Fat Daddio's Silicone Hemisphere
Lower concern. Silicone baking molds typically PFAS-free.
Fat Daddio's silicone hemisphere is a food-grade silicone mold with no reported PFAS concerns. Silicone baking tools are inherently lower risk than nonstick coated cookware.

The full breakdown
What it's made of and why it matters
Fat Daddio's silicone hemisphere is food-grade silicone, a synthetic polymer with Si-O backbone that does not contain the heavy metals, ceramic glazes, or non-stick coatings (like Teflon-type coating) common in other bakeware. Silicone is thermoset plastic, meaning it does not soften or leach monomers at normal baking temperatures (up to 500°F typical). The inert chemistry of cured silicone is why it avoids many hazards that plague ceramic, metal, or Teflon-type coating-coated cookware.
The brand's record and disclosure
Fat Daddio's is a United States-based baking mold manufacturer with a 20+ year track record in the silicone bakeware niche. The brand does not publish third-party testing results or formal safety certifications on their website; marketing emphasizes food-grade silicone and FDA compliance but does not detail manufacturing standards, heavy metal testing, or PFAS screening. No significant recalls or safety controversies tied to this product line are documented in public records.
How it compares in its category
Silicone molds eliminate hazards intrinsic to ceramic (lead/cadmium in glazes), metal (aluminum leaching, rust), and Teflon-type coating-coated pans (fume risk above 500°F). Compared to reusable glass or stainless steel hemisphere molds, silicone is more flexible, non-breakable, and easier to demold. The trade-off is durability: silicone degrades over years of high-heat use and repeated contact with oils, whereas metal lasts indefinitely.
If you buy it
Hand wash or use low dishwasher cycles to extend silicone life; high heat in the dishwasher accelerates breakdown. Do not exceed 500°F oven temperature. Replace the mold if you observe permanent discoloration, odor, stickiness, or tearing, as these signal polymer degradation. Store in a cool, dry place away from direct sunlight, which degrades silicone over time.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Silicone degradation over time
Silicone molds lose elasticity and may develop odor or staining after 3-5 years of frequent use, particularly with high-fat foods. No toxicological consequence is documented, but degraded silicone may shed small particles; replacement is recommended.
Leaching from pigments (if color-dyed silicone)
Fat Daddio's hemispheres are typically clear or opaque white. If pigmented versions exist, no testing records or complaints of color migration into food are on record. Food-grade colorants are theoretically safe but manufacturers rarely disclose pigment identity.
Mold or bacterial growth (storage)
Silicone retains moisture and can harbor mold if stored damp. This is a hygiene issue, not a manufacturing defect; ensure molds are completely dry before storage.
Lead or heavy metals in silicone matrix
Food-grade silicone is not formulated with lead or cadmium. No recalls or test failures for this hazard in Fat Daddio's products are documented.
Coating or finish degradation (N/A for solid silicone)
Unlike enameled or non-stick cookware, silicone has no coating to chip or peel. The polymer itself is the functional material, so coating failure is not a risk.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
