Fat Daddio's Silicone Bakeware Hemisphere
Lower concern. Food-grade silicone is not a material linked to PFAS.
Material as recorded is food-grade silicone, which is not a material linked to PFAS. No water-repellent finish or coating is on record for this product. The brand has no PFAS statement on record.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Silicone polymer degradation and leaching at high heat
While food-grade silicone is stable under normal baking, prolonged exposure above manufacturer ratings or repeated heating near upper limits can cause silicone chains to break down. No established health endpoint from minor silicone oligomer leaching exists in regulatory literature, but degradation is a documented aging mechanism.
Lead
Silicone molds can tear with mishandling or become brittle with age. Once compromised, small particles may enter baked goods. Risk is low if product is inspected regularly and discarded when damaged, but material brittleness is an inherent aging mechanism.
Source, ATSDR ↗Mold or bacterial colonization in crevices if improperly cleaned
Silicone texture can trap residue in microscopic grooves if not dried thoroughly after washing. This is a cleaning and storage issue, not a manufacturing defect, but silicone's texture makes it more prone to residue retention than smooth metal.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Leaching from colorants or additives in silicone formulation
Food-grade silicone used by reputable suppliers typically excludes toxic dyes and heavy-metal pigments; Fat Daddio's products show no safety recall history related to colorant leaching. However, brand does not publish detailed additive disclosure, so assurance is indirect.
Aluminum substrate leaching (if applicable to this model)
Fat Daddio's Hemisphere is pure silicone with no metal substrate, so aluminum leaching does not apply. This is a safety advantage over hybrid bakeware designs.
The full breakdown
What it's made of and why it matters
Fat Daddio's Hemisphere is molded food-grade silicone, a synthetic rubber polymer that does not require nonstick coatings or glazes to function. Unlike ceramic-coated or enameled bakeware, silicone baking molds eliminate coating-degradation pathways entirely. The material is chemically inert across normal baking temperatures (typically rated to 400-500°F) and does not leach from surface wear, scratches, or age-related breakdown the way glazed cookware can.
The brand's record and disclosure
Fat Daddio's is a specialized baking-equipment supplier with no published safety controversies or major recalls involving their silicone bakeware. The brand does not publicly disclose third-party certifications (e.g., FDA compliance statements or independent polymer testing) on product pages, which is common in this price tier but limits transparency. No established data links Fat Daddio's silicone products to adverse health reports.
How it compares in its category
Silicone baking molds avoid the lead/cadmium glaze risk of ceramic hemisphere molds and the Teflon-type coating fume risk of nonstick metal alternatives. They sit midway between reusable metal pans (which require grease and wear) and single-use parchment (which avoids leaching entirely but generates waste). Silicone's main trade-off is durability, it degrades with prolonged heat exposure and can tear, whereas metal is indefinite.
If you buy it
Hand-wash only; dishwashers can accelerate silicone degradation and staining. Do not exceed the manufacturer's stated heat ceiling (check packaging; typically 400-500°F). Inspect for tears, brittleness, or permanent discoloration every 1-2 years; replace if the material becomes rigid or flakes. Store flat or rolled loosely to prevent permanent creasing, which can compromise structural integrity over time.
