Fat Daddio's Hemisphere Silicone Baking Mold
Lower concern. Food-grade silicone is not a material linked to PFAS.
Material as recorded is food-grade silicone elastomer. The brand has no PFAS statement on record. Silicone in this product category is not a material linked to PFAS.

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.
Microplastic shedding
Prolonged use, mechanical wear, or exposure to sharp utensils or acidic foods may cause microscopic silicone particles to shed into baked goods. Risk is low under normal use but increases with age and scratching; inspect for visible damage before each use.
Mold or bacterial colonization
If not dried thoroughly after washing or stored in damp conditions, silicone's porous surface texture can harbor residual moisture that promotes mold growth. Ensure complete air-drying and store in a dry location.
Surface discoloration or staining
Fat Daddio's silicone molds may absorb color from batter (especially red velvet, beets) or develop brownish stains over time from heat exposure. This is cosmetic and does not indicate chemical degradation or safety failure.
Permanent deformation or tearing
Silicone molds can permanently warp, crease, or tear if twisted, overfilled, or stored improperly. Once torn, they should be replaced to avoid fragments contaminating food and to prevent bacterial trapping in the crack.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Silicone leaching or degradation
No established recalls or published toxicology studies document harmful leaching from food-grade silicone molds at normal baking temperatures. Silicone is designed to resist chemical breakdown and remain stable in the oven environment.
The full breakdown
What it's made of and why it matters
Fat Daddio's Hemisphere molds are made from food-grade silicone elastomer, a synthetic polymer that does not contain the ceramic glazes, enamel coatings, or metal substrates that trigger lead, cadmium, or aluminum leaching concerns in traditional cookware. Silicone is chemically inert at normal baking temperatures (up to around 500F) and does not degrade into particles or toxic fumes under typical home-use conditions. The material is FDA-cleared for food contact, meaning it meets basic non-migration standards for regulated additives.
The brand's record and disclosure
Fat Daddio's is a US-based baking-supply manufacturer with no public recalls, safety warnings, or disclosed controversies tied to silicone mold products. The company does not prominently advertise third-party certifications (such as NSF or independent toxicology reports) on this product line, nor does it disclose detailed ingredient composition or PFAS testing. This silence on PFAS is typical for the silicone bakeware category but leaves some uncertainty; however, absence of documented PFAS use in silicone molds is the industry norm.
How it compares in its category
Silicone molds show lower concern for leaching and degradation compared to metal-based pans, glazed ceramics, and non-stick coatings. They are superior to single-use plastic molds (which can shed microplastics if heated) and reusable plastics that may contain BPA. Compared to traditional aluminum or steel molds, silicone eliminates metal ion migration and coating failure over time, though it is less durable and more prone to tearing or permanent deformation.
If you buy it
Use the mold on standard baking sheets or directly in a 500F oven; do not exceed the manufacturer's stated temperature limit. Hand-wash in warm soapy water or top-rack dishwasher; avoid prolonged contact with oils or fats at high temperature, which can cause slight surface stickiness over years of use. Inspect annually for tears, permanent creasing, or discoloration that signals material breakdown. Replace if cracks develop, as they can trap bacteria and food residue. Store flat or hanging to prevent permanent deformation.
