How to Choose Between Pig Iron Pot and Wrought Iron Pot?

Many people like to cook in an iron pot.

They think they are healthy and can supplement iron.

In fact, it has not been decided whether they can supplement iron, but there are many benefits of an iron pot, otherwise, they won’t have such a good reputation.

Today we are not talking about the benefits of an iron pot, but the difference between pig iron pot and wrought iron pot.

Is it better to buy pig iron pot or wrought iron pot?

Iron can be divided into pig iron and wrought iron, which means that the carbon content of wrought iron decreases after various heating, resulting in an increase in hardness.

The difference between pig iron and wrought iron lies in the carbon content.

The carbon content of pig iron is higher and that of wrought iron is lower.

Pig iron generally refers to the alloy of iron with a carbon content of 2~4.3%.

Also known as cast iron.

In addition to carbon, pig iron also contains silicon, manganese and a small amount of sulfur and phosphorus.

It can be cast but not forged.

According to the different forms of carbon in pig iron, it can be divided into steelmaking pig iron, casting pig iron, nodular cast iron and alloy pig iron.

Alloy pig iron contains silicon, manganese, nickel or other elements and is often used as raw material for steelmaking.

Adding some alloy pig iron in steelmaking can improve the properties of steel.

Steelmaking pig iron

The carbon in steel-making pig iron mainly exists in the form of iron carbide, and its section is white, which is usually called white iron.

This pig iron is hard and brittle. It is generally used as raw material for steelmaking.

Cast pig iron

Cast pig iron has good cutting, wear-resistance and casting properties because of its soft graphite and lubrication.

However, its positional strength is not enough, so it can not be forged and rolled, and can only be used to manufacture all kinds of castings.

Nodular cast iron

The carbon in nodular cast iron exists in the form of spherical graphite. It has excellent casting, cutting, elasticity and wear resistance.

It is widely used in the manufacture of high-grade castings such as crankshaft, gear, piston and a variety of mechanical parts.

Iron Pot

Is it better to use pig iron or wrought iron for the frying pan?

Advantages and disadvantages of pig iron pot and wrought iron pot

Iron pots are mostly made of pig iron and generally do not contain other chemicals.

Iron pots are the safest kitchenware at present.

In the process of cooking and cooking, the iron pot will not have dissolution and fall off.

Even if iron is dissolved, it is good for the human body to absorb.

In terms of materials, iron pots are mainly divided into refined iron pots and cast iron pots.

Cast iron pot is what we often call pig iron pot.

In addition, according to the nature of the lid, iron pans can be divided into uncovered, glass covered and stainless steel covered iron pans.

Advantages of pig iron pot:

The heat transfer is uniform. When the fire temperature exceeds 200 ℃, the pig iron pot will control the temperature transmitted to the food at 230 ℃ by emitting certain heat energy.


Slow heat transfer, thick pot ring, rough grain and easy to crack

Advantages of refined iron pot:

It is made of refined iron, with less impurities, thin pot ring, high temperature in the pot, fast heat transfer, easy cleaning and exquisite appearance.


Pass the temperature of the fire directly to the food.

pig iron or wrought iron

From the details of life, which is better, pig iron pot or wrought iron pot?

1. Consider from the perspective of saving dyes and electricity, such as diesel and gas.

The wrought iron has good ductility and high toughness. It can forge the pot relatively thin.

The wrought iron pot has fast heat transfer, while the pig iron pot is relatively brittle.

There is no way to produce the pig iron pot by casting.

The pig iron pot has no faster heat transfer than the wrought iron pot.

Therefore, the wrought iron pot is better than the pig iron pot.

2. From the perspective of daily cleaning

Raw iron pot is a little easier than wrought iron pot. In the case of frequent use, the pig iron pot is not easy to rust as long as the detergent is not abused, the oil film on the surface is thoroughly washed, and it is cleaned in time after cooking.

However, the wrought iron pot needs to be washed and dried after use, or coated with oil film, otherwise, it is easy to rust.

3. An iron pan used for frying food

The heat transfer of pig iron pan is generally slower than that of wrought iron pan, and the heat dissipation rate is higher than that of wrought iron pan.

Because when frying food, the pig iron pot is more difficult to paste than the wrought iron pot, and the oil temperature is not easy to be too high.

Too high oil temperature will lead to food coking, so it will be better to choose the pig iron pot.

4. Consideration on rust prevention of iron pot

The surface of the pig iron pot has low smoothness and fine cracks.

If you fry food for a long time, a layer of carbide film and oil film will be formed on the surface, which can prevent the oil temperature from being too high on the one hand and rust on the other hand.

The surface of the wrought iron pot is smooth. Unless the food is fried, it is difficult to form pot scale.

5. Big cooking, big boiling and other non family daily cooking

It’s better to choose a pig iron pot.

On the one hand, the price of large pots is relatively high.

Raw iron pots are much cheaper than wrought iron pots.

Cooked iron pots cannot be made too thin, otherwise, they will be soft and deformed, so the price is relatively high.

On the other hand, the pot is often exposed to a large number of substances such as salt, soy sauce and vinegar, which is easy to corrode the pot wall.

In this case, the wrought iron pot is easier to rust than the pig iron pot.

Tips for choosing and using iron pot

1. Check whether the pot surface is smooth

Check whether the pot surface is smooth, but it cannot be as smooth as a mirror.

Due to the casting process, the iron pots have irregular shallow lines.

Iron with defects and small bulges generally has little impact on the quality of the pot, but small pits do great harm to the quality of the pot, so you should pay attention to it when buying.

2. Check the thickness and uniformity of the pot

The pot with uneven thickness is not good.

When buying, you can turn the bottom of the pot upside down, hold the concave center of the pot with your fingers and knock it with a hard object.

The louder the sound of the pot, the greater the hand vibration, and the better the pot.

In addition, the pot with rust spots is not necessarily of poor quality.

The pot with rust spots indicates a long storage time, so the internal organization of the pot can become more stable and is not easy to crack when used for the first time.

3. Identify the brand and manufacturer’s reputation

The use of iron pots produced by brand manufacturers is guaranteed.

Friends who have been home for a long time have experience in the purchase of pots and tools.

If they buy iron pots in physical stores, they can choose suitable iron pots according to their purchase skills.

However, for friends who prefer online shopping, it is very necessary to choose reputable brand iron pots because they can’t verify the advantages and disadvantages of iron pots on the spot.

Which is better, pig iron pot or iron pot?

In fact, it still depends on the demand.

There is no perfect pot.

Only the pot that perfectly fits the demand can be selected according to the demand.
