Refining raw copper block into copper block

This mod simply adds a somewhat useful feature, the raw copper block can be directly placed into the furnace for smelting into a copper block without firstposing into raw copper, the mod's original intention is to facilitate miners to quickly process a particularly large amount of copper in a space-saving manner.

(There may be some grammatical errors in this mod, because I am Chinese Junior high school student,please forgive me.Think you!)
