Parchment paper is generally considered safe for everyday cooking, provided it is used within its temperature limits. However, specific health and chemical concerns have sparked debates around certain types.
Parchment paper can pose toxicity concerns depending on how it is manufactured and the coatings applied to it. The primary risks stem from three specific factors:
While some baking papers are coated with Quilon, which contains heavy metals like chromium that can be toxic when incinerated, If You Care Parchment Paper uses Silicone, derived from a natural element. It's a much more expensive process, but one we feel is worth it for everyone.
Parchment paper can pose health, safety, and environmental issues, primarily because of how it is manufactured and used.
Although parchment never stopped being used (primarily for governmental documents and diplomas) it had ceased to be a primary choice for artists' supports by the end of the 15th century Renaissance. This was partly due to its expense and partly due to its unusual working properties.
Yes, parchment paper is generally considered less toxic than aluminum foil. Because it is made from processed cellulose, it is chemically inert and doesn't leach metals or chemicals into your meals.
Yes, authentic parchment (and vellum) is still made from animal skin. However, it is important to distinguish this historical writing material from the "parchment paper" you use in the kitchen.
PFAS-free parchment paper is designed to handle high-heat baking without releasing "forever chemicals". Reputable brands rely on natural silicone (derived from sand and quartz) or sulfuric acid treatment rather than toxic coatings to achieve their non-stick properties.
They stopped making true tin foil in the 1940s because aluminum was cheaper, lighter, more durable, and—crucially—did not leave a metallic aftertaste on food. Although true tin foil hasn't been produced for nearly a century, the name "tin foil" stuck around out of habit.
The best everyday parchment paper substitute for baking is aluminum foil lightly coated with butter or cooking spray. For cooking or roasting, a simple coating of oil straight on the pan will work perfectly.
To avoid toxic chemicals like PFAS, chlorine bleach, and heavy metals, switch to certified non-toxic, unbleached parchment paper. These alternatives use natural silicone (derived from sand) for non-stick properties and are totally chlorine-free.
King Arthur Unbleached Parchment Paper is designed to be PFAS-free. Instead of relying on PFAS, it uses a high-quality silicone coating that is considered safe for standard baking applications.
Parchment paper is a well-loved kitchen essential for professional and home chefs and bakers alike.
Most traditional parchment paper does not contain traditional plastics, but it is coated with silicone, which is a synthetic polymer. Additionally, some brands treat their paper with PFAS ("forever chemicals") to provide extra grease resistance.
You can use either side of most parchment paper, as both sides are typically coated with non-stick silicone. However, if your paper has a noticeable difference in texture, face the shiny, slick side up against your food.
You can typically reuse a single sheet of parchment paper 3 to 4 times. Its lifespan depends entirely on the baking temperature and what you are baking.
Accordingly, our kitchens must be kashered (“kosherized”). Things that can't be koshered must be put away or (wait for it…) covered. If you visit different houses, you may notice different things covered or uncovered.
People put foil on doorknobs as a viral, low-tech alarm system. The crinkling foil is intended to make a loud noise if someone tries to turn your handle, or to show visible signs of tampering (like ripped or missing foil) to alert you that someone tried to get in.
People often put aluminum foil in the toilet tank as an internet cleaning or plumbing hack, usually claiming it softens water, prevents rust, displaces water to save on utility bills, or freshens the bowl.
A common question is whether parchment paper is non-toxic, especially when heated. The answer is generally yes. The silicone coating on parchment paper is considered food-safe and non-toxic. Unlike other non-stick coatings, silicone does not release harmful chemicals when heated.
While there is no immediate medical treatment or magic pill to "flush" PFAS out overnight, your body eliminates them naturally over time through bodily functions like urination, sweating, and blood loss (such as menstruation).

To find PFAS-free parchment paper, look for unbleached, chlorine-free, and certified compostable brands. Independent testing identifies these top, non-toxic options that contain no intentionally added PFAS:
In occult and witchcraft traditions, parchment has long been revered as a sacred surface for transcribing intentions, spells, and affirmations. Its natural qualities are believed to amplify spiritual work, making it a foundational tool for rituals, spell jars, and talismans.
Whether for parchment or vellum, the animal skin was first soaked in a solution of lime to soften it and loosen the hair which was then removed. The skin was then stretched on a wooden frame where it was scraped with a curved knife called a lunellum.
