Why does the red azalea casserole glaze unevenly

First of all, the concept of pottery has no necessary relationship with the glaze. Yixing purple sand pot is not glazed in most cases, but this belongs to the problem of the material process characteristics of the purple sand itself, because the particles of the purple sand mud are delicate, and there is a very good looking mica luster, the texture is very moist, and the firing temperature of the purple sand is relatively low, and it is more beautiful if not glazed, which has created the unique art of purple sand today. The purple sand ware of the Ming and Qing dynasties was also glazed, but the effect was far less beautiful than that of the plain tire, and later generations did not study it.

Regarding the difference between pottery and porcelain, from the perspective of silicate chemistry, it can be said that ceramics have no absolute boundaries, they are all silicon-aluminum compounds.

The higher the purity, the more porcelain has the characteristics of porcelain, and the so-called pottery is because silicates contain various impurities, such as: iron, manganese, titanium, and other metal compounds and sulfides, etc. Reducing the whiteness and temperature of the mud, as well as the physical strength, density, and so on, is called pottery.

There are various states of ceramic clay in nature, containing impurities, as well as different chemical compositions, there are a variety of physical and chemical properties, and they are also divided into various names, and what is more interesting is that due to the different content of impurities, in fact, it is impossible to absolutely divide who is pottery and who is porcelain!

The so-called distinction between ceramics is, in most cases, a customary title under the premise of humanistic inheritance.

Most of the casseroles are made by hand, it is inevitable that there will be uneven glaze, in fact, it does not affect the use, buy a casserole is more concerned about health and durability, my home is the red azalea casserole, very good! It's delicious to make bone broth!

Unglazed.

The enamel of the casserole contains a small amount of lead, which is easy to dissolve when cooking acidic food, which is harmful to health, so it is best to choose a casserole with a natural color on the inner wall. If the inner wall of the casserole is colored, it is not suitable to store wine, vinegar, acidic drinks and food. The newly bought casserole can be soaked and boiled in 4% vinegar water to remove most of the harmful substances.

Tips for buying 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 flatly, the pot body is round, the inner wall is smooth, there are no cracks and cracks, and there are no protruding sand particles. The lid is tight and does not change its shape, you can try to turn the lid on the lid to see, if the lid is tightly attached to the body of the pot, it should be smooth friction when turning.

In fact, if it is not glazed, the dishes are the same. However, the casserole with internal glazing is more convenient to clean after use, and the glazed casserole is stronger, so it is recommended that you buy a glazed one.

It is best to glaze the inside, which is more convenient to use and clean.

Otherwise, the food that makes the fishy smell, garlic, and even the stored food is spoiled, and the weird taste will remain for a long time.

The top one is better, but if there is a little glaze, if you put it on the stove and burn it, the bottom is easy to turn black.

Of course it's not uranium! The taste of the finished product is much different! The glazed ones are also prone to cracking!

The underglaze, mid-glaze, and overglaze colors in porcelain can all be toxic. Ceramics are acid-resistant, alkali-resistant, and high-temperature resistant. It is best for steaming, boiling, boiling, and roasting Chinese food.

However, a national quality inspection results show that a quarter of the ceramic tableware lead, cadmium and other heavy metal content seriously exceeds the standard, which is a substandard product.

A very important reason for the toxicity of ceramic coatings is that in order to ensure the good combination of pigments and ceramic molds, some co-solvents will be added when coloring, and the co-solvents contain a certain amount of toxic substances such as lead and cadmium, especially yellow and green. When choosing bowls, plates, etc., it is best to choose yellow and green carefully. It is best to choose plain white colorless and non-printed containers, or ceramic pure white interiors.

It is made of mineral raw materials (feldspar, quartz, talc, kaolin, etc.) and chemical raw materials in a certain proportion (some raw materials can be made into frit first) after grinding to make glaze slurry, applied to the surface of the green body, and calcined at a certain temperature. It can increase the mechanical strength, thermal stability and dielectric strength of the product, as well as beautify the utensils, easy to wipe, and not be eroded by dust and filth.

It has not been found to be harmful since ancient times.

It is glaze and is harmless to the body.

Most of the bowls, plates, basins, etc. widely used in life are glazed, and the glaze is a continuous vitreous layer attached to the surface of the ceramic body, or a mixed layer of glass and crystal. The glaze may be produced by calcium-containing stones and charcoal ash used in ancient stone cooking, or it may be inspired by the beautiful texture of the surface of shells, and consciously made of shell powder as raw materials.

Casserole maintenance tips:

The casserole you just bought needs to be treated, such as boiling it with rice washing water, which can prevent the casserole from bursting in use.

When the casserole is used for the first time, you need to use a small brush to brush off a lot of small sand particles on the inner wall of the casserole to prevent the sand particles from falling into the food.

Newly bought casseroles often leak because there are many trachomas. When the new pot is used for the first time, it is best to make noodle soup or gruel, after eating, do not brush the pot first, put it on the stove and bake it, so that the batter in the pot is dry and knotted, block those tiny sand holes on the wall of the pot, and then wash it. This way, the casserole won't leak.

Do not quench when cooking, and if you need to add water, you should also add hot water to avoid cold and heat shock, reducing its service life.

Handle it gently, don't "touch hard", after all, it is a clay product, and bumping will make it "incomplete".

The proprietress is right, there are many kinds, there are glazed on the inside, and there are no glazed ones, and glazed soup is generally used. That's not something you can't cook.

I read about casseroles in a book a long time ago, and that thing is exactly what Smoke says. To give you some common sense about casserole: 1. How to use casserole 1:

When the newly bought casserole is used for the first time, it is best to use it to boil porridge, or use it to boil thick rice water to block the microscopic pores of the casserole and prevent water seepage 2: When using a casserole to boil soup and stew meat, you should first put water in the casserole, and then put the casserole on the fire, first use a simmer, and then use a strong fire.

3: When serving the casserole from the fire, be sure to place it on a dry wooden board or straw mat, never on a tile or concrete floor.

A real casserole is unglazed.

The quality is goodMy home is the old brand. Now if the things bought online are broken in transportation, they will be reissued. As for whether it will crack, on the one hand, you have to buy a *** casserole You can't be greedy for that cheapness, on the other hand, it depends on how you use it Don't burn it at the beginning.

Ceramic tableware has always been a kitchen item that many families or restaurants are very much needed, and ceramic tableware is not only beautiful but also relatively harmless to the material. As one of the old brands, red rhododendron ceramics has achieved good results in both franchise stores and factory direct sales. Red rhododendron ceramics are mainly engaged in four series of environmentally friendly high-white underglaze color bowls, plates, saucers, cups and high-end magnesia porcelain.

I bought it on November 9, 2019 and it cracked after using it for the second time. No return or exchange will be given. Don't buy red cuckoo casseroles. There are quality problems that have not been solved. There is no morality.

The red casserole is garbage, I just bought a casserole, I used it twice and halved it, and the dealer did not change it, saying that this brand casserole was not resistant to high temperatures.

Yes, there is lead in the glaze, but it is okay if it meets the food safety requirements.

The black glaze on the inside of the casserole will happen if it falls into the soup and is absorbed by the body when it is used?

Glaze is a natural substance applied to porcelain, pottery or clay pots, which is actually the smooth layer on the rice bowl. There is no essential difference with glass, but it plays the role of bright, beautiful and easy to clean. It has a history of thousands of years and has no adverse effects on the human body.

Glaze, in fact, is a glass-like coating on the outside, which is not fundamentally different from glass.

1. Effect. The casserole is a pot made of clay and sand fired with a layer of glaze, the appearance is smooth and modern, bright and hygienic, generally used to make soup dishes, the casserole has small pores, is less resistant to high temperatures, has a large pot mouth, and dissipates heat quickly. It is directly heated and matured over medium and low heat, and there are also heating methods such as steaming and stewing over water.

2. Security. It is advisable to choose a casserole with a delicate texture for soup, as the porcelain enamel of an inferior casserole contains a small amount of lead, which is easy to dissolve when cooking acidic food, which is harmful to health. The clay pot with a white inner wall is very useful.

The advantage of the casserole is that it needs to be slowed down and the heat retention is good, and the soup made is extremely delicious.

3. Material. The casserole is made of refractory clay, which is formed by semi-dry pressing and then melted. Due to the impurities contained in the fired clay or artificially incorporated with colorants, it can be in various colors such as red, green, blue, and yellow.

In the early days, unglazed ceramics only had one kind of red, commonly known as cylinder bricks, and there were two shapes: square and hexagonal.

Glaze is an ancient technique that makes the surface of pottery smooth, and the smooth place of the general pottery casserole is called glaze, which is basically the case with any pottery, and the part that feels like a brick or frosted material is not glazed. In short, the biggest difference between the two is the texture, but after all, it is tableware, and no one will care too much about it.

The quality of the casserole can be mastered in three ways: one knock, two looks, and three shakes.

1) Knock on the --- with a flick of your fingers, you can immediately know the quality of the casserole, the better the sound is the more crisp, which means that the higher the firing temperature, the better the heat preservation effect, and will not crack off with a light touch.

If the sound is muffled--- low and there is no echo, it is of bad quality.

2) Look at the gradient - you can see the pattern on the lid, the more layered, the more lifelike the feeling, which means that the higher the temperature of firing, in order to make the glaze go deep into the casserole, and then produce a sense of layering.

3) Shake --- if it is broken, you can pick it up and shake it slightly, there may be a rustling sound, if so, do not buy it.

Generally, the clay pot is made of pottery and glazed, as long as there is no dark wound and no eye of the wind, it can be used for a long time to buy a new one and observe the appearance and inner tank.

Is this kind of casserole ** sold? Why can't I find a place to buy anywhere? The kind in the supermarket doesn't work well.
