Smelter

"Smelting ore down to useable ingots has never been this easy! Feed it whatever ore you find, set the recipe, and out comes the life-blood of any successful factory!"

- Caterina Parks's assistant Steve

The smelter is a building used to smelt base ore into usable ingots.

Smelting
The smelter can be overclocked using Power Shard. This overclocking increases the power demand and input/output capabilities of a single smelter. The chart above shows the various levels of overclocking. The input and output are identical.

Speculation
The trailer shows a machine with a different appearance to the smelter shown on the website, which is performing the described function of the smelter, indicating that there may be more than one type, or that the design has been changed. Mk.2 Smelter might be accessible in the future updates.
