The bloodstone hardness is not high
Is the bloodstone hardness high? The bloodstone is produced from the head and tail of the cinnabar strip of the low temperature hydrothermal deposit, volcanic rock or hot spring sedimentary deposit, and the yield is quite limited. The most famous bloodstones are named Changhua Bloodstone and Bahrain Bloodstone. The composition of the bloodstone is mercury sulfide, and the stone is dickite or kaolinite. The hardness of the bloodstone is 2-3 degrees, which is not high. Stones often have mercury spots and a small amount of quartz particles protruding from the stone surface. In addition to the main component of mercury sulfide, chicken blood contains a small amount of coloring elements such as iron and titanium. They are dark dyes. The content of chicken blood is the main reason why chicken blood is different in red. When the content is high, the blood color is dark red. . In addition, the bloodstone also contains different photosensitive elements selenium and strontium, which is the main reason for chicken blood to fade or discolor (showing dark red) under light and heat.
