The Great Cookware Debate
Choosing the right pan can feel complicated. For decades, 'non-stick' coatings promised ease and speed - but at a cost. Teflon and other synthetic coatings break down over time, releasing harmful compounds and creating waste that can’t be repaired or recycled.
At Ironclad, we believe cookware should never come with a health or environmental trade-off. Our pans are made to outlast trends and generations. Naturally non-stick through proper seasoning, with our seasoned cast iron range being guaranteed for three lifetimes by our Three Generation Guarantee.
Performance Comparison: Cast Iron vs Coated 'Non-Stick'
Heat Retention and Cooking Quality
Cast Iron: Holds and distributes heat exceptionally well. Perfect for searing, browning, baking, and slow cooking. Once hot, it stays hot - delivering restaurant-quality results at home.
Coated Non-Stick: Heats quickly but loses temperature fast. Synthetic coatings degrade at high heat, making them unsuitable for serious cooking or searing.
Versatility
Cast Iron: Works on gas, induction, electric, grill, and open flame. Oven-safe and perfect for stovetop-to-oven cooking.
Coated Non-Stick: Limited to low-to-medium heat and stovetop use. High temperatures can damage the surface and release toxins.
Durability
Cast Iron: Built to last for generations. Seasoning improves with use. Any wear can be restored with simple care.
Coated Non-Stick: Coatings wear, flake, and peel over time - and can’t be repaired once damaged.
Sustainability
Cast Iron: Designed to last a lifetime. Fully recyclable. Free from synthetic coatings and harmful chemicals.
Coated Non-Stick: Typically lasts 1-2 years before replacement. Most coatings are non-recyclable and end up in landfill.
Why Cast Iron Wins for Every Kitchen
If you want power, versatility, and longevity without compromise, cast iron is the clear choice.
Searing and flavour: Exceptional heat retention creates that deep, delicious crust.
One-pan versatility: Sear, bake, braise, fry, or roast - all in one pan.
Naturally non-stick: A seasoned surface releases food easily, without synthetic chemicals.
Repairable: Rust or dull seasoning can always be restored.
Sustainable: A “buy once” tool that becomes an heirloom.
For those seeking a lighter option, wrought iron or stainless steel can offer similar longevity without toxic coatings - but none match cast iron’s depth of flavour and heat performance.

Price vs Value
Coated pans might appear cheaper up front, but replacement costs add up fast. A single, high-quality cast iron pan can outlast 5–10 synthetic non-stick pans - and with Ironclad’s lifetime guarantee, you’ll likely never need another.

Common Myths About Cast Iron
“It’s too heavy.”
Its weight gives it the ability to hold heat evenly and most people stop noticing after a few uses.
“It’s hard to clean.”
It’s simpler than you think. Wash with warm water, dry, and lightly oil. That’s it.
“It’s only for meat.”
Not true. Cast iron is brilliant for vegetables, pancakes, tofu, breads and desserts.
FAQs
Is cast iron non-stick?
Yes - naturally. A well-seasoned cast iron pan develops a smooth surface that releases food easily, without synthetic coatings.
Can I use metal utensils with cast iron?
Absolutely. They won’t harm the surface.
How long does synthetic non-stick last?
Typically just a few years before the coating breaks down. Cast iron lasts for decades or more.
Does cast iron work on induction cooktops?
Yes. It’s naturally induction-ready and performs beautifully across all heat sources.
Can cast iron replace non-stick completely?
Yes. With proper seasoning and heat control, it does everything non-stick can - and much more.
Final Thought
Synthetic non-stick is a shortcut with a cost to your health, your wallet and the planet. Cast iron is the real non-stick solution: natural, sustainable, and built to last for generations.
At Ironclad, we don’t believe in temporary cookware. We believe in heirlooms that tell your home’s story, one meal at a time.
