HexClad PATENTED TECHNOLOGY: The hexagon design is created through a laser etching process to provide both stainless steel and non stick surface. This dual surface allows your large wok sear still while using less oil, grease, and butter.WHY CHOOSE HexClad: Featuring a patented laser-etched hexagon design and tri-ply construction, HexClad is PFOA-free, oven safe up to 500 degrees, stovetop, and induction range-ready. It features stay-cool handles for a premium cooking wok experience.HIGH-QUALITY MATERIALS: To create a durable kitchen set that is built to last requires a tri-ply construction. The first and third layer are stainless steel for a sturdy nonstick inner and outer build, with aluminum in between to conduct consistent, even heat.EASY CLEAN & SCRATCH RESISTANT: The HexClad 12" big wok is dishwasher safe and can be cleaned using scorching or steel wool pads since it is scratch-resistant and won’t scuff or wear down from the use of metal utensils.SEASONING INSTRUCTIONS: It is imperative to season your HexClad cookware to get the non-stick cooking experience. To properly season your HexClad cookware, bring the cookware to medium-low heat and spread 1 teaspoon of vegetable oil around the interior. Your cookware will be ready for use after leaving it on heat for 2-3 minutes and will perform better over time as it re-seasons itself from the fats in the food you cook with.PROPER CARE AND USE: Wash cookware with warm soapy water before first use. The patented HexClad design allows heat to be distributed faster, so we recommend cooking on medium-low heat for most foods and medium to medium-high heat when searing meats.LIFETIME WARRANTY: HexClad's products are created to last a lifetime. Our cookware is backed by a lifetime warranty from manufacturer’s defects. With HexClad in your kitchen, you can be confident that your cookware will look beautiful and perform well for a long time.
