Huh, I knew the Item Barrels / Mass Storages could collect dusts of different sizes, but I didn’t know they could convert between different sizes of metallurgical shapes (nugget / chunk / ingot / blocks) as well. Cool! TIL.
As an aside, it might be a good idea to add a tooltip line to the Item Barrels / Mass Storages mentioning they can do this. I’m not sure if this feature is documented anywhere else.
