how to make blast furnace

To make a blast furnace in Minecraft, you need the following materials and steps:

• Materials:
  • 1 Furnace
  • 3 Smooth Stone blocks (obtained by smelting regular stone in a furnace)
  • 5 Iron Ingots
• Crafting steps:
  1. First, smelt regular stone blocks in a furnace to get smooth stone.
  2. Open a crafting table.
  3. Place the furnace in the center slot.
  4. Place the 3 smooth stone blocks in a row directly beneath the furnace.
  5. Surround the furnace and smooth stone with 5 iron ingots in the remaining slots.
  6. This arrangement will craft a blast furnace.

The blast furnace smelts ores, raw metals, and metal armor/tools twice as fast as a regular furnace but cannot smelt other items

. For an industrial blast furnace (used in metallurgy), it is a large vertical shaft furnace where iron ore, coke, and limestone are fed from the top and air is blown in from the bottom to produce pig iron. It involves high temperatures (~1650 °C), chemical reduction of iron oxides, and produces molten iron and slag. This type of blast furnace is much more complex and used in steelmaking

. If you are referring to Minecraft, follow the crafting recipe above. If you mean the industrial furnace, it requires specialized equipment and processes beyond simple instructions.
