Adds a foundry block, similar to a blast furnace but can be sped up using lava or different fuel types. Produces slag as a byproduct of ore smelting.

Description

Ol'Foundry

One block. The Foundry smelts like a furnace, but faster with additionnal stuff.

cauldron Dripstone lava accelerator

Slag bricks and dripstone: put a slag bricks block between a lava source and a hanging dripstone tip above a cauldron. Lava drips through at 3× speed.

How it works

Any furnace fuel works. Speed depends on what you burn:

  • Most fuels — 1×
  • Coal / charcoal — 1.5×
  • Magma cream — 2×
  • Blaze rod — 3×

The Foundry also has a 4-bucket lava tank. Fill it and smelting doubles in speed — stacks with the fuel bonus, so a blaze rod with lava hits 6×. The tank drains while it works. Fill it by hand, via the bucket slot, or pipe lava in from the side.

Slag

Ore smelting drops slag as a byproduct. You can:

  • Reprocess it for iron or gold nuggets (lava in the tank gives an extra roll)
  • Craft it into slag bricks
  • Burn it as fuel, or compost it

Other bits

  • Experience banks until you pull the output, same as a vanilla furnace
  • Hoppers work per face: top feeds input, sides take fuel and buckets, bottom pulls output and slag
  • All recipes and byproduct chances are in JEI

Requirements

  • Fabric Loader + Fabric API
  • Minecraft 26.1.2
  • JEI optional
