"That's… Good to hear," it was different from what Sara had in mind, but it did the trick.
"But I'll need some time to make such an oven," Agnus hesitated before adding, "also do you know how fierce the fire needed for this ore?"
"Well…" Arthur turned to his expert, Sara. But the latter seemed oblivious to such a question. "We can work it out and try the fiercest fire first."
"Works fine for me," Agnus didn't disagree before adding, "but we need to speak about the mold. After liquifying the ore, it's best to work on it when it's still fresh."
"We need to make coins," Sara said, "circular and flat shaped coins. The coin will be in the size of a closed human fist or slightly smaller. It must be not too heavy to handle, or too light to discard."
"Hmm…" Agnus closed his eyes for a second there, "so you want to make this mold to create as many coins as possible in the shortest time, right?"
