=======Refining and Types of Furnaces=======

//There are three different outputs of resources when smelting Iron ore within either a Bloomery or Crucible Furnace://

- **Hot Cast Iron** (Mainly used for Armour)

- **Hot Steel** (Mainly used for Weapons

- **Slag** (Waste Product, can be recycled in Crucible Furnace)

There are **two** different types of furnaces that can be used for refining, these are the **Bloomery**, and the **Crucible Furnace**


=======Bloomery=======

{{ :guides:screenshot_2025-03-26_213152.png?200|}}

To create a bloomery, create **two** pieces of **Hard Clay** in a Crafting table (Which takes 8 terracotta each)

To use it, place **iron ore** in the **top** slot, and place **Coal/Charcoal** in the **middle** slot. //Each Iron Ore takes one coal/charcoal to process//

The bloomery can be heated up by using **Bellows** to increase the chance of getting a certain product. To use the Bellows, right click the **bottom** half of the Bloomery while having it in your hand, a bar should appear above the bloomery which displays your current temperature.

**Each Product has an optimal temperature range, and these are:** 

//Slag: Higher temperatures, specifically when the temperature coefficient is above 0.9.//

//Steel: Moderate temperatures, specifically when the temperature coefficient is between 0.7 and 0.9.//

//Cast Iron: Lower temperatures, specifically when the temperature coefficient is below 0.7.//

**Temperature coefficient is the percentage on the bar above the bloomery, so 0.9 is above 90% heat for example.**

To obtain any resources out of the Bloomery, right click it with a pair of **empty tongs**, then right click again on the top of any other block. This should place a ball of molten stuff on top of the block.

Proceed to **hold right click** on it while holding a **hammer** until the ball dissapears. The products should drop around you on the ground or into your inventory. 


**Steel and cast iron can be placed in tongs and used by being thrown into a fire, then right clicking it with a pair of empty tongs** ([[heating_up_cast_iron_and_steel|Heating up Cast Iron/Steel]])



=======Crucible Furnace=======
{{ :screenshot_2025-03-26_212608.png?200|}}

To place a crucible furnace, **you must have the "True Smithing" skill**, on the top of the Mining section of the profession tree, to create it, place **one Clay block on top of a Blast Furnace**, and **right click** the bottom block with a **Hammer**

//Disclaimer: You need craft both a Crucible and an Ingot Cast//

The Crucible Furnace has two input slots (on the left), and 3 output slots (on the right), there is also a "Clear furnace" button on the bottom right 

To use it, place **iron ore or Slag** in the **top-left** input slot and **coal/charcoal** below the iron ore. Each **Iron ore/Slag** creates a certain amount of molten metal within the GUI of the Crucible Furnace.

//How to extract products from the crucible furnace://

1. Place a crucible in the world, then right click it with a pair of tongs.

2. Place the tongs with the crucible into any of the output slots and wait (there must be at least 1.0 molten metal to extract an ingot)

3. take out the filled out crucible and place down an Ingot Cast in the world

4. right click the ingot cast with the tongs, and wait

5. Get a new pair of tongs, then right click the ingot cast

You should then be left with a piece of **Hot Steel/ Hot Cast Iron** in your tongs which you can
use for smithing, or quench in a cauldron to create a solid piece of Steel/ Cast Iron 

**Any molten slag extracted from the Crucible Furnace becomes Cast Iron when placed inside the Ingot Mold**
