Minecraft: How to make a Blast Furnace
(Read time is about 1 minutes)
5 Iron Ingots + 1 Furnace + 3 Smooth Stone --> Blast Furnace
This 1.15+ Minecraft item acts just like a Furnace... except the Blast Furnace can cook ore items 2 times fast. (But the catch... only ore)
See Smoker or Furnace for ones that can cook stone or food.
