The custom furnace added by the Erebus. It is quite similar to a regular furnace, but it has a much more fancy GUI and can smelt faster (see below). Pipes can transfer lava into an Umberfurnace. It does not produce light whilst smelting.


At first, it works exactly like a regular furnace. If you put in Buckets of Lava, however, it will smelt faster, resulting in a higher fuel efficiency. If you fill up the internal tank completely, it will smelt 80% faster than a regular furnace.

The internal tank can hold 16000 mB (or 16 buckets) of lava, and it consumes 100 mB per smelting process.

Take the following recipe and put a vanilla bucket in the center! Otherwise, you will just get a normal furnace because of how Forge's ore dictionary handles stuff.
