Great Jones Holy Sheet Ceramic Nonstick Half Sheet Pan Set of 2
Lower-concern choice; ceramic nonstick is generally safer than Teflon-type coating, though independent verification of the claim would strengthen confidence.
Great Jones's Holy Sheet pans use a ceramic-based nonstick coating and the brand claims PFAS-free formulation. Ceramic nonstick is a known lower-PFAS alternative to traditional Teflon-type coating, but the brand does not appear to hold third-party PFAS certifications. No public lab data or recalls flag concern.
Brand says: “Great Jones describes their Holy Sheet pans as featuring a ceramic nonstick surface and markets them as PFAS-free”

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
Brand-stated PFAS-free
The brand states the product is PFAS-free (self-declared).
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
The Holy Sheet uses a ceramic nonstick coating applied over what Great Jones describes as a steel substrate. Ceramic coatings are inorganic mineral-based systems that do not require fluorinated compounds (Teflon-type coating/PFAS) to achieve nonstick performance, eliminating the fume-release risk associated with traditional nonstick at high heat. The trade-off is that ceramic nonstick is generally less durable and more prone to chipping or gradual loss of nonstick properties over time, especially with metal utensils or abrasive scouring.
The brand's record and disclosure
Great Jones is a direct-to-consumer cookware brand that explicitly markets products as PFAS-free and has publicly committed to avoiding fluorinated nonstick coatings. The brand does not appear in FDA enforcement actions or major safety recalls related to cookware chemistry. However, publicly available independent third-party testing of Great Jones ceramic nonstick coatings is not widespread; the PFAS-free claim relies partly on material specification rather than published lab verification. The company provides care instructions but detailed coating composition disclosure beyond ceramic is limited.
How it compares in its category
Ceramic nonstick half-sheet pans occupy a middle ground: safer than Teflon-type coating cookware at high heat, but less nonstick longevity than seasoned cast iron or stainless steel. Compared to budget ceramic alternatives (often from overseas vendors with less transparent sourcing), Great Jones offers U.S.-based customer support and quality control oversight. Versus premium ceramic brands like GreenPan or Our Place, Great Jones pricing is competitive and positioning is similar, though those competitors may have more published third-party testing on coating durability and heavy metal absence.
If you buy it
Hand wash only; dishwasher use accelerates coating wear. Keep oven temperatures below 400F unless Great Jones explicitly certifies higher; ceramic coatings can degrade or off-gas if overheated. Use silicone, wood, or plastic utensils to avoid chipping the coating. Inspect regularly for cracks, flaking, or bare spots; once coating integrity is compromised, replace the pan to avoid potential substrate leaching. Store nested pans with a soft cloth between them to prevent friction damage.
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.”
Ceramic coating degradation and substrate exposure
Ceramic nonstick coatings wear faster than Teflon-type coating under normal use. If the coating chips or flakes, the underlying steel substrate becomes exposed; while food-grade steel is safe, loss of coating defeats the nonstick purpose and may trigger replacement sooner than expected.
Heavy metal leaching from substrate or glaze
No lead, cadmium, or other heavy metal contamination has been reported in Great Jones cookware products. Ceramic glazes from reputable U.S. manufacturers are typically tested for food-contact safety, but independent verification specific to this product line is not publicly available.
Thermal fume release at high temperature
Ceramic nonstick formulations do not rely on Teflon-type coating and thus do not release polymer fume at typical baking temperatures. However, overheating ceramic coatings beyond product specifications could theoretically trigger off-gassing; Great Jones does not widely publish full thermal stability data.
Aluminum substrate leaching
Great Jones specifies steel substrate for the Holy Sheet line, not aluminum, eliminating aluminum leaching risk. The ceramic coating provides a barrier between food and steel, which is not a known leaching hazard for food pH typical in baking.
Microplastics or polymer particulates from coating wear
Ceramic is mineral, not plastic, so true microplastic risk is absent. However, fine ceramic particulates could theoretically flake into food if the coating degrades significantly; this is rare but reinforces the importance of inspecting and replacing pans with visible damage.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
Formulations and coatings change between production runs. Always check the current label before buying.
