This durable material is made up of iron, carbon, and silicon, with additional elements such as manganese, sulfur, and phosphorus, which are added to enhance its properties. Cast iron is renowned for its exceptional heat retention and distribution, making it the preferred material for cooking utensils and stove parts.

Cast iron comes in various types, including grey iron, white iron, ductile iron, and malleable iron. Grey iron, the most common type, is recognized by its grayish hue and high carbon content.

White iron has lower carbon content and is harder and more brittle than grey iron. Ductile iron has a higher carbon content than grey iron but contains magnesium to make it more malleable or flexible.

Malleable iron is created by heat-treating white cast iron to eliminate its brittleness. This versatile material finds use in a wide range of applications, including construction, automotive parts, pipes and fittings, machinery components, and decorative items.

Due to its unique appearance and durability, cast iron remains a popular material for vintage and antique pieces. However, despite its resilience, cast iron can be prone to cracking or breaking under stress.
