3-LAYER ENAMEL COATING: Lava cast iron dutch oven has been coated with 3 layers of enamel with 3 stages of firing technique. Primer layer protects the product against corrosion, gives resistance to high temperatures and thermal shock, the 2nd layer enamel gives high scratch and wear resistance and creates a flavor layer, 3rd layer enamel makes a smooth, attractive surface that is easily cleaned and adds a perfect elegance in presentation. PROTECTIVE GLASS ENAMEL: The cooking surface of this cast iron sauce pan is glass enamel. Since this enamel shows the properties of glass, it has a transparent color, so the inner surface preserves its original casting color. Glass is a natural and a non-toxic coating that will protect the surface and maintain it for longer periods of time. Not only it makes this cookware versatile and easy to use but also gives a smooth and shiny surface that is both easy to clean and requires no seasoning before use. HEAT RETENTION: This sauce pan has 3-qt. capacity and it weighs 4 pounds with the lid. Its slow heat distribution and strong heat retention make it great for medium and low-heat cooking, from slow-cooking meats to roasting vegetables to boiling pasta, deep-frying, poaching, and almost any other cooking task you can think of. The smooth interior makes sure that everything inside is cooked evenly, and it releases food easily. It can be used on all kitchen stovetops (except the microwave), and it's oven safe to 500 degrees F. PRESERVES VITAMIN&AROMA: The special design lid offers a unique feature. Spikes on the Lava lids create a self-basting system, where the lid's spikes, flatness, weight and tight fit create a perfect environment for steam to rise, condense, and evenly drip back for more tenderness and flavor. This makes your food juicy, tender, and more flavorful. HOW TO CLEAN LAVA ENAMELED CAST IRON: Although Lava enameled cast iron is dishwasher safe, hand washing with warm soapy water and a nylon scrub brush is recommended to preserve the cookware's original appearance. Always dry cookware thoroughly and replace pot protectors between the rim and lid before storing in a cool, dry place. To remove stubborn baked-on food, boil 2 cups of water and 4 tablespoons of baking soda. Boil for a few minutes, then use a pan scraper to loosen the food
