About This Guide

A triple-furnace automatic smelting array with hoppers for input, output, and fuel. Dump raw ore or food in the top, fuel in the side, and collect processed items from the bottom chest without ever opening a furnace. This beginner farm build works in Minecraft Java Edition and Bedrock Edition, version 1.20+ and above. Budget around 10-15 minutes for construction — have all materials in your inventory before you begin.

Difficulty: Beginner

This build earns its Beginner rating because it uses straightforward block placement with no redstone knowledge required. You can finish it in your first survival session using materials gathered from early-game exploration. It’s a great confidence-builder before tackling larger projects.

Materials You’ll Need

Hopper	9
Chest	7
Cobblestone	12
Fuel (coal or wood)	64

Total distinct materials: 5. Gather everything listed above before you start — mid-build supply runs break your momentum.

Step-by-Step Instructions

Step 1: Build the Base Platform

Place a cobblestone platform 5x3 to work on. This gives you something to build the smelter on top of and makes the design look intentional rather than floating. Mark 3 spots in the center row for the furnaces.

💡 Tip: Build the smelter near your base but not inside it — furnaces emit light level 13 when active, which affects mob spawn areas.

Step 2: Place the Furnaces

Place 3 furnaces in a row at the center of your platform. These are your smelting units. Three furnaces running in parallel are 3x faster than one. You can always add more later by extending the hopper chain.

💡 Tip: Smokers smelt food 2x faster. Blast furnaces smelt ores 2x faster. Use specialty furnaces for specific jobs.

Step 3: Add Output Hoppers and Chest

Underneath each furnace, place a hopper. Sneak-click to place each hopper pointing into the furnace below it — this collects smelted output. Chain the 3 hoppers together and connect them all to a double chest at the end. XP orbs are saved for when you break the furnaces.

💡 Tip: Sneaking while placing a hopper connects it to whatever block you click. Click the furnace’s bottom face to connect below it.

Step 4: Add Input Hoppers

Place one hopper on top of each furnace (sneak-click the top face of each furnace). These feed raw materials into the furnaces automatically. Place a large chest above the hoppers as your input chest — dump all your ores and food here.

💡 Tip: One chest can feed 3 hoppers. Use a double chest so you don't run out of input space on long mining trips.

Step 5: Add Fuel Chests

On the side of each furnace, place a chest. Then place a hopper connecting from the chest into the furnace's fuel slot (the bottom-left slot). Fill these chests with coal, wood, or any fuel. The hoppers feed fuel automatically as long as it's available.

💡 Tip: Lava buckets smelt 100 items each — the most fuel-efficient option. Coal smelt 8 items each. Bamboo smelt 0.25 items but you have infinite bamboo.

Step 6: Test and Use

Put some raw ore or food into the top chest and coal into a fuel chest. Within seconds, all 3 furnaces start processing simultaneously. Check the bottom collection chest to see output arriving. Your smelting capacity is now fully automatic and 3x your old rate.

💡 Tip: Hoppers can slow things down because they take 0.1s per item. For mass-smelting loot, blast furnaces + lava buckets + double chests is the fastest setup.
