Or is a misstake. Carbon dating has a huge problem of specimen contamination. Maybe somebody boobed at the lab. A journalist heard the story ran it and when the scientist did a re-check and got back to the journalist, it wasn't news any more.

If something requires knowledge in metalurgy that first was discovered in the 15'th century then we know it can't be older. A good scientist entertains every avenue, but in most cases the truth is painfully obvious to everybody involved.
