Advantages: fast heat conduction, even heating and good insulation. Although the preheating of an enamel pot is slower than that of a regular pot, it maintains a stable heat level after preheating is complete and can be maintained with a very small flame. The pot also retains heat for a long time after the heat is turned off. The pot is thick and has a good seal.

Disadvantages: It is heavier than normal pots and pans, and the lid will be so tight that you can't hear a single movement in the pot, even when cooking, so it's not very easy to judge the heat.

Enamel pots and pans are mainly composed of high-strength quartz and feldspar and other silicate minerals, which have no toxic side effects on the human body. Enamel enameling on the metal surface prevents the metal from rusting, keeps the metal from forming an oxidized layer on the surface when it is heated, and resists the erosion of various liquids.

So in the use of enamel pot cooking food process, not because of the high temperature and produce harmful dissolved matter, and resistance to acid and alkali ability is good, will not and food chemical reaction. Cast iron cookware is composed of iron and carbon, the natural cast iron material is heavier than the general metal material, is recognized as the best quality cookware material.
