There are no markings on it. I don't know what metal it is. There are spots that show a copper color. I did not clean it at all. It shows a lot of patina. It weighs about 11 oz. Please check all pictures carefully as they are part of the description. Any questions please ask. What you see is what you receive. If it is supposed to have anything else, it is not included. Thanks for looking and have a nice day!
