Material
borosilicate glass, bare uncoated
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Thermal shock and fracture
While borosilicate is designed for heat resistance, rapid temperature changes or exposure to extreme heat can cause cracking or shattering. This is a mechanical rather than chemical hazard but relevant to proper use of this specific product.
Edge chipping and glass fragments
Repeated washing, stacking, or contact with hard utensils can chip glass edges over time. Small glass fragments in food pose a physical injury risk and are the primary concern with glass cookware longevity.
What’s reassuring
Bare uncoated material
Recorded as a bare, uncoated material with no surface coating or treatment.
Lead
Borosilicate glass as a material class does not require lead or cadmium in its composition, and no recalls or test reports implicating this bowl for heavy metal leaching are on record. Standard borosilicate is considered lead-free.
Source, ATSDR ↗Coating degradation and leaching
This product is bare, uncoated borosilicate glass with no enamel, ceramic, or polymer finish, eliminating risks of coating wear, peeling, or leaching of adhesives or pigments.
Teflon-type coating or non-stick fume release
Glass has no Teflon-family coating or non-stick coating, so Teflon-type coating degradation and fume inhalation risks do not apply to this product.
The full breakdown
What it's made of and why it matters
This is a borosilicate glass bowl, a heat-resistant form of glass engineered to withstand thermal shock and mechanical stress. Borosilicate contains silica and boric oxide, which create a denser, more chemically inert material than standard soda-lime glass. Because it is uncoated bare glass with no enamel, ceramic, or polymer finish, there are no glazes or surface treatments that could degrade, chip, or leach contaminants into food during heating or repeated washing.
The brand's record and disclosure
Big Boss is a small kitchen appliance brand with limited public disclosure on safety testing, certifications, or material sourcing practices. No major recalls or safety controversies specific to this glass bowl model are on record. The brand does not prominently advertise third-party certifications (FDA, NSF, or independent lab testing) for cookware safety, which is common for budget-tier appliance manufacturers.
How it compares in its category
Borosilicate glass replacement bowls have lower concern regarding PFAS-related hazards, especially when uncoated. This avoids the risks of non-stick coatings (Teflon-type coating fume release, coating wear) and ceramic or enamel glazes (lead, cadmium, degradation). Compared to metal or ceramic air fryer baskets or bowls, bare glass has no surface finish to contaminate food and is chemically passive across typical cooking temperatures.
If you buy it
Use standard glass care, avoid rapid temperature changes (allow gradual heating and cooling to prevent thermal shock and cracking), hand wash or use gentle cycle to prevent edge chipping, and inspect regularly for hairline cracks that could expand during heating. Borosilicate glass is rated for oven and air fryer use up to around 500 degrees Fahrenheit; do not expose to direct flame or extreme temperature swings. Replace immediately if cracks, chips, or discoloration appear.
