1. Prevent drying and cracking
Rain flower stones must maintain a certain humidity in the natural environment. Some rain flower stones contain water molecules if kept dry for a long time. lose free water molecules and the surface It can crack, especially polished stones and opals, which will crack if left to dry for a long time. During storage, it is best to maintain relative humidity. It is also necessary to avoid mechanical collision, because it will crack and break under the action of external force, so be careful when handling it.
2. Acid and alkali resistant
The main chemical component of Yuhua stone is silica, which is basically neutral. The geological environment in which it is found in nature is also fundamentally neutral. sex. The storage environment shouldt therefore also remain neutral. If it is too acidic or too alkaline, the ions in the acid and alkali will react chemically with the pigment ions in the stone, causing it to deteriorate, corrode, or change color. Under normal circumstances, water is neutral, and acidic or alkaline water will have an impact on Yuhua Stone. When showing, it is best to use distilled water or boiled cooling water. If possible, before using water, you can use pH test paper to test the pH of the water. If the pH value is above 7, it will be alkaline. If the pH value is less than 7, it will be acidic. If it is too alkaline, add a little white food vinegar; if it is too acidic, add a little food alkali and adjust the pH value to 7.
3. Heat and Exposure Prevention
Heating or exposure to intense light will also change the properties of ipigment ons as the temperature increases, causing the Yuhua stone to deteriorate. Keep away from heat sources during storage and avoid exposure to sunlight. Other uses: Yuhuatai was known as "Jubao Mountain" and "Agate Hill" in ancient times due to its prolific production of colored stones. Rain flower stones are not necessarily just for ornamental purposes. Some rain flower stones that have no ornamental value also have value in other aspects.
Paving: Paving the road with Yuhua stones is not only beautiful, but walking barefoot on this road can also play a role in massaging the soles of the feet.
Bonsai: Putting rain flower stones in the bonsai can not only increase the appearance, but also protect the ground surface of the bonsai.

What I know:
In Hezhou region: Ma'anzhou Power Plant, Huangchong Power Plant...
In Wuzhou region: Hemianshi Power Station...
Xijin Hydropower Station, Yantan Hydropower Station, Tianshengqiao Hydropower Station...
Heshan Power Station, power station Beihai Power Station, Liuzhou Power Station, Nanning Power Station, Laibin Power Station...
Each city and county has a power station. The region has 14 prefecture-level cities, 7 county-level cities, 56 counties and 12 autonomous counties (a total of 109 county-level administrative units).
So there should be around a hundred.
