Visions Amber 3.5L glass pot is made of glass ceramic ( Pyroceram ) with a glass lid. Pyroceram is a completely harmless glass ceramic material that does not release toxic substances when heated, is non-porous, does not absorb odors or flavors from food, and is not reactive to acidic foods. It also does not contain heavy metals such as chromium or nickel. Characteristics: Materials: glass Capacity: 3.5 liters Contents: Vitroceramic pot and glass lid Measurements (height/diameter): 15.5 x 21 cm The Visions® glass ceramic pot is highly resistant to sudden changes in temperature. It can even be taken directly from the refrigerator to the oven, stove or microwave, and then to the dishwasher or sink, no matter how hot or cold the pot is. It can be used on electric, gas or glass ceramic cooktops, although not on induction cooktops. The glass ceramic in Visions® pots retains a lot of heat, which allows you to cook over a lower heat setting, thereby saving energy. In addition, by cooking over a low heat, you prevent food from sticking or burning, and the nutrients in the food are better preserved. You can monitor the cooking process at all times without having to lift the lid of the pot, since the glass ceramic is a completely transparent material. Visions® cookware is easy to clean, does not stain or retain odors as happens with containers made of other materials. It is dishwasher safe. Using Visions Products: Visions products are not non-stick. For optimal use, it is recommended to heat over a low heat for about two minutes before cooking and using preparations with liquids or fats. If any food has stuck to the base, soak it in hot water for a while before cleaning. Always wash with a sponge or soft scouring pad.
