Useful for stacking more ore's for quicker cooking time.

You have to place this on the dirt/sand/snow etc, but you still need to protect it! Place wood/stone walls/gates around it, so other players cant loot it without raiding you!

Zach 49 pts. 3 years ago

If you plan on logging off for a while, you might want to put two stacks of fuel and leave four empty slots for charcoal and smelted ore. This is less efficient as it uses more wood for less ore output, however it allows for more ore to smelt without player intervention.

There are few bigger raid magnets than a large furnace. If you're a solo player, you're better off using your neighbor's large furnace (with or without their permission) than building your own and drawing unwanted attention.

600 metal ore = 200 wood, 300 sulfur ore = 50 wood

Nkolik 11 pts. 5 years ago

Spread out your ores in it. You still need 3 slots. 1 Slot for putting the wood in. Another slot for the coal. And for the last spot, your smelted ore. What this will do it would make the cooking time more faster.
