Premier Space-Saving Hard-Anodized Nonstick vs Chatham Ceramic Nonstick 3-Quart Saucepan with Lid: which is safer?

Where these two actually differ

• We flag Nonstick coating degradation and leaching, PTFE fume inhalation (thermal degradation) and Coating separation or peeling over time on the Calphalon and not on the GreenPan.
• We flag Aluminum leaching and Coating degradation and loss of nonstick function on the GreenPan and not on the Calphalon.
• The Calphalon is Hard-anodized aluminum with proprietary nonstick coating (unspecified) where the GreenPan is Ceramic nonstick coating, which is most of the difference in these two grades.
• The gap is 55 points, wide enough that this is not a close call, and the GreenPan is the one to buy.
• We are less certain about the Calphalon grade, at 35% confidence against 78%, because it discloses less.
