A data pack adding a multi-block structure which lets you get more gold, iron and copper from smelting. Versions 1.15 and 1.16 and for 1.17 (Snapshots).

A lightweight data pack with a rather low amount of ticking functions, optimised to not impact the game's resources!

As seen in the gallery, there is a hopper in the multi-block structure which will receive additional ingots or nuggets from each smelted item. Supported items are:

  1. all iron armour pieces
  2. iron tools
  3. iron sword
  4. iron horse armour
  5. all chainmail armour pieces
  6. all gold armour pieces
  7. all gold tools
  8. gold sword
  9. golden horse armour
  10. gold ore (+deepslate variant)
  11. iron ore (+deepslate variant)
  12. nether gold ore
  13. copper ore (+deepslate variant)
  14. raw copper
  15. raw gold
  16. raw iron

There are two options for how many (and which) items you get from smelting:

  1. ore doubling, meaning two ingots per ore
  2. gold and iron nuggets about 50-60 % of an ingots worth per ore

For items that are not ores you get a random amount of nuggets of the respective material which are based on the amount of ingots you would use to craft them. Normal smelting gives you only one nugget. With this you get a whole lot more!

Per default, ore doubling is enabled. If you want to change that you need to execute a function from chat:
/function bbf:config
This gives a short chat gui in which the player can switch between the two. The player needs to have the permissions to execute commands through chat. (being opped or enabled cheats for the player or world)

Blast Blast Furnaces Minecraft Data Pack

Building the Structure:

The structure needs the following blocks:

  1. hopper (in the middle)
  2. furnace or blast furnace (only 1! adjacent to the hopper)
And either of these brick-blocks for the rest of the structure as seen in the gallery:
  1. bricks
  2. nether bricks
  3. red nether bricks
  4. stone bricks
  5. end stone bricks
  6. mossy stone bricks
  7. cracked stone bricks
  8. chiseled stone bricks
  9. cracked nether bricks
  10. chiseled nether bricks
  11. polished blackstone bricks
  12. cracked polished blackstone bricks
  13. deepslate bricks
  14. cracked deepslate bricks
  15. prismarine bricks
  16. quartz bricks

For the structure to be valid, the block positions around the central hopper have to be filled with these brick-blocks similar to what is shown in the gallery.

As you can see in the Pictures you need to place a hopper next to a furnace or blast furnace. In the hopper, place this "recipe" out of 4 iron blocks, 2 magma blocks and 1 diamond block inside it and then throw a fire charge from your Inventory into the hopper cavity. These are not lost! If you destroy the hopper you'll get these items back.
