How to Make a Smoker and Blast Furnace
Both start from a plain furnace, and both smelt their speciality twice as fast. Use the right one and you halve the wait at the campfire and the forge.
The two recipes
A furnace in the centre, then wrap it for the job you want.
Need the base first? See how to make a furnace, or grab the grids on Astroworld crafting.
Which furnace for what
Meat, fish, potatoes, kelp, any food. Twice as fast as a furnace, the kitchen workhorse.
Ores, raw metal, and metal tools or armour down to nuggets. Twice as fast for everything metal.
Stone, glass, charcoal, terracotta. Slower, but the only one that smelts the non-food, non-metal items.
They double as job blocks
Place one near an unemployed villager and it takes the job: a smoker makes a Butcher, a blast furnace makes an Armorer, Toolsmith or Weaponsmith. A cheap way to set up the trades you want.
