NOTE: Lava and Water can be placed in the smeltery by right-clicking on a smeltery drain with the appropriate bucket, or by using buildcraft-compatible pipes

Obsidian Ingots

Obsidian Ingots are created when Molten Obsidian is poured from the Smeltery into an Ingot cast.

Obsidian Ingots can be used to create new Ingot casts.

Crafting

9 Obsidian Nuggets can be put into a Crafting Table to create an Obsidian Ingot, and vice-versa.

When a Chisel is used on Obsidian ingots, an Obsidian Brick is created. When used again on the Brick, a Fancy Obsidian Brick is created.

In Tool Parts

Obsidian has one of the lowest durabilities of any material. It also has the Reinforced III trait, which gives a 30% chance of not using durability. Combined with Diamond and Emerald, it is one of the best pickaxe heads. It can be used for Tool Rods, to give Reinforced III, but is one of the very worst bow materials.

Trivia

  • It is more efficient to put obsidian in the smeltery since its ingot value is doubled.
  • Despite being the hardest block available in survival, Obsidian does not make good tools. This is referenced in its description in Materials and You: Volume 1.
