Describe the bug
・You can smelt an Anvil with Wrought Irons and macerate back into Irons
this potentially breaks the game balance
・Smelt an Anvil with Irons then smelt it into Wrought Irons using the Arc Furnace
is much faster than just smelt Irons in the Arc Furnace
(25.60+2.80=28.4s for the Anvil to the Wrought Iron)
(2.80*31=86.8s for the Iron to the Wrought Iron )

Versions
Forge: 14.23.5.2860

Modpack: GregTech Community Pack

Expected behavior
Anvil cannot be made of Wrought Iron
Smelting Anvil takes much longer time
