Liquid pig iron can be poured into a Ceramic Mold to make unshaped pig iron. It takes 100 units of pig iron to completely fill an empty Ceramic Mold. Once the unshaped pig iron has cooled below it's liquid temperature, it can be placed in the crafting grid to create a pig iron Ingot which will inherit the temperature from the unshaped ingot in the Ceramic Mold. The empty mold will be returned to the inventory; although there is a small chance of it breaking and being lost, breakages are announced with the sound of pottery shattering similar to ceramic jugs.
|Pig Iron Ingot||Hammer||High-Carbon Steel Ingot|
|High Carbon Steel Ingot||Hammer||Steel Ingot|
Pig Iron Ingots are also required in the production of Black Steel, using a Tier 4 Steel Anvil to weld a Pig Iron Ingot to a Weak Black Steel Ingot to produce a High Carbon Black Steel Ingot as follows:
|Pig Iron Ingot + Weak Black Steel Ingot||Hammer||High-Carbon Black Steel Ingot|
The High-Carbon Black Steel Ingots produced by welding Pig Iron Ingots and Weak Black Steel Ingots together on an Anvil have to be worked further on a Tier 4 Steel Anvil to make useful Black Steel Ingots as follows:
|High Carbon Black Steel Ingot||Hammer||Black Steel Ingot|
|Two Ingots||Weld||Double Ingot|
|Two Sheets||Weld||Double Sheet|
Note: Metals are still Workable at Weldable temp.
|Metal||Hot||Very Hot||Faint Red||Dark Red||Bright Red||Orange||Yellow||Yellow White||White||Brilliant White|
