This Guide gives you an overview over Furnaces and their use.

Furnace Strategy[]

  • You can use a Icon furnace.png Furnace, an Icon improved furnace.png Improved Furnace and Icon CraftingStation Furnace Kiln.png Improved Furnace (Kiln)
  • Recipes, burn times and Thrall Benefits are the same in every type of furnace, the only thing that differs is the number of slots in its inventory.
  • A bigger inventory is better to reduce a possible downtime of the furnace because you can put more stacks of stuff into it. But if you struggle in early and mid game to upgrade to Improved Furnaces, then better stay with standard Furnaces and just build more of them.
  • At least one furnace must have a Icon round bottomed mould.png Glass Flask Mold to be able to produce Icon round bottomed flask.png Glass Flasks. Put every Icon glass.png Glass and Icon crystal.png Crystal into it to collect a suply of Glass Flasks (for Icon water orb.png Water Orb/Orbs and Icon purified water.png Purified Water/Food).
    • Crystals could also be a source for Icon salt.png Salt/Food, but Salt could also be made from Icon stone-1.png Stone which is easier to collect in masses.
  • This furnace could also be the Multi-Purpose-Furnace, where you also put in other stuff like Icon silver.png Silverstone or Icon gold.png Goldstone or Icon starmetal ore.png Star Metal Ore.
  • For a long time you might have more furnaces than Smelter-Thralls. As you get your Thralls put them in order of their level into the furnaces, the same order you want to fill your furnaces with ressources. Then you get your products faster and with a lower amount of burned fuel. In times with a high demand you can also let the empty or low level thralled furnaces run, if fuel or ressources are low you just use the most efficient thralled furnaces.
  • Don't put every possible ressource into a furnace because you might not get out the product you want the most. Candidates for this unwanted use are Icon ingredient steelfire.png Steelfire (turns Icon iron ore-1.png Ironstone into Icon steel bar.png Steel Bar instead of just Icon iron bar.png Iron Bar), Icon brimstone.png Brimstone (turns Icon iron ore-1.png Ironstone or Icon iron bar.png Iron Bar into Icon hardened steel bar.png Hardened Steel Bar instead of just Icon steel bar.png Steel Bar) and Icon ingredient building binding.png Stone Consolidant (turns Icon stone-1.png Stone into Icon ingredient hardenedBrick.png Hardened Brick instead of just Icon ingredient brick.png Brick).
  • It is up to you if you use only a specific recipe for a specific furnace or if you switch recipes according to your demand.
  • Icon obsidian bar.png Composite Obsidian can only be made in the Volcanic Forge, which only exists once on the whole map and has no slot for a thrall. If you want to make it, you have to take at least a lot Icon steel bar.png Steel Bar with you and collect Icon obsidian.png Obsidian on the way or take it with you from previous Volcano-Trips. 10 Icon obsidian.png Obsidian and 1 Icon steel bar.png Steel Bar take 10 seconds to make 1 Icon obsidian bar.png Composite Obsidian.

Fuel Strategy[]

  • In the beginning every fuel is good enough. Most likely you have to use Icon wood-1.png Wood.
  • Put only one type of fuel into one furnace. One type of fuel is picked and the furnace will stop after it is consumed without continuing with the next type of fuel. You then would have to press start again. Therefore additional types of fuel only take away the slots in the furnace. If you have a mixed supply of fuels then put one type in the first furnace, the next type into the next etc.
  • Some fuels have higher priorities and should not be used as fuel in the furnace:
    • Only Icon bark-1.png Bark can be used as fuel in the Icon tannery.png Tannery / Icon epic tannery.png Improved Tannery (to make Icon hide-1.png Hide) and in the Icon dryer.png Dryer (to make Icon drywood.png Dry Wood). It would be a waste to use it for other purposes.
    • Icon branch.png Branches is used in a lot of recipes. Some have a high demand of it like Icon spike.png Spike and various types of Arrows. Better save the Branches for theses things. It also has a very bad burntime.
    • Icon plant fiber-1.png Plant Fiber is used in a lot of recipes and will go in masses into Icon ingredient rope.png Twines, Icon gruel.png Gruel, Icon spice.png Spice or Icon fertilizer.png Compost. It also has a very bad burntime.
    • Icon wood-1.png Wood is a acceptable but possibly lacking fuel for the first steps into the game. Most of the first building blocks (like Icon Foundation-1.png Sandstone Foundation or Icon wooden box.png Wooden Box - until you can make Icon chest.png Large Chests) and the workstations need relatively huge chunks of wood. Later a lot of it will go into Icon drywood.png Dry Wood and Icon ingredient plank.png Shaped Wood.
  • Some fuels are better to use for smelting:
    • Icon coal.png Coal: In the Beginning Coal is not as present as you would need it and with bad tools you would have trouble to make it your primary fuel. Later it can be collected in larger quantities and is a possible fuel. A possible bottleneck could be Icon ingredient pitch.png Tar. If your playstyle involves the constant use of Skinning Knifes you might not have trouble making Tar. But if you have trouble, you could use Coal with a bad 25:1-Ratio to make Tar.
    • Icon drywood.png Dry Wood: It is used to make Icon insultated wood.png Insulated Wood, but what is left could be used as an excellent fuel.
    • Icon oil.png Oil: It is recomended to have some Oil left for other purposes (like Icon modkit wpn increaseDamage t2.png Weapon Damage Kit), but that could stay in a Icon liquid separator press.png Fluid Press. Every additional Oil could be used as fuel. Oil can be massproduced with Icon fishing trap.png Fish Traps. For one Oil you need 1 Icon rawBadFish.png Unappetizing Fish or 5 Icon rawFish.png Savory Fish or 10 Icon rawGoodFish.png Exotic Fish. One Fish Trap won't bring you very far, but what about 10, 50 or 100 Traps? You don't have to run around the world to collect stuff, just collect the slowly but automaticly catched fishs, put them into an array of Fluid Presses and have as much Oil as you want. These three types of Fish can also be cooked into Icon meat strips.png Fish Strips, as food for yourself and your Thralls, which allows you to constantly use a Skinning Knife instead of a Cleaver on animal corps.

Chest Organization[]

At first storage space is rare and ressources will be stored everywhere, sometimes even furnaces and other workstations can be used as a temporarly storage. Later storage rooms can be a valid strategy where you have a lot of chests to store everything. To reduce travel time and distance a few chests around your smelting area can save you a lot of time. It is worth to place furnaces and chests early on in an organized way, Icon wall sign.png Wall Signs can help.
