The smelter are made for crafting things. Upon opening the GUI, there is a slot for lava buckets, which is the only fuel you can use for this. There is a slot with a coal shape in it, this is where you usually put coal. Then a slot next to that which has an outline of an ingot.

History[edit | edit source]

Official Release
2.015w11aAdded smelter.
15w40aAdded full functionality.
15w43aFixed mining an active smelter, gives you normal idle one now.
15w49aFixed shift clicking in smelter a little bit more..
16w08aAdded smelter upgrades/modes.
Some tech blocks will eventually break down when they're being used. (Idea by CrazyGuy) (Right now it's just the smelter. Others will too later on.)
Changed the smelter GUI a bit.
Added new achievement "Smeltering".
16w13aAdded a percentage number to the damage number on the GUI of the smelter. (It's on the onther guis for the blocks that have tech damage too)
Fixed a very bad bug with the blowtorch and fixing the smelter.
Found a work around with custom recipes. Now you can't put in anything that isn't apart of the recipe; it won't do anything if you don't have the right items in the slots.
16w15aFixed some smelter recipes.
17w11aFixed some tech damage problems. (Maybe, idk)
Added NEI Recipe lookup integration for the custom tech blocks. (Some are a WIP, like the smelter and welder)
Fixed bug with smelter and upgrades not changing the arrow speed on the GUI.
Fixed smelter freezing when an upgrade is added when an item is in the process of smelting.
17w18aRemoved titanium ingot recipe from the smelter. It was kinda weird to use iron in the process of getting titanium.

Bugs[edit | edit source]

Bug; 16w08a: If you open any other GUI but the smelter, you crash. It says something about a blowtorch event, this had to deal with tech damage and fixing it with the smelter. (Bug fixed in 16w13a)

Trivia[edit | edit source]

  • The process of making steel is similar, you add carbon to iron.
  • Even though it's an entirely new block with it's functionality and GUI, you still can get the achievements for steel.
  • The area for the fuel was overlapping the "Inventory" text, which then had to be moved over some.
  • There used to be a recipe for the smelter that used coal and steel to get titanium. This was removed and titanium ore was added instead.
