The Smelter is used to smelt Metal Ore, Copper, Sand, Seaweed, Explosive Goo and Titanium Ore. It is fueled by Planks just like the Engine and can hold a maximum of four. Each Plank will last for 50 seconds before it is completely burned up. The Electric Smelter is an upgraded version of the Smelter.

|Metal Ore||Metal Ingot||80s|
