Bloomery

The Bloomery is a device used to smelt Iron Ore into Iron Blooms which can be worked into Wrought Iron. The iron ores are Hematite, Limonite, and Magnetite. These ores melt into Cast Iron rather than Wrought Iron. All iron-bearing items melt into Cast Iron. To turn them into usable iron, the bloomery is needed. Any iron item can be used in the bloomery, including iron tools and cast iron ingots!

The bloomery is made from 8 Bronze Double Sheets.

A Bloomery

A minimum size bloomery. The bloomery block will open and close with Right Click.

The bloomery can contain up to a maximum of 48 Inputs, with 16 of each item per layer of the chimney. To add layers to the chimney, stack up two more layers of stone blocks.

To add items to the bloomery, climb up to the top and throw items inside. A tower of grey ore should form.

The bloomery consumes 2 Charcoal, and 100 mB of Cast Iron to produce one Bloom. After filling the bloomery with a combination of Charcoal and Ore, light the bloomery block, and wait 15 hours for the bloomery to smelt. When the bloomery shuts off, it leaves behind a Bloom block. This contains Raw Iron Blooms which can be obtained by mining the Bloom repeatedly with a pickaxe.

The Bloom Block

The Raw Iron Bloom must be worked in a anvil to make Refined Iron Bloom.

The Refined Iron Bloom must be worked in a anvil to make Wrought Iron Ingots.

Smith's Notes

• If the bloomery finds itself with more items contained than it can handle based on its chimney, it will try to spit them out the front.
• To retrieve your items from a bloomery that is not lit, do not break the molten block tower. Break the bloomery block.
• Blooms will only melt into cast iron, not wrought iron. They must be worked!
