tellurides

So I'm new to all this, and have been crawling past hurdle after hurdle, but as of yet, denied success. I made my own kiln that can go excess of 2000 degree F, I've roasted my ore cons, I see gold, or what I think is gold, then as I go through cupellation, the lead cooks off, the gold seems to...

I'm wondering if this is calaverite , pyrite, or galena. It is very soft - but not as heavy as gold. It shines like silver and gold. Any ideas? Thanks for any feedback.
