I had to look up what slag is and it looks like slag is nonmetallic. This item is metallic since the detector gets a strong signal from it. It's not magnetic though. I used some steel scissors and compared scraping some lead that I had to scraping this and this was much much harder to scrape.

If it's lead, that should be easy enough to deduce with a scratch test. If it shows silvery color and the metal is soft, well, there you have it.

It looks like it cant be slag or lead.
