Ing/Ed Clauses and Relative Clauses

Hello there,

Can I ask you some questions regarding ing/ed and relative clause?

There are two types of relative clauses -- defining and non-defining. When we use a non-defining relative clause, we must use a comma. Moreover, we can use ing/ed clauses instead of relative pronouns. I wonder whether when we use ing/ed clauses, the rule which is using non-defining clauses regarding comma is apply to ing/ed clauses.

For example, I visited a statue which is located in the center of Paris = I visited a statue located in the center of Paris.

I visited the statue of liberty, which is made of copper. In this situation, which sentence is correct, I visited the statue of liberty made of copper, or I visited the statue of liberty, made of copper.

Or, Are there any rules regarding ing/ed clause on whether ing/ed clauses do not use as a non-defining clause like relative pronoun that.

Thank you!
