A special furnace to smelt ancient debris.

I thought about this idea when watching a video about problems with smithing templates, which included the netherite upgrade.
My suggestion is, to have a special unbreakable furnace in a special bastion that can smelt ancient debris or netherite to cover diamond gear. This brings exploration and lore. Could have an X amount of uses before the furnace is broken and the player would need to explore more to find another one.
