How to distinguish a casserole from good or bad, how to choose a casserole

1. Look at the color: Most of the high-quality casserole colors are white, because the white pottery is rich in iron oxide, and the artificially added pigment content is relatively small, and there are relatively few impurities. Such a casserole will not produce harmful ingredients after heating, and is more suitable for cooking food.

2. Look at the shape: the structure of the high-quality casserole is reasonable, the pot body is very symmetrical, and it is very stable on the plane and will not shake. Then look at the lid of the pot, and the user can turn it a few more times.

If the lid is smooth and fits tightly with the mouth of the pot when turning, it means that there is no problem with the structure of this casserole.

3. Listen to the sound: the correct way is to hold up the casserole with your hand, and the user taps the side of the casserole with the lid, if the echo heard is loud and crisp, it means that the casserole has a high density, a good degree of firing, and no and is not easy to crack. If the echo is dull after tapping, it means that the density of the casserole is low, the degree of firing is not good, or there are cracks, and users must pay more attention when using it.

The sound of the casserole is related to the density and sintering of the casserole.

Good degree of sintering – high density – crisp sound.

The degree of sintering is not good - the density is low - the sound is dull.

If there is a crack in the casserole, the sound of knocking will also be hoarse.

So when choosing a casserole, knock the casserole with your hands, if the sound is crisp, it means that the quality is better.

Knock, listen, if the echo is long, and the sound is crisp, it is fine, if there is a crack, and the sound sounds dull, there is a problem.

Gently tap the casserole with your hands, and if the sound is crisp, it's good! If the voice is hoarse, it's bad! This is judged by their different timbres!

Tap the casserole to distinguish by timbre or tone (some teaching aids are timbres, and some are 2 tones).

The bad pitch is low and the good pitch is high

The timbre is hard to say according to the actual situation

Generally, casseroles will leak. Try the water when you buy it, it's good if it doesn't leak. After buying it, I have to boil the rice soup...Ho, it seems that the text is not on topic.

1.Look at the color. Good casseroles are mostly white in color. Because the white clay has few impurities, it does not decompose harmful components when heated, making it ideal for cooking.

2.Look at the ceramic. A good casserole pot has a bright and uniform surface, no protruding sand grains, no small holes, and is relatively smooth to the touch.

3.Look at the form. A good casserole pot is very symmetrical, it is stable when placed on a flat surface, and it will not shake. When turning, the lid of the pot is very smooth and tightly attached to the mouth of the pot, indicating that the structure of the casserole is reasonable.

4.Listen to the sound. Hold the casserole with your hand and tap the side of the pot with the lid.

If the echo sound is bright and crisp, it means that the density of the casserole is high, the degree of sintering is good, and there are no cracks. If the echo is dull and dull, it means that the casserole has low density, the degree of sintering is not good, and it may be that the casserole has cracks.

It should be as delicate as possible.

Tips for choosing a casserole:

1.Look at the clay quality: the clay used in a good casserole is very fine and the color is mostly white, and the quality of the surface glaze is also very high, with uniform brightness and good thermal conductivity.

2.Look at the structure: a good casserole has a reasonable structure, is placed flat, the pot body is round, the inner wall is smooth, there are no prominent sand grains, the casserole is round and uniform as a whole, complete and without cracks, and the lid is tight and not deformed.

3.Water leakage detection: When purchasing, fill the casserole with a sufficient amount of water and check whether there is any leakage. You can also use your hands to gently tap the pot body, and the sound is clear, bright and crispy.

The effect of using pots of different materials is also different, and for people who pay special attention to health in their daily diet, they like to use casseroles to stew food, so as to retain the original taste of food to the greatest extent.

When choosing a casserole, it is necessary to see if there are traces of grinding sand grains, because the raised small sand particles on the casserole can be directly polished with a grinding wheel, and many pits will be left after grinding.

Generally speaking, when choosing a casserole, we all choose a casserole with a smaller bottom, because the heat transfer performance of this casserole is relatively good, which can shorten the cooking time to a certain extent.

In addition, when choosing a casserole, you can also look at the overall thickness of the casserole, because different casseroles themselves are thick and thin.

Look at the smooth clay, indicating that the particles are fine, stir evenly, and it is not easy to crack when cooking in the later stage. If the surface is uneven, it means that the early firing and stirring are uneven, so that it is easy to crack when cooking in the later stage.

Listen to the sound You can use the lid to tap the body of the pot, if the sound is crisp and loud, it means that the density is high and the firing degree is good, if the sound is dull, it means that the casserole has low density, the firing degree is not good, and even has cracked.

Look at the shape Rotate the lid a few times to see if it fits the edge of the pot, and at the same time put it on a flat surface to see if it is stable and not easy to shake.
