Excuse me, what is the name of that ancient object based on? ...

Probably the purpose, sometimes according to the ornamentation or words on the objects. To say why it is a word, it should be pictographic, such as "Ding", which is very similar to the shape of Ding.

The names we modern people say may be different from those in ancient times. We mainly named it according to the textual research of documents, as well as the shape, pattern, characters and times.
