Gold is relatively soft. If it is really pure gold, then the teeth will be bitten, and if you use some force, you will definitely bite some traces.
Yes, although gold is strong, but not hard, when the metal needle is engraved with real gold, it will leave obvious scratches. Bite with teeth can see tooth marks. Folk goldrs often bite with their teeth. It uses the principle of hardness to distinguish the authenticity.
The better the quality of the gold, the softer it itself, so the quality of the quality will have a tooth print.
Really gold bite, of course, there is no tooth printing, gold is very hard, how can there be a tooth print like those BRICS gold bars?
