Refined oils, on the other hand, are processed to remove these impurities, resulting in a cleaner burn and a smoother, more consistent polymerization. The Science of Polymerization Seasoning is not just about baking oil onto the metal; it is a process of thermal polymerization.
Understanding Patina Development and Polymerization in Cast Iron
A thin, even layer of oil is applied to the entire cooking surface, including the exterior, and then baked in a preheated oven at temperatures between 400°F and 500°F. Understanding the science and selecting the proper fat is the difference between a sticky, frustrating pan and a vessel that becomes more valuable with every meal.
This creates a cross-linked network that is hydrophobic and slick, effectively sealing the porous metal and providing a non-stick surface. Why the Right Oil is Non-Negotiable Not all cooking oils are created equal when it comes to polymerization.
How Patina Develops and the Role of Oil in Cast Iron Seasoning
The right oil and technique create a slick, durable patina that not only prevents rust but also improves with use, developing a natural non-stick surface over time. Using a poor-quality oil or one with a low smoke point is the most common cause of sticky, ineffective seasoning, leading to frustration and a cycle of constant scrubbing.
