Iron objects turn reddish-brown when exposed to air because they react with oxygen in the air to form iron oxide, more commonly known as rust. This process is called oxidation and it occurs when iron is exposed to moisture and oxygen. Rust is a brittle compound that weakens the iron structure over time.

Why is your black cast iron stove turning grey?

The black color of cast iron stoves can turn grey due to a process called oxidation. This occurs when the iron is exposed to oxygen and moisture, leading to the formation of iron oxide, which appears as a grey patina on the surface. Regular maintenance and cleaning can help prevent this color change.


Why does rock turn reddish brown?

Rock can turn reddish brown due to the presence of iron oxide minerals, such as hematite or goethite, that have oxidized and formed on the surface of the rock. This oxidation process occurs when iron-containing minerals are exposed to oxygen and water, causing the reddish-brown color to develop.
