Compatible Cookware There are many induction quality pots and pans on the market, however, the most compatible pans for the Invisacook are a full clad stainless-steel, thick magnet bottom pan, and Invisacookware. Non Compatible: Aluminum, all-copper, or glass cookware will not work unless they have a layer on the bottom with magnetic properties. Many manufacturers have started adding a magnetic layer to the bottom of those types of pots and pans; however, it can be very thin and will take longer to heat up than a high-quality induction pan. NOTE: Cast Iron pans are induction, however, they do get extremely hot due to the content of metals within them, and reflect a large amounts of heat, which over time will not be good for your countertop. Invisacook asks that you don’t use this type of cookware when using the Invisacook. Testing for Compatibility To tell if a pot or pan is compatible with your induction stove, hold a magnet to the bottom. If the magnet clings to the underside, the cookware will work on an induction cooktop. If the magnet grabs the pan softly, you may not have good success with it on your cooktop. If there is no pull on the magnet, it doesn’t contain the right metals and will not generate heat. Note: Many manufacturers have started putting an “induction compatible” symbol on the bottom of their cookware or note compatibility on the packaging. The symbol often looks like a horizontal coil.
