What is cordierite?
The chemical composition is a silicate rich in iron, magnesium and aluminum. The magnesium in the composition can be replaced by iron or manganese, and part of the aluminum can also be replaced by iron. The crystals are mostly short-column, and occasionally contain inclusions such as sillimanite, spinel, zircon, apatite, and mica in the crystal. The color is generally light blue, dark blue or grayish blue, some are colorless, white, gray, light yellow, light purple or light brown, while weathered, it is slightly green. If the degree of weathering increases, cordierite can be changed to mica, chlorite or talc.
