How to Melt Ores and Mix Alloys in the Smeltery

A multi-block smeltery lets you process raw ores into liquid metals, cast ingots and parts, and blend different liquids into stronger alloys.

Melting Ores and Casting Metal

1. Construct your multi-block smeltery in your base—or even inside a pressurized space station room if you are playing alongside space mods.

2. Place your raw ores inside the smeltery to melt them down into liquid metals.

3. Set up your casts for the specific tool parts or ingots you want to produce.

4.

Mixing Molten Alloys

You can unlock higher-tier materials by combining liquids inside the smeltery:

1. Melt down multiple compatible raw materials inside the same smeltery chamber.

2. Allow the molten materials to mix together inside the structure to form unique liquid alloys.

3. Use this method to create specialized alloys such as Manyullyn, Slimesteel, and Pig Iron.

4. Pour the newly mixed alloy into your casts just like standard molten metals to make alloy ingots or tool components.
