South red agate ingredients
What is the composition of South Red Agate? Let's take a look at it together.
The chemical composition of agate is SiO2; it can contain elements such as FeAlTiMnV, and it has various colors, which are concentric and regular strips. It can be divided into silk agate, striped agate, moss agate, fire agate, onyx and so on. Among them, red agate is the top grade of various agates. Therefore, in the "Ge Gu Essentials", there is a saying that "agate is not red."

Agate is a common silicon oxide mineral. It is basically quartz, and many of its properties are the same as quartz. The rain stone we are familiar with is actually agate. Agate is also a variant of chalcedony in mineralogy. It is available in a variety of colors and is often in a variety of colors. Generally translucent to opaque. Agate is a low-grade gem, but humans have been processing it into crafts for a long time. There is water in some agates, called water agate. This kind of agate can still make a sound of water when it is shaking, which is very strange.
