Hi Cord!

Those are some interesting samples. Have you tested their physical properties? Are they mallable (can be pounded flat)? Are they magnetic? Do they have a streak (mark left on unglazed porcelain)? How hard are they? Have you estimated their density?

More advanced tests require chemicals and, ultimately, you will want an assay (fire, ICP or AA) before you send them to a refiner.

I believe I sent some dore to that refiner before. They were easy to work with and reputable. I will check my records and confirm.
