GreenPan Spectra Thermobond Hybrid Ceramic Nonstick 12" Wok with Lid
Lower concern for typical cooking use, but hybrid ceramic coatings remain less transparent than pure inorganic alternatives.
GreenPan's Spectra line uses a Thermobond hybrid ceramic nonstick coating and publicly claims Teflon-type coating and PFOA absence. However, hybrid ceramic coatings blend organic polymers with minerals, and the full chemical formula is proprietary, no independent lab testing or third-party certification is publicly available for this…
Brand says: “GreenPan markets cookware as 'PTFE/PFOA-free' and uses proprietary Thermobond hybrid ceramic technology”
