Utilizing pure ceramic as a coating, the Green Earth Wok by Ozeri is one of the world's first frying woks to achieve non-stick perfection while remaining free of PTFE, PFOA, and other harmful chemicals. Conventional cookware and other ceramic cookware brands achieve their non-stick performance through a coating of PTFE (PolyTetraFluoroEthylene), a synthetic substance that has waxy properties. At very high temperatures, PTFE begins to decompose and release fumes that are documented to be lethal to birds and small pets, and which can be harmful to humans. In addition, traditional cookware incorporating PTFE is often manufactured with the aid of PFOA (PerFluoroOctanoic Acid), which the EPA has classified as a 'persistent pollutant of the environment. With the Green Earth Wok's cozier technology, even under high temperatures, such harmful toxic fumes are never released into the environment. This is because the Green Earth Wok by Ozeri utilizes a 100% ceramic coating inspired by nature. The Green Earth Wok's ceramic coating is completely free of PTFE and PFOA. In addition to being eco-friendly and ultra-safe, the Green Earth Wok's ceramic coating is far more durable and scratch-resistant than other non-stick surfaces. With better non-stick properties, the Green Earth Wok by Ozeri allows you to sauté, fry, bake, boil and braise with as little as half the amount of oil normally used, and it makes cleaning a breeze. The Green Earth Wok by Ozeri is made of the highest quality die-cast aluminum that allows for even cooking and fantastic browning without the risk of hot spots. It boasts a magnetized bottom for rapid heat transfer on induction stoves and a heat-resistant Bakelite handle. Your satisfaction is guaranteed.
