Great video ! and what to do with your old cupel Would crushing and re-smelting these old wore out vessels capture ANY left over fine gold or silver ? OR if you would come up on some old slag piles from a long gone assay office yield anything worth while ??
Nevermind the cupels if you can find an old assay office sluice that dirt! I have seen some wild stuff come off the floor of old abandoned assay offices.
