Is PSB1416 Rectangular Pizza Baking Stone non-toxic? What it is made of
The PSB1416 is a ceramic or stone baking surface, meaning it is a fired clay or mineral composite with no applied non-stick coating, glaze overlay, or enamel finish. This material design eliminates the primary failure modes of coated cookware, Teflon-type coating off-gassing, lead or cadmium in glazes, and coating flaking into food. Ceramic and unglazed stone are thermally stable and do not leach metals or organic compounds into food under normal baking temperatures (up to 450-500°F for most pizza stones).
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.
Thermal fracture and ceramic fragmentation
Ceramic and stone baking surfaces are inherently brittle and can crack or shatter if exposed to rapid temperature changes or physical impact. Fragments present a choking and dental hazard if they enter food or the mouth.
Microcrack development and porosity over time
Repeated thermal cycling may cause micro-fractures in ceramic that trap food residue and moisture, creating hygiene concerns rather than direct chemical hazards. Regular inspection and timely replacement minimize this risk.
What’s reassuring
Bare uncoated material
Recorded as a bare, uncoated material with no surface coating or treatment.
Lead
The PSB1416 is described as bare ceramic or stone with no applied glaze overlay. No glaze-based safety issues are on record for American Metalcraft pizza stones in this category.
Source, ATSDR ↗Aluminum leaching
This product is ceramic or stone, not aluminum. Aluminum leaching does not apply to this material.
Teflon-type coating fume risk or coating degradation
No non-stick coating (Teflon-type coating or other) is applied to this pizza stone. Fume risk and coating flaking hazards do not apply.
How is this PFAS grade calculated?
The brand's record and disclosure
American Metalcraft is a long-established U.S. cookware and bakeware manufacturer with no widely documented safety recalls or controversies specific to ceramic baking stones. The brand does not publicly disclose PFAS testing or certification statements for this product line, which is consistent with the absence of PFAS-relevant coatings. No third-party certifications (NSF, FDA special status) are on record for this model, but absence of certification does not indicate a hazard.
How it compares in its category
Uncoated ceramic and stone pizza stones are lower concern than metal baking pans with non-stick coatings, which carry Teflon-type coating fume and degradation risks. They are comparable in safety to cast iron and stainless steel baking surfaces but do not require seasoning or metal leaching assessment. The trade-off is durability, ceramic and stone are brittle and prone to cracking if thermally shocked or dropped, which is a handling risk rather than a chemical hazard.
If you buy it
Preheat the stone gradually (place it in a cold oven and raise temperature slowly) to minimize thermal shock and cracking. Do not immerse it in water; wipe clean with a dry cloth or soft brush after cooling completely. Avoid sudden temperature changes, such as placing a cold stone on a hot surface or vice versa. Replace if cracks develop, as fracture can release ceramic fragments into food and pose a choking or dental hazard.
