Core Viewpoint - The longevity and performance of cast iron cookware significantly depend on material quality, manufacturing processes, and proper maintenance practices, which can lead to vastly different user experiences [2][4][5]. Group 1: Material and Craftsmanship - The market primarily features two types of iron cookware: cast iron (raw iron) and iron sheet (cooked iron), each with distinct material properties and manufacturing processes that affect their non-stick and rust-resistant capabilities [2]. - Cast iron cookware is made from molten iron ore, which is cast into specific molds, resulting in a hard texture, thick base, and thin edges, making it ideal for high-temperature cooking [2]. - The quality of raw materials, such as the removal of impurities like sulfur and phosphorus, and the addition of beneficial elements like carbon, directly influence the cookware's ability to form a stable protective oxide layer [2][3]. Group 2: Maintenance and Usage Practices - Improper cooking habits and maintenance are major factors leading to the premature retirement of iron cookware [4]. - For cast iron cookware, three key behaviors can negatively impact its lifespan: high-temperature empty heating, exposure to acidic foods, and the use of abrasive cleaning tools [4]. - Correct maintenance practices include washing with warm water, drying thoroughly, and applying a thin layer of oil after each use to maintain the protective oil film [4][5]. Group 3: Differences in Cookware Types - Unlike cast iron, iron sheet cookware is formed by stamping and relies on physical or chemical methods for non-stick and rust-resistant properties, often featuring a surface coating that has a limited lifespan [3]. - The non-stick performance of coated iron sheet cookware typically declines significantly within 3 to 6 months, and once the coating is damaged, the underlying metal is prone to rust [3][5]. - Experts recommend using medium to low heat and soft utensils with iron sheet cookware to prolong its lifespan and prevent damage to the surface coating [5].
