Diorite is a very hard stone that is not subject to corrosion | Forbidden History
Diorite is a very hard stone that is not subject to corrosion and can withstand acids. But what does its "Mohs hardness of 6" mean? It seems to us that it is possible to make any item, but it just needs a little bit more time. Scientists always say that ancient man created such objects almost on an assembly line, using only wood and copper.
On the left are vases and a diorite figurine. They are 5,000 years old. On the right is the researchers' attempt to replicate the diorite vase with copper tools. This is the result they got in six months. Someone is either lying about the production technology or about the level of civilization.
