I unearthed a heavy iron artifact with a relatively smooth inside 10” OD and an outside that is covered with molten material. The cone end has about a .5 inch circular opening and missile shaped body about 19 “ in length. It was found about 50 ft from the CSX right away here in the mountains of North Carolina. Do you think it could be part of a smelter used on the train tracks? Is there a way to post a pic for you to help determine what this is?
