When the specific gravity is close to 19.3, the content of pure gold is higher.
When the specific gravity is 18.5, the gold content is 95%.
17.8 contains 90% gold, and so on.

The higher the gold content, the softer it will be, which is why we often see many people bite gold with their teeth in some costume TV dramas to judge whether it is gold or not, because if it is real gold, it will leave tooth marks. We can also judge whether the gold content of gold ornaments is high or not in this way.
