. Truth be told, this stuff is an absolute pain in the ass to package and gets everywhere. DO NOT open this in the house. I will ship this to you packaged in a plastic bag which is then sealed in a re-usable plastic tub.
