Where these two actually differ
- We flag Glaze degradation and surface leaching, Thermal stress fracture and Microporosity and microbial retention on the and not on the Williams Sonoma.
- We flag PTFE fume risk and thermal degradation, Coating degradation and microflaking and Unspecified fluorine-based chemistry (PFAS adjacency) on the Williams Sonoma and not on the .
- The is Ceramic (clay-based baking stone) where the Williams Sonoma is Carbon steel with proprietary nonstick coating (unspecified composition), which is most of the difference in these two grades.
- The gap is 75 points, wide enough that this is not a close call, and the is the one to buy.
- We are less certain about the Williams Sonoma grade, at 42% confidence against 82%, because it discloses less.
