While the process of building a patina is straightforward, the science behind it requires a fat that can polymerize evenly without breaking down. For this reaction to occur cleanly, the oil must remain stable at high temperatures.

Unrefined Alternatives When browsing oil options, the distinction between refined and unrefined is critical for heat tolerance. The Science of Polymerization and Heat Stability Seasoning cast iron is not just about adding a layer of oil; it is a chemical reaction where triglycerides break down and reform into a hard, plastic polymer.
Their high polyunsaturated fat content aids in creating a slick, smooth surface that feels non-stick to the touch. Step-by-Step Methodology Begin by thoroughly cleaning the cast iron to remove any manufacturing oils or residue, using hot water and a stiff brush.

This polymerized layer is what provides the non-stick properties and rust resistance. The goal is to apply a thin, almost imperceptible layer of oil and then bake it until it polymerizes.
