Comment by 19099 I will to make this post on every ore powder page in hopes of somebody letting me know the answer. Does ANYBODY know if ore powder (copper powder, iron powder, thorium powder...etc.) does have, will have, or for some crazy reason beyond reality did have any purpose in this game except for the soul use of either selling, taking up bag space, or destroying?
