360 Cookware
360 Cookware's whole line is uncoated surgical (T-304) stainless steel with no nonstick, no glaze, and no PTFE. Their slow cooker sidesteps the two contested parts of the category at once: there is no glazed stoneware crock (so no lead or cadmium glaze question) and the vapor-seal lid is solid stainless with no plastic knob or silicone gasket. The pot is a genuine piece of stovetop-capable cookware that drops onto a plug-in warming base. About as materials-clean as a slow cooker gets, at a premium price.
How clear are their specs?
States the surgical-grade (T-304) stainless construction plainly and confirms there is no coating or glaze; the design is simple enough that the material story is fully legible.
Lead testing disclosure
Doesn't publish its own lab reports, but after independent XRF testing (Lead Safe Mama) of multiple 360 Cookware pieces - a saucepan, a slow cooker, and cookie sheets - came back non-detect for lead, cadmium, mercury, arsenic, and antimony, the company became a paid sponsor of Lead Safe Mama's newsletter (November-December 2025) and agreed to have Lead Safe Mama advise on materials for future product iterations before manufacturing. That is a brand actively funding and engaging with independent testing on the strength of good results, though the sponsorship/results are hosted on tamararubin.com rather than on 360cookware.com itself.
