Mill scale on an anvil. Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron(II) oxide (FeO, wüstite), iron(III) oxide (Fe 2 O 3, hematite), and iron(II,III) oxide (Fe 3 O 4, magnetite).
The bead test is a traditional part of qualitative inorganic analysis to test for the presence of certain metals. The oldest one is the borax bead test or blister test.It was introduced by Berzelius in 1812. [1]
Red iron(III) oxide (Fe 2 O 3, commonly known as rust) is the most common iron oxide used in thermite. [ 14 ] [ 15 ] [ 16 ] Black iron(II,III) oxide (Fe 3 O 4 , magnetite ) also works. [ 17 ] Other oxides are occasionally used, such as MnO 2 in manganese thermite, Cr 2 O 3 in chromium thermite, SiO 2 (quartz) in silicon thermite, or copper(II ...
Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe 2 O 3. It occurs in nature as the mineral hematite , which serves as the primary source of iron for the steel industry. It is also known as red iron oxide , especially when used in pigments .
Iron shows the characteristic chemical properties of the transition metals, namely the ability to form variable oxidation states differing by steps of one and a very large coordination and organometallic chemistry: indeed, it was the discovery of an iron compound, ferrocene, that revolutionalized the latter field in the 1950s.

Minium/red lead – trilead tetroxide, Pb 3 O 4; formed by roasting litharge in air. Naples yellow/cassel yellow – oxychloride of lead, formed by heating litharge with sal ammoniac. Mercurius praecipitatus – red mercuric oxide. Mosaic gold – stannic sulfide, formed by heating a mixture of tin filings, sulfur, and sal-ammoniac.
