Help figuring out what this is?

[meatballflavor]

I’m new to metal detecting and most Random finds with no writing or shape I’m clueless on, so bare with me. I found this yesterday and before tossing it away, I broke the top off and the metal sparkles like a bunch of small diamonds. Does anybody know what type of metal this is so I can learn? It’s very dense/heavy, pinged very strong on my metal detector. The outside looked similar to concrete.

Looks like metal slag from being melted in a Fire..

Hard cast lead or printing lead which has antimony in it that fractures like you described

Melted zinc is possible also.
