Unraveling the Scientific Marvel of Carbon Steel's Non-Stick Quality

in Mamma's Cooking Diary

At Mammafong, we often receive questions about the science that makes our carbon steel woks non-stick. It’s a fascinating interplay of chemistry and physics that turns a simple piece of metal into a culinary powerhouse. Let’s delve into the hardcore science behind this transformation.

The Composition of Carbon Steel

Carbon steel predominantly comprises approximately 99% iron and 1% carbon. This unique amalgamation results in a distinctive crystalline structure that renders it exceptionally robust and capable of withstanding high temperatures. Upon heating, this structure expands, unveiling minuscule pores on the wok's surface. The seasoning process entails heating oil on the wok beyond its smoke point, triggering a reaction known as polymerisation. This marks the genesis of the true enchantment.

The Seasoning Process

The non-stick attribute of carbon steel emanates from a process called seasoning. This involves enveloping the wok with a film of oil and subjecting it to intense heat. The heat prompts the oil to decompose into fatty acids, which subsequently amalgamate with the iron, filling those tiny pores. This engenders a sleek, robust polymerised layer that feels smooth to the touch.

Polymerisation: The Crux of Non-Stick

Polymerisation serves as the scientific essence of the chemical reaction during the seasoning process. As the fatty acids bond with the iron, they give rise to lengthy, resilient molecules termed polymers. These polymers establish a barricade between the food and the metal, thwarting adhesion. The optimal temperature range for this phenomenon to occur lies between 200º and 250º Celsius. With each cooking session, additional layers of polymers accumulate, augmenting the non-stick attributes gradually.

The Protective Shield

As the polymers accumulate, they forge a shield that not only deters food adherence but also safeguards the wok from moisture, thereby thwarting rust formation. Nonetheless, the efficacy of this shield hinges largely on usage frequency. Regular utilization and proper upkeep ensure the wok's surface remains shielded and in optimal condition.

Why Choose Carbon Steel Over Other Metals?

Carbon steel outshines other metals in achieving non-stick properties owing to its aptitude for forming this polymerised layer. Materials like aluminum or stainless steel lack the porous structure necessary for bonding with oil in a similar manner. Carbon steel's distinct composition and structure render it supremely suited for crafting a natural, enduring non-stick surface.

In summary, the non-stick prowess of carbon steel stems from an intricate scientific process involving metal composition, heat application, and oil chemistry. At Mammafong.com, we leverage this scientific prowess to furnish woks that deliver unparalleled culinary experiences.
