Additional Questions

What is cast iron made out of?

At its core, **cast iron is created from pig iron**, the raw material produced by smelting iron ore in a blast furnace. To make it more relatable, think of this as the so-called “baking” process of iron. Now, cast iron can come directly from its molten form or be concocted through the remelting of pig iron. This doesn’t happen in isolation, though. Quite often, large amounts of iron, steel, limestone and carbon, particularly in the form of coke, are involved in the process.

In my experience as a metallurgist, this process is essential to separate the desired elements and eliminate any undesirable impurities. Having spent years analyzing this production process, I can attest that the creation of cast iron is inherently a delicate balance of different materials and procedures.
