Non-stick cookware has been found to contain chemicals known as PFAS (per- and polyfluoroalkyl substances), which can cause health issues if ingested. PFAS are used in non-stick cookware to prevent food from sticking to the pan, but they can also be released into the air and ingested if the coating is scratched or overheated. To avoid exposure to PFAS, some people opt for ceramic pans, which are marketed as a safer alternative to traditional non-stick cookware. Ceramic pans are made without PFAS and provide a natural non-stick surface, but are they truly PFAS-free?

Ceramic pans are PFAS-free because they are made without PFAS chemicals
Ceramic cookware, on the other hand, provides a natural non-stick surface without the use of toxic chemicals in its production. It is made primarily of silicon dioxide and other metal oxides, not PTFE or any other PFAS. This means that ceramic pans are safer to use and less likely to release harmful chemicals, even when overheated. They also have a higher heat tolerance than traditional nonstick coatings.
The safety of ceramic cookware has been confirmed by experts. Lee Ferguson, PhD, an environmental analytical chemist and associate professor at Duke University, states that "Ceramic pans, those should be [PFAS] free." Gillian Z Miller, PhD, a senior scientist at the Ecology Center, agrees, noting that ceramics are made without PTFE or any other PFAS.
In addition to being PFAS-free, ceramic cookware offers several other advantages. It is less prone to chipping and has higher-quality non-stick properties, making it easier to clean and ensuring a longer lifespan for the cookware. It is also induction-compatible and safe at higher temperatures, making it a versatile option for various stovetops and cooking situations.
Overall, ceramic pans are PFAS-free because they are made without PFAS chemicals, offering a safer and more durable alternative to traditional nonstick cookware.

PFAS-free ceramic pans are safe to use and do not release harmful chemicals when overheated
Ceramic pans are a safe alternative to traditional non-stick pans, which have a reputation for containing toxins. PFAS-free ceramic pans are safe to use and do not release harmful chemicals when overheated.
PFAS, or per- and polyfluoroalkyl substances, are a group of chemicals that have been used in consumer products since the 1940s. They are found in many everyday items, including non-stick cookware, stain-resistant furniture, waterproof clothing, and cosmetics. Exposure to PFAS has been linked to liver damage, lowered immunity in children, and other health concerns.
When cooking with non-stick cookware that contains PFAS, there is a risk of ingesting the chemicals if the coating gets scratched or flaked off. Additionally, when some non-stick coatings, such as Teflon, are heated above 570°F, they begin to break down and release toxic chemicals into the air, which can then be inhaled.
Ceramic pans, on the other hand, provide a natural non-stick surface without the use of toxic chemicals. They are primarily made of silicon dioxide and other metal oxides, not PTFE or any other PFAS. Tests conducted by Consumer Reports on two ceramic-coated pans, the Always Pan and the Red Copper pan, did not detect any of the 96 PFAS they looked for.
PFAS-free ceramic pans are also less prone to chipping and have a higher heat tolerance than traditional non-stick coatings. They are easy to clean and maintain, as food is less likely to stick to the pan. Overall, PFAS-free ceramic pans are a safe and healthy option for cookware, providing peace of mind for those concerned about the potential health risks associated with PFAS exposure.

PTFE-free claims on non-stick pans are more meaningful than PFOA-free claims
The safety of non-stick cookware has been a topic of debate for the past decade, with health agencies raising concerns about the compound PFOA, which was previously used to make Teflon. While PFOA has been phased out of production in the US and is no longer used in the manufacturing of non-stick pans, it has been replaced by another PFAS, GenX, which likely has the same positive and negative properties as PFOA.
This is where PTFE-free claims come in. PTFE, or polytetrafluoroethylene, is the chemical name for Teflon and is in the PFAS category. While PTFE is generally considered safe and non-reactive in the human body, it can break down at high temperatures, releasing toxic chemicals into the air and food. This is especially concerning for people with pet birds, as even small amounts of PTFE fumes can be deadly for them.
When shopping for non-stick cookware, it is important to look for products that are PTFE-free, as this indicates that the pan is not coated with Teflon or a Teflon-derivative. Ceramic pans are a popular alternative to PTFE-coated pans and are often marketed as PTFE-free. Ceramics are primarily made of silicon dioxide and other metal oxides, not PTFE or any other PFAS, according to Gillian Z Miller, PhD, a senior scientist at the Ecology Center.
While PFOA-free claims are also common, they are less meaningful than PTFE-free claims. This is because even products made without PFOA may contain the compound due to the manufacturing process. Tests on PTFE-coated pans that were claimed to be PFOA-free found measurable amounts of PFOA and other PFAS. Therefore, consumers who want to avoid PFAS in their non-stick cookware should focus on products that claim to be PTFE-free, such as ceramic-coated pans.

Ceramic pans are less prone to chipping and are therefore safer than traditional non-stick pans
Ceramic pans are a safer alternative to traditional non-stick pans. They are less prone to chipping and therefore do not cause the same toxic issues as traditional non-stick pans. Traditional non-stick pans are coated with polytetrafluoroethylene (PTFE), which is part of the per- and polyfluoroalkyl substances (PFAS) family of chemicals. When these pans are overheated, they can release toxic fumes, and if their coating is scratched, it can flake off into food and be ingested.
Ceramic pans, on the other hand, are primarily made of silicon dioxide and other metal oxides, not PTFE or any other PFAS. They provide a natural non-stick surface without the use of toxic chemicals in their production. They are less prone to chipping due to their super-hard, textured surface, which is created by fusing plasma ceramic particles to the pan at an extremely high temperature. This results in a stronger bond between the coating and the pan, reducing the likelihood of chipping.
The non-stick properties of ceramic pans are also higher in quality, reducing the need for excessive scrubbing that can lead to chipping in traditional non-stick pans. This further prevents the release of toxic chemicals into food. While ceramic pans may not be as effective as traditional non-stick materials, their reliability and safety make them a preferred choice for many.
It is important to note that while ceramic pans are marketed as PFAS-free, it is theoretically possible that they may contain other PFAS that were not detected in tests. However, the absence of commonly used PFAS, such as PTFE and PFOA, makes ceramic pans a safer option.
To summarise, ceramic pans are less prone to chipping due to their durable construction and superior non-stick properties. This makes them a safer alternative to traditional non-stick pans, which can release toxic chemicals when chipped or overheated.

PFAS exposure has been linked to liver damage, lowered immunity in children, and other health concerns
Ceramic pans are generally PFAS-free. PFAS, or per- and polyfluoroalkyl substances, are man-made chemicals that are widely used in consumer and industrial products. They are sometimes called "forever chemicals" because they break down very slowly and accumulate in the environment and in human tissue, including the liver. PFAS exposure has been linked to liver damage, lowered immunity in children, and other health concerns.
PFAS exposure has been linked to liver damage through its ability to interfere with hormone systems and mimic fatty acids. This can lead to fat accumulation or inflammation in the liver, similar to the effects of an unhealthy diet. Animal studies have shown that PFAS exposure is associated with abnormal accumulation of fat in the liver, although the same conclusion has not yet been definitively reached for humans due to a lack of biopsy-confirmed data. However, researchers have found that PFAS exposure is largely correlated with an increase in enzymes that indicate liver disease, specifically non-alcoholic fatty liver disease (NAFLD). This disease is characterized by a build-up of fat in the liver and affects about a quarter of the world's population.
PFAS exposure has also been linked to lowered immunity in children. Studies have suggested a link between maternal PFAS blood serum levels and reduced antibody production following inoculation in children. Specifically, there is an association between PFAS exposure and decreased tetanus and diphtheria antibodies across different age groups. Prenatal exposure to PFAS has also been associated with lower antibody titers against rubella in early childhood, indicating an immunotoxic effect.
In addition to liver damage and lowered immunity, PFAS exposure has been linked to other health concerns. These include thyroid and heart disease, developmental deficiencies, certain cancers, and cholesterol, triglyceride, and uric acid issues, which are additional biomarkers of metabolic disruption. PFAS are also associated with endocrine disruption, which can lead to metabolic changes and the development of fatty liver.
While ceramic pans are PFAS-free, it is important to note that other non-stick cookware may contain PFAS or similar chemicals, such as PFOA, which can be toxic if ingested. Therefore, it is recommended to use non-toxic, non-stick cookware that is free of PTFE, PFOA, and PFAS.
