Advanced Smelting Factory
An advanced smelting factory is the second installment for the smelting factory set. It's the next step up from a basic smelting factory. Instead of having only three slots for smelting, this one now has five. This means even faster smelting, and faster production! Much like its basic counterpart, it has an upgrade slot, and also a slot for batteries. This machine can also be upgraded into an elite smelting factory.
