Zeal has put all their knowledge and experience into spreading the joy of cooking - developing innovative products that bring speed ease and fun into your kitchen. For People who love cooking as much as we do. The joy of a beautiful product begins with a touch, so the material quality and finish must be as considered and selective as the design and functionality. Zeal developed their own silicone material 7 years ago which is odorless. Silicone before always had a chemical smell to it and most cheap silicones still do now. Zeal silicone is EEC approved which is a far higher standard for food contact than the FDA requirement for quality of silicone. In fact, FDA silicone quality would not pass an EEC food contact test. The real problem for silicone is when it comes into contact with hot oils and other hot substances. Inferior silicone will leach into food. Zeal silicone does not and it also stands up to high temperatures of food contact. TThe Flower Lid creates a tight seal on all smooth rims, be it stainless steel, glass, plastic, or melamine.
