Fat Daddio's Silicone Bakeware Hemisphere 4 oz
Lower concern. Silicone bakeware lacks inherent PFAS risk.
Food-grade silicone is not Teflon-type coating and typically does not require PFAS treatment. No public evidence of PFAS in Fat Daddio's silicone products, though brand offers no explicit disclosure.

The full breakdown
What it's made of and why it matters
Fat Daddio's hemisphere bakeware is made of food-grade silicone rubber, a synthetic polymer that does not contain the ceramic glazes, metal coatings, or non-stick Teflon-family coating (Teflon-type coating) found in traditional cookware. Silicone is thermally stable and non-reactive across typical baking temperatures (up to 500-600°F), meaning it does not leach metals like aluminum or cadmium and does not degrade into harmful fumes during normal use. The material is chemically inert and inherently resistant to the coating degradation problems that plague enameled cast iron or non-stick skillets.
The brand's record and disclosure
Fat Daddio's is a silicone bakeware specialist with no public safety recalls, documented contamination incidents, or health complaints on record. The brand does not publish detailed chemical safety certifications or PFAS testing results, reflecting an industry-wide pattern of minimal transparency in silicone manufacturer disclosure. However, the absence of controversy does not indicate poor practice; it reflects that silicone bakeware is a lower-hazard category overall and Fat Daddio's maintains a stable market presence without safety incidents.
How it compares in its category
Silicone baking molds are safer than ceramic hemisphere molds (which may contain lead in glazes) and steel or aluminum alternatives (which can leach metals if uncoated). They eliminate Teflon-type coating non-stick fume risk entirely, unlike silicone-coated metal or traditional non-stick cookware. Fat Daddio's silicone products are comparable in safety profile to other established silicone bakeware brands and present no category-specific liability.
If you buy it
Confirm the bakeware is labeled food-grade silicone and store it away from direct sunlight and heat when not in use to prevent slow degradation of the polymer. Do not exceed 600°F (the typical silicone temperature ceiling). Inspect periodically for tears, discoloration, or odor; silicone can occasionally emit a faint rubbery smell early in use, which is normal and fades with washing. Hand wash or use mild dish soap; harsh detergents and abrasive scrubbers may accelerate surface wear over years of heavy use.
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 polymer degradation at extreme heat
No documented cases of Fat Daddio's hemisphere molds degrading or leaching chemicals at normal baking temperatures (below 600°F). Silicone is thermally stable in this range; risk is theoretical if used far beyond manufacturer specifications.
Residual volatile organic compounds (VOC) off-gassing during first use
New silicone bakeware may release a temporary rubber-like odor due to manufacturing residues; this is normal, fades rapidly with washing and use, and is not documented as a health hazard in food-contact silicone. No brand-specific reports exist.
Bacterial growth in crevices or damage
Silicone's non-porous surface resists bacterial colonization far better than porous ceramics or wood. Risk only materializes if the product is damaged, creating seams or tears where moisture can lodge; inspect before each use.
Lead or heavy metals in silicone formulation
Food-grade silicone does not inherently contain lead, cadmium, or antimony. No recalls or test findings link Fat Daddio's silicone products to heavy metal contamination. This hazard class is not a concern for this material.
Migration of silicone monomers or oligomers into food
Silicone can release trace cyclic oligomers into fatty foods when heated; regulatory bodies (FDA, EU) consider migration below detection limits safe for food contact. No brand-specific testing data is public, but silicone is presumed safe by consensus in food contact applications.
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.
