What is this coming out of my gold bar?

[nvradar]

I've been refining some gold and this stuff comes out of the melted gold bar as it cools down. I melt the same bar a few times and this stuff comes out less and less til no more comes out, so I know it's a good thing to get rid of. nvradar

I learn more everyday.

If I ever get enough Patience & Knowledge & Equipment I would not mind tinkering with such endeavors.

As there is Gold in Them Hills in my Area.
