Smelting Furnace

The is one of the Research Modules in Astroneer. Is used to process Aluminum and Copper. It should be noticed that, due to a possible bug, if a player tries to smelt many ores at once and the empty items slots in the smelter module (including the one on top of it) are fewer than the number of ores being smelt, the excessive products might be lost.

It's faster and more energetically efficient to smelt your ores "in bulge", since it takes the same time and energy whether it's one or four ores being processed.
