–>Understanding Corrosion on Cast Iron
Cast iron skillets are beloved by cooks for their durability and ability to retain heat evenly. However, these robust cookware pieces are not immune to corrosion, a process that can occur for several reasons:
-
Moisture: Cast iron is susceptible to rust when exposed to moisture. Water droplets or condensation can penetrate microscopic pores in the iron’s surface, creating an ideal environment for rust to form.
-
Oxygen: Rusting requires exposure to oxygen. When moisture comes into contact with the iron in the presence of oxygen, the following reaction takes place:
Fe (Iron) + 2 H2O (Water) + O2 (Oxygen) → Fe2O3 (Rust)
-
Acids: Corrosive substances, such as vinegar, lemon juice, or tomato sauce, can break down the protective layer that forms on cast iron and make it more vulnerable to rust.
-
Storage Environment: Storing cast iron in damp or humid conditions can accelerate the corrosion process. Poor ventilation and temperature fluctuations can also contribute to rust formation.
Understanding the factors that cause corrosion on cast iron is crucial for preventing or addressing the issue and ensuring the longevity of your beloved skillet.
