Ultra copper is a mod that changes how the metals in the game work, and also adds more content to copper, because it wasn't very used.

Soiled raw metals

Now, when you mine copper, gold or iron ores(including deepslate variants) youwill get a soiled raw metal item. This is affected by fortune and silk touch. Before smelting them, you'll have to clean them using one of 3 ways:

-In the inventory, using a watter bottle.

-With the soiled raw metal in the offhand and a copper brush in the main hand, right click.

-Clicking a cauldron that contains water.

This will produce normal raw ores that you can smelt.
