Small cupel for metal refining, Spanish colonial (1600s), rare. 15 grams, 1-3/4" tall, 1-1/4" in diameter. It is probably very rare to find intact one of these delicate tools of the metalsmith trade, a tiny round-bottom pitcher with spout, due to the rather thin material from which it was made (which can nevertheless withstand high heat!), crack down one side but otherwise stable and intact.
Estimate: $100-200
