Choose the right station for ores, meals and everyday smelting, and avoid putting items in a furnace that cannot process them.
Three stations with different jobs
A regular furnace is the flexible baseline station for smelting supported items, including food and many raw materials. A smoker is specialized for food. A blast furnace is specialized for applicable ores, raw metals and metal equipment. Neither specialized station replaces every recipe accepted by a normal furnace.
The main benefit of a specialized station is faster processing for its supported inputs. That does not mean you should replace every furnace in an early base. A mixed set of stations is more useful when your inventory contains both building materials and food.
Organize fuel and inputs efficiently
Keep smeltable materials beside the appropriate station and avoid dedicating all your fuel to a single large batch if you expect an urgent food or ore need. The fuel source and the size of your batch matter to efficiency, but recipes and burn durations should be verified against the edition you actually play.
For a small starter base, one furnace can cover many tasks. As the base grows, give food its own smoker and metal-processing tasks their own blast furnace. Sorting input chests by output purpose makes it obvious where unprocessed resources belong.
What to check when nothing smelts
If a station will not accept an input, confirm whether that type of block or item is eligible for its specific recipe list. For example, a blast furnace is not a universal stone-processing machine. Also make sure the output slot has space and that the station has working fuel.
Do not confuse a crafting recipe with a smelting recipe: some items require a crafting table even if their ingredients came from a furnace. The recipe book and official wiki entry are the best references when the correct processing path is unclear.
