2. Rustproofing - Wikipedia

   en.wikipedia.org/wiki/Rustproofing

   There are aftermarket electronic "rustproofing" technologies claimed to prevent corrosion by "pushing" electrons into the car body, to limit the combination of oxygen and iron to form rust. The loss of electrons in paint is also claimed to be the cause of “paint oxidisation” and the electronic system is also supposed to protect the paint. [4]

3. Fordite - Wikipedia

   en.wikipedia.org/wiki/Fordite

   Fordite, also known as Detroit agate, Motor City agate, [1] paint rock, or paint slag, [2] is a lapidarist term for polished pieces of finely layered paint masses from automobile factories. The masses consist of automotive paint which has hardened sufficiently to be cut and polished.

4. Marcellus Formation - Wikipedia

   en.wikipedia.org/wiki/Marcellus_Formation

   In the 19th century, iron ore from these deposits was used as a mineral paint pigment. After being heated in a kiln and finely ground, it was mixed with linseed oil, and used to paint exterior wood on barns, covered bridges, and railroad cars. [30]

5. Bog iron - Wikipedia

   en.wikipedia.org/wiki/Bog_iron

   Bog iron is a form of impure iron deposit that develops in bogs or swamps by the chemical or biochemical oxidation of iron carried in solution. In general, bog ores consist primarily of iron oxyhydroxides , commonly goethite (FeO(OH)).

6. Iron-rich sedimentary rocks - Wikipedia

   en.wikipedia.org/wiki/Iron-rich_sedimentary_rocks

   Iron formations can be divided into subdivisions known as: banded iron formations (BIFs) and granular iron formations (GIFs). [ 3 ] The above classification scheme is the most commonly used and accepted, though sometimes an older system is used which divides iron-rich sedimentary rocks into three categories: bog iron deposits , ironstones , and ...

7. Calcium Lime Rust - Wikipedia

   en.wikipedia.org/wiki/Calcium_Lime_Rust

   Rust, which is primarily composed of iron oxides (Fe 2 O 3), also reacts with weak acids to form soluble iron salts. The reaction can be simplified as: Fe 2 O 3 + 6H + → 2Fe + 3 + 3H 2 O. In this process, iron ions (Fe + 3) are produced along with water, making the rust easier to remove without causing damage to the underlying metal or ...
