Ovens retain heat by utilizing insulation. The insulative coverings help prevent thermal conduction through the walls of the oven.
to conserve heat
Microwave ovens cook faster because they use electromagnetic waves that penetrate food and heat it directly, whereas traditional ovens rely on convection and conduction, which take longer to transfer heat to the food. This allows microwave ovens to heat food more rapidly and efficiently.

Ovens
Most ovens do not use fire, they simply heat up the air with electricity.
yes.
Ovens do not actually use radiation to heat food. "Ordinary" ovens simply use a high-resistance material as a heating element, which, when an electric current is run through, discharges a large amount of heat.
No, microwave ovens do not emit ultraviolet (UV) radiation. They use microwave radiation to heat and cook food by causing water molecules in the food to vibrate, generating heat. UV radiation is not involved in the operation of microwave ovens.
Stainless steel ovens are great for insulation, as they can easily absorb plenty of heat.
Their is no optimum heat setting for pizza ovens to acheive the perfect crust. Cooking time can be adjusted with temperature to acheive the desired crust.
There are no radioactive materials in microwave ovens: they use microwaves to cook food and heat liquids.
An oven can be used for baking or cooking at relatively high, dry, heat. Many ovens also allow broiling or cooking under a high flame or heat.
