Iron Brownish Red Powder Transformation
The change of iron-brown-red
There is iron in the world, and it is hard at first, and the light can be seen from people. Then it is exposed to the air, and through the wind and rain, there are strange changes gradually.
The change of iron often begins on the surface. When it encounters water and gas, its quality gradually shifts. Water moisturizes all things, while iron is the medium for change; those who are qi are mixed in the void and contain all kinds of ingredients. When oxygen and iron meet, they combine.
Oxygen and iron combine at first, if hidden but not obvious. Over time, the surface of iron gradually changes color, starting to be light brown, then turning dark red, and finally becoming a brown-red powder. This powder is loose and brittle, and no longer strong at the beginning of iron.
The reason is that iron is lively and easy to be related to oxygen. Oxygen obtains electrons in iron, iron loses its quality, and its valence state changes. The atomized ions of iron, in association with various things in water and air, gradually become this brown-red powdery substance.
The ancient craftsmen, although they did not understand this chemical principle, knew that iron needs to be well protected. Coat with oil to trap air and water, so that iron can last for a long time. Today's people are well-known in science, and the method of protecting iron is more refined. However, the change of iron-brown-red is also a law of nature and cannot be ignored.
