Step-by-step explanation:
Two items that are commonly made of cast iron include cookware such as skillets, and decorative items like garden benches. Cast iron is known for its durability and heat retention properties, making it an excellent material for cookware. Skillets made from cast iron are prized by chefs for their ability to evenly distribute and maintain heat. On the other hand, cast iron garden benches are appreciated for their robustness and intricate designs. Historically, as indicated by archaeological findings such as a 26" long iron model of a cookstove from a Koguryo tomb, cast iron has been used for a variety of purposes, from cooking to heating. Iron's value extended beyond its practical uses; it also symbolized social power and served as currency in ancient markets.

Two items that are often made of cast iron are cookware such as frying pans and pots and sewer pipes. Cookware made of cast iron is known for its heat retention and even heating properties, while cast iron sewer pipes are durable and resistant to corrosion.
