Complete guide to choosing safe, non-toxic cookware in Australia
Making thoughtful choices about cookware is about understanding the trade-offs and selecting options that work for your family, budget, and cooking style. Let's cut through the marketing claims and look at what the research actually shows.
Understanding "Non-Toxic" Cookware Claims
When brands advertise "non-toxic" cookware, it's worth being skeptical. Everything has trade-offs, and no material is perfectly safe under all conditions. What matters is understanding the genuine risks versus marketing hype, and making informed choices that reduce unnecessary chemical exposure while keeping cooking practical and enjoyable.
Ceramic-Coated Cookware: The Reality Behind the Marketing
Ceramic-coated pans have been heavily marketed as the healthy alternative to traditional non-stick (which typically contains PFAS forever chemicals). But here's what you need to know: most aren't actually ceramic. They're typically aluminum or stainless steel coated with a sol-gel material containing silica and minerals. Learn more about PFAS in cookware.
Research by Golja et al. (2017) found that some ceramic-coated cookware can release titanium dioxide nanoparticles into acidic foods, with levels increasing as the coating degrades. The European Union banned titanium dioxide as a food additive in 2022 following safety concerns identified by EFSA. It's worth noting that Food Standards Australia New Zealand (FSANZ) reviewed the same evidence and concluded titanium dioxide remains safe at current exposure levels—regulatory agencies weigh precautionary principles differently, and the science continues to evolve.
The practical issue with ceramic-coated cookware is durability. These coatings typically last 1-3 years before losing non-stick properties, meaning frequent replacement. They also can't handle high heat above 260°C (500°F), limiting techniques like high-heat searing or wok cooking. If you choose ceramic-coated cookware, understand it's a short-term investment rather than lifetime purchase.
True pure ceramic cookware (like Xtrema) is entirely different—made from natural clay with no metal core or coatings. It's genuinely non-reactive but expensive ($200-400+ per piece), heavy, unsuitable for induction cooktops, and requires technique adjustments. For those prioritizing absolute chemical-free cooking, pure ceramic delivers, but it demands commitment.
Stainless Steel: Reliable With Minor Considerations
Quality stainless steel remains one of the best overall cookware choices. It's durable, versatile, dishwasher-safe, and free from synthetic coatings. However, research by Kamerud et al. (2013) from Oregon State University found that stainless steel does leach small amounts of nickel and chromium into food, particularly during acidic cooking and with new cookware.
The encouraging finding: leaching decreases dramatically after the first 6 cooking cycles as a protective oxide layer forms. By the tenth use, the average was 88 μg of nickel and 86 μg of chromium per serving of tomato sauce—relatively modest amounts compared to other dietary sources. For most people, this poses minimal risk.
Who should be cautious: Individuals with nickel allergies or sensitivities should be aware of this leaching. If you have contact dermatitis or known nickel sensitivity, consider cast iron, enameled cast iron, or pure ceramic instead.
Quality matters: Look for 304-grade stainless steel (marked 18/10, indicating 18% chromium and 10% nickel) from reputable brands. Multi-ply construction with aluminum cores provides superior heat distribution.
Australian options: Scanpan Impact ($150-300), Essteele Per Vita ($180-350), and international brands like All-Clad available at Peter's of Kensington, Myer, or David Jones.
Cast Iron and Carbon Steel: Genuinely Chemical-Free Options
Uncoated cast iron and carbon steel represent truly chemical-free cookware. When properly seasoned with oil, they develop natural non-stick surfaces through polymerization—oil molecules bonding to create a protective layer.
The iron benefit: Cooking in cast iron naturally increases food iron content. Research by Cheng and Brittin (1991) found that spaghetti sauce picked up about 2mg of iron per 100g when cooked in cast iron, and applesauce picked up 6mg per 100g—compared to negligible amounts in glass cookware. This can be particularly beneficial for those with iron deficiency, vegetarians, or pregnant women.
Important warning for Australians: Approximately 1 in 200 Australians has hereditary hemochromatosis (iron overload disorder), particularly common in those of northern European ancestry. If you have elevated ferritin levels (>300 μg/L), diagnosed hemochromatosis, or family history of iron overload, avoid cast iron and carbon steel entirely. The iron released is bioavailable and will worsen iron accumulation. Consult your GP for iron studies if unsure—this is Australia's most common genetic disorder and often goes undiagnosed.
Practical considerations: Both require hand-washing and periodic re-seasoning. Acidic foods (tomatoes, wine, citrus) can strip seasoning and create metallic flavors during extended cooking. They're also heavy and require preheating for even cooking.
Carbon steel advantages: Lighter than cast iron, heats faster, develops seasoning more quickly. Solidteknics manufactures carbon steel cookware in Sydney with lifetime guarantees ($150-400), offering genuine Australian-made quality.
Budget-friendly cast iron: Lodge skillets available at Bunnings for $40-80 represent excellent value and will last generations with proper care.
Enameled Cast Iron: Low-Maintenance Non-Reactivity
Enameled cast iron combines cast iron's benefits with a glass-like enamel coating (powdered glass fused at over 760°C) that eliminates seasoning needs and prevents reactions with acidic foods.
The enamel coating is genuinely non-reactive—essentially glass—and prevents iron leaching entirely. No seasoning required, and cleaning is straightforward with soap and water. However, it's important to understand what's in enamel glazes. Independent consumer advocate Tamara Rubin of Lead Safe Mama has tested enameled cast iron from multiple brands using XRF technology (the same method used by the US Consumer Product Safety Commission) since 2009. Her publicly published testing has consistently detected heavy metals including lead, cadmium, and antimony in enamel glazes, particularly in brightly colored enamels.
Le Creuset acknowledges that their brightly colored enamels may contain traces of lead or cadmium, though they maintain all products pass California Proposition 65 leach testing, which measures whether metals migrate into food at harmful levels. The company has stated that their Dune and Palm colors are lead and cadmium-free. The distinction matters: XRF testing detects what's present in the material, while leach testing measures what transfers into food during cooking.
Additionally, independent leach testing by Natural Baby Mama found increased levels of aluminum, lead, and cadmium in tomato sauce cooked in Le Creuset, particularly in scratched or worn pieces. The Hong Kong Consumer Council (2024) found that several enameled cast iron brands released excessive metals that exceeded international safety standards.
For maximum caution, consider white or cream interior enamel (which contains fewer colorant additives than bright colors), or choose neutral exterior colors over bright reds, oranges, or yellows. IKEA Vardagen enameled cast iron has a strong track record of testing clean in independent testing. Alternatives include bare cast iron, quality stainless steel, or pure ceramic. If using enameled cast iron, inspect regularly and discontinue use if significant chipping or enamel wear develops.
This information is provided for informed decision-making. Enameled cast iron from reputable manufacturers meets current safety standards, and millions use these products without incident. However, some consumers prefer alternatives based on the presence of heavy metals in glazes.
Australian recommendation: Chasseur is manufactured in Australia at lower prices than European imports ($150-300 vs $300-600+). Supporting local manufacturing while getting safe, durable cookware makes this compelling. Available at Peter's of Kensington, Myer, and David Jones.
Drawbacks include weight, potential chipping if dropped, and staining on light enamel (cosmetic only, doesn't affect safety).
Baking Materials: Glass, Stainless Steel and Silicone
Borosilicate glass (authentic PYREX with uppercase letters) is completely inert—it doesn't leach any chemicals under any circumstances. Look for uppercase "PYREX" marking to confirm true borosilicate, as modern lowercase "pyrex" often uses less durable soda-lime glass.
Limitations: oven and microwave only (not stovetop), slower heating than metal, fragile if dropped. Perfect for baking and food storage that transitions to oven. Budget-friendly at $15-60 for quality baking dishes.
Stainless steel: Stainless steel bakeware offers another genuinely safe baking option. Unlike aluminum baking sheets that can leach, stainless steel is non-reactive and durable. The same minor nickel and chromium leaching considerations apply as with stainless steel cookware (see above), though amounts are modest. Stainless steel bakeware works well for roasting vegetables, baking cookies, and sheet pan dinners. The Low Tox Project (Australian company) offers stainless steel bakeware as an alternative to aluminum or non-stick baking sheets. Stainless steel is dishwasher-safe, lasts decades, and can handle high oven temperatures without concern.
Silicone bakeware: Recent research by Zhu et al. (2025) found cyclic siloxane migration into food during baking, with levels ranging from 680-4,300 μg/g in new bakeware. The positive finding: migration decreased 95% after just three baking uses and continued declining with further use. If using silicone, run it through 3-4 empty baking cycles before first use to reduce initial siloxane levels. The long-term health implications remain uncertain as this research is very new.
A Note About Non-Stick Cookware
Traditional PTFE non-stick (Teflon) has evolved—modern versions don't contain PFOA, which was phased out years ago. However, "PFOA-free" doesn't mean completely chemical-free, and questions remain about replacement compounds.
If you choose to use non-stick: never heat empty pans, discard when coatings show wear, use low-medium heat only, and consider it a 3-5 year disposable item, not lifetime cookware. For those seeking to minimize chemical exposure, the materials in this guide offer better alternatives. For me personally, I don't use non-stick cookware.
Making Your Choice: Practical Recommendations
Best overall for most families: Quality 304-grade stainless steel for everyday versatility, durability, and proven long-term safety. Scanpan Impact or Essteele ($150-300) represent excellent Australian options that will last 20+ years.
For genuinely chemical-free cooking: Cast iron (Lodge $40-80) or carbon steel (Solidteknics $150-400). Budget-friendly, lasts generations, improves with use. Just confirm you don't have iron overload concerns first.
For acidic dishes without maintenance: Enameled cast iron, especially Australian-made Chasseur ($150-300). Perfect for tomato sauces, wine reductions, slow braises.
For baking: Borosilicate glass (PYREX, $15-60). Genuinely inert, budget-friendly, lasts decades. The Low Tox Project, an Australian company, has a wide range of stainless steel bakeware, some products have a nickel-free option.

Induction Cooktop Compatibility
Many Australian homes now have induction cooktops. Compatible materials include stainless steel (with magnetic base), cast iron, carbon steel, and enameled cast iron. Not compatible: aluminum (unless special magnetic base), glass, ceramic, or copper. Quick test: if a magnet sticks to the bottom, it works on induction.
Maintenance and Lifespan: The Real Cost
When evaluating cookware costs, consider cost-per-year rather than just purchase price. A $150 ceramic-coated pan that lasts 2 years costs $75 per year. A $300 stainless steel pan that lasts 25 years costs $12 per year. Budget cast iron at $60 lasting 50+ years costs about $1 per year.
Dishwasher safety matters too: Stainless steel and borosilicate glass are dishwasher-safe, making them convenient for busy families. Cast iron, carbon steel, and enameled cast iron require hand-washing (cast iron and carbon steel to preserve seasoning, enameled to prevent harsh detergent dulling the enamel).
Cooking Tips for Better Results and Longevity
Stainless steel non-stick technique: Preheat your pan for 2-3 minutes over medium heat, add adequate fat (oil or butter), then add food. A properly preheated stainless steel pan with enough fat performs nearly as well as non-stick for most foods.
Cast iron and carbon steel care: After washing (hand-wash only with minimal soap), dry thoroughly and rub with a thin layer of oil before storing. This prevents rust and maintains seasoning. Store in a dry place—moisture is the enemy.
Protect your cookware surfaces: Use wooden, silicone, or food grade silicone utensils with all cookware except stainless steel. Metal utensils can scratch ceramic coatings, strip seasoning from cast iron, and damage hard-anodized surfaces. Only stainless steel can handle metal utensils without consequence.
Cooking oil matters too: Even the safest cookware becomes problematic with oxidized oils. For high-heat cooking above 200°C, use avocado oil (smoke point 270°C) or ghee (250°C). Save extra virgin olive oil for medium-heat cooking under 190°C, as it oxidizes at high temperatures creating harmful compounds.
Your Transition Strategy
You don't need to replace everything immediately. Start with your most-used pan—probably a 24-28cm frying pan you use daily. Replace it with quality stainless steel or cast iron. As budget allows, add enameled cast iron for acidic dishes or carbon steel for high-heat cooking. Gradually phase out ceramic-coated or non-stick pieces as they wear out naturally.
This gradual approach spreads costs over time while reducing chemical exposure where it matters most—your everyday cooking.

Final Thoughts
The goal is about making informed choices that reduce unnecessary chemical exposure while maintaining practical, enjoyable cooking. Every material involves trade-offs between safety, convenience, cost, and performance.
For most families, quality stainless steel for daily use combined with cast iron or carbon steel for high-heat cooking and glass for baking provides excellent balance. Those with specific health concerns (nickel allergy, iron overload) can adjust accordingly.
Start with one quality piece in the material that suits your cooking style, and build from there. Your kitchen doesn't need to be completely "non-toxic" overnight—every thoughtful swap toward lower-tox materials is a positive step.
