The Crucible Furnace is a multi-block structure added by Mariculture which melts ores down. It is created by placing one Industrial Smelter atop the other. It must be surrounded by a heat sources to function, for example lava. Placing an ore into the GUI of the smelter will melt the ore down into its molten state. By using glass bottles the player can extract the molten ore, providing an alternative to other early game methods of smelting by effectively doubling ore output. Placing these molten bottles of ore into an Industrial Freezer will crystallize the liquid back to its original state.
