Crock-Pot
The cooking happens in glazed stoneware under a glass lid, so the food-contact surfaces are ceramic and glass, with the only plastic being the lid knob sitting over the food. That's a genuinely low-plastic configuration for an appliance, even though the brand doesn't pitch it that way. Crock-Pot's public messaging is about lead and cadmium in the glaze rather than plastic, so the plastic-free angle here is incidental to their design, not intentional. The plastic housing and controls on the base are outside the food path.
How clear are their specs?
They document glaze safety well — stating no added lead and citing third-party extractable lead/cadmium testing below FDA and Prop 65 limits — but say little about the knob or base-housing plastics.
Lead testing disclosure
States no lead is added to its glaze and that its parent company tests extractable (leachable) lead and cadmium via accredited third-party labs, keeping stoneware below FDA and California Prop 65 limits. It's a named, testable claim, but the brand doesn't publish the actual test numbers or lab name — an assurance, not a public data sheet.
