There is a steaming hot bowl of fresh soup on the table, which often makes people salivate. To make soup more delicious, it not only depends on the craftsmanship, but also on choosing a good soup pot. Some people think I'm just cooking soup with a frying pan. This idea is incorrect.

Milk jug is mainly used to heat milk. Milk cans can eliminate bacterial infections in milk while preserving the nutritional value of the milk itself. Therefore, milk pots can also be used to heat desserts and soups. You can cook some simple Congee and pasta.

1. Cast iron
Due to poor ductility, the cast iron pots and kitchen knives we see are very 'heavy'. In addition, the thermal conductivity of cast iron is insufficient, but its heat storage performance is good. This is even harder to understand. But cast iron pots are not useless. Cast iron pots have a wide range of uses and can be used for stewing and stewing. When making food, ingredients can be heated evenly and are sturdy and durable. However, cast iron pots are also prone to rusting an

Different materials have different thermal conductivity. The thermal conductivity of some materials we often use is: iron 80 (W/mK), cast iron 40 (W/mK), stainless steel 15 (W/m potassium), glass 1 (W/mK), ceramics<1 (W/mK -), copper 398-401 (W/mK -), aluminum 237 (W/mK -). Their specific heat capacities are: iron 0.442 (KJ/kg-K), cast iron 0.503 (KJ/kg/kg-K), stainless steel 0.465 (KJ/kg-K "), glass 0.75 (KJ/kg-K), ceramic 0.85 (KJ/kg-1), copper 0.386 (KJ/kg-K), and aluminum 0.905 (KJ/kg-K).
