Most pots and pans never get tested. The ones that do test poorly more often than the marketing admits. Know Your Cookware reads the science, the lab results, and the lawsuits, then tells you which brands earned a passing grade and which to skip.
The FDA approves the materials. The states regulate (some of) the chemicals. The brands write the marketing. Nobody pulls it together for the person standing in a kitchen aisle holding two pans and trying to figure out which one to bring home.
We do that. We read every Lead Safe Mama XRF result, every Mamavation PFAS test, every Consumer Reports lab report, and every state PFAS-cookware bill. Then we write the verdict in plain language with the citation linked.
Third-party lab tests confirm no PFAS, no lead leach above Prop 65, no cadmium. Examples: All-Clad stainless, Stargazer cast iron.
Independent lab data plus consistent manufacturer transparency. Examples: Caraway, Our Place, Made In CeramiClad.
Uses PTFE, has color/glaze concerns, or relies on manufacturer-only testing. Examples: T-Fal, Calphalon nonstick, Le Creuset red/orange.
Failed lab tests, recalls, false-marketing settlements, or known regulatory action. Examples: HexClad legacy hybrid, vintage Lodge enameled.
The default kitchen workhorse. No coating to fail. Independent migration studies show negligible nickel leach for non-allergic cooks. Outlasts every nonstick pan ever sold.
Tamara Rubin's XRF tests came back lead non-detect, cadmium non-detect, mercury and arsenic non-detect. Lighter and smoother than Lodge, with a real lifetime warranty.
Most transparent ceramic-coated brand on the market. Publishes SGS and NSL Analytical reports — 200+ PFAS and 20+ heavy metals tested non-detect. Plan to replace every 1-2 years.
What the C8 Health Project, ATSDR, and the bird-death studies actually show. Severity tier: HIGH for overheating, MEDIUM for normal use.

Stainless · CadmiumKamerud 2013 found tomato sauce raised nickel up to 26-fold. For most people: not relevant. For nickel-allergic cooks: yes.
AluminumThe 2025 meta-analysis is suggestive, not causal. Anodized aluminum leaches an order of magnitude less. Most aluminum panic is overcalibrated.
Cast IronFor most cooks, the iron is a benefit. For ~1 in 227 with hereditary hemochromatosis, it isn't. Carbon steel is the alternative.
