The Science of Polymerization Polymerization is a chemical reaction where oil molecules cross-link to form a rigid, plastic-like structure. This slow cooling process helps the oil polymerize uniformly, creating a strong bond.
Repeating this process three to five times builds a robust foundation that will improve with every subsequent use. This is distinct from simply heating oil in a pan; successful seasoning demands precise temperature control and sufficient time for the molecules to align and harden evenly across the surface.
