Hello,I recently found this heavy green and purple rock while metal detecting,I cut it in half when I got home to find it is gold colored inside and none magnetic.I wonder if anyone can help me identify it.
Definitely looks like slag. Where did you find it?
I found it in a park that is over 100 years old,before that it was just farmland.It is the only piece like this I have found in many years at this location.
There is a roman Villa that was unearthed a few years ago 4 fields away,I wonder if it could be roman slag?
