What kind of report are you looking on rough material. Just identification. or quality, yield, and value as well?

What kind of material is it?

I have never seen a meteorite look anything like that image.

I have seen lots of slag look like that. In fact, rarely a week goes by here where we don't see a blue slag asking for identification.

How hard is the slag? Is there a metal in the form of silver granules?

Slag is basically industrial waste. It can vary a lot in properties, and often contains metals in various forms.

Hello Sir 1bwana1 Why did not you answer me Are you angry with me. I am convinced of your information about the slag glass but I requested the address of the lab to extract the certificate. Thank you very much.
