Is stalactite jade? And why do you say you have to soak in salt water for 8 hours before you can bring it?

Stalactites are not jade. Stalactites, also known as stalactites, refer to different forms of calcium carbonate deposits such as stalactites, stalagmites and stone pillars formed in caves in carbonate areas under long geological history and specific geological conditions. The formation of stalactites often takes tens of thousands or hundreds of thousands of years. When stalactites come into contact with acidic substances and carbon dioxide, carbon monoxide will be released, which is harmful to stalactites, so stalactites should be soaked in salt water before they can be brought.
