Ceramic dinnerware refers to all artificial industrial products with inorganic non-metallic minerals as raw materials, such as clay. It includes various products made of clay or mixtures containing clay, by mixing, forming and calcining. Due to the different production techniques, The type of ceramic dinner ranges from rough potter to refine porcelain.
The fabrication and application of ceramic dinnerware has a long history. Its diverse shapes, colorida, cool and smooth feel, easy to wash, are deeply loved by people all over the world.
The production methods of ceramic dinnerware are divided into on-glaze color, under-glaze color and in-glaze color. On-glaze ceramics are pasted on the glaze by stickers made of pigment or painted directly on the surface of the product with pigment, and then baked at low temperature. Because the baking temperature cannot melt the glaze, the flower coating cannot be incorporated into the glaze.Touching the on-glaze ceramics with your hand, and feeling that the flower coating has the uneven impression.
O baking temperature (higher temperature) of the in-glaze color ceramics can make the glaze melt, and the pigment can be incorporated into the glaze. After cooling, the pigment is covered by the glaze layer. The surface of the product is smooth, and there is no obvious concave convex feeling by hand touching.
The under-glaze colored ceramics are decorated on the porcelain body. Depois de envidraçado, they are fired at a high temperature. The flower coating is covered by the glaze layer. Portanto, the ceramics look bright, flat and smooth.
Because of the diversity of ceramic technology, many different types of ceramic dinnerware have been produced.

Porcelana
Porcelain is a kind of super high temperature ceramics. Therefore, it is strength, translúcido, branco. No entanto, with the development of modern technology, you can hardly see any difference between pottery and porcelain. They are all made with similar technology.
The main difference is color. Classic ceramic dinner are hard, strong, durable and heat-resistant, and have no function on other chemicals. No entanto, they are fragile under different Condition.
Grés
Stoneware is a kind of super durable ceramics. It is a solid, hard, non porous ceramic, made at high temperature until vitrified. It can be made into various clay colors.
No entanto, it is more opaque than other types of ceramics， such as porcelain. You can use stone dinnerware to store, cook, bake and serve. Em outras palavras, it has complete functions and affordable prices and it can meet the dietary needs of most people.
Faiança
Unlike general ceramics, earthenware is made at a lower temperature. Por isso, its strength is not as good as other types of ceramics. It is fragile and a little porous. The earthenware is usually burned once, then glazed, and sometimes burned again. Earthenware dinner are heavy, thick, so easy to chip, and it doesn’t need a lot of budget, which can reduce the burden on families in some extent.
Among the three types of ceramics, porcelain is more popular because of its exquisite and durable nature. It is also made more widely in the field of ceramic dinnerware making, and ranks first in the field of ceramics. Now, Let’s explore the difference between porcelain plates and general ceramic plates in more detail.

Porcelain is only one kind of ceramics. No entanto, unlike general ceramics, the clay that is used to make porcelain is very fine. It also hardens at high temperatures. This is why porcelain plates are stronger, less porous and more durable than general ceramic plates. Porcelain plates also have higher density and higher mechanical (crack and chip) resistance.
People also buy Porcelain because it is more attractive and more suitable for some special occasions and activities. This kind of plates is made of kaolin clay, normal clay, quartz sand and feldspar. Nevertheless, it can also contain other materials, such as bone ash, granite, vidro, talc, spherical clay, alabaster, etc.
The main feature of porcelain plates is translucidez. They are usually translucent white, em outras palavras, you can see light passing through them. Other general ceramic plates do not have this feature and they are more opaque. Porcelain plates can also be used as a layer on cast iron tools, because it can provide chemical free and non stick coatings for things, such as stews and ovens.
Dinnerware made of porcelain are more popular than general ones. In order to determine which dinnerware is more suitable for your cooking needs, let’s summarize five main differences between them. these can help you make better decisions.
The differences between the two are mainly reflected in:
1. Dureza
Porcelain plates are more durable and stronger than general ceramic plates because they are heated at higher temperatures. Compared with porcelain plates, the hardness of general ceramic plates can only be used at room temperature.
2. Raw Materials
Porcelain plates and general ceramic plates are made of clay heated at different temperatures. The difference is that porcelain plates are generally made of special clay, such as kaolin clay; general ceramic plates are made of ordinary clay and other materials.
3. Manufacturing Process
Porcelain plates are made at high temperature, which exceeds 2300 ° F, sometimes even 2600 ° F. Portanto, they are very hard. While the general ceramic plates are made at a lower temperature (1200 ° F or lower), they are a little porous, so they are usually burned once, then glazed, and then burned a second time. General ceramic plates are thick and heavy, and they break easily.
4. Color Style
General ceramic plates are more opaque and thicker than porcelain plates with simple appearance. Unlike porcelain plates, they are more exquisite, thinner, translucent and attractive.
5. Preço
General ceramic plates are not as expensive as porcelain plates. If you are looking for a cheaper option, there is no doubt that general ceramic plates are cheaper. Portanto, people usually prefer general ceramic plates for daily and life settings. Por outro lado, porcelain plates are the first choice for some formal meals and special occasions.

How to Make Porcelain?
Porcelain is made in several steps. The first is the crushing of raw materials. Usually, porcelain is made of feldspar, clay and silica. These raw materials are measured accurately and then crushed in different units. During this step of the production process, each large pieces will be removed. Então, the final product is mixed with water. Once these mixtures are wetted and cleaned, different molding techniques (including soft plastic molding and hard plastic molding) can be used to generate porcelain embryos. Like traditional ceramics, the next heating is carried out under the high temperature of the kiln (industrial oven).
Just like ceramics, there are different types of porcelain, including bone china, soft porcelain and hard porcelain.
1. Bone China
Bone china is one of the most durable porcelain. It has high whiteness and translucency. Bone china dinnerware is made of kaolin clay, feldspar and bone ash.
2. Soft-Paste
Soft-Paste also known as “artificial porcelain”, this kind of porcelain is more fragile because production does not require ultra-high temperature or some other special minerals. Portanto, it is easier to crack when it is filled with hot water. This is one of the most fragile porcelain dinnerware, but it is also the most affordable.
3. Hard-Paste
Unlike “artificial porcelain”, hard-paste porcelain is also called “real porcelain”. It is made of kaolin clay, feldspar and talc. It also hardens at very high temperatures.

Bone china is considered to be the strongest porcelain material. Plates made of bone china have a longer service life and are more resistant to occasional damage. The hardness of general porcelain plates are slightly inferior to bone china plates.
2. Raw Materials
Bone china plates are made of porcelain clay, porcelain stone and bone ash (made of some animals’ bones). General porcelain plates do not contain any ashes, and are usually made of general clay, frosted glass, feldspar and other materials. It is worth mentioning that Chinese porcelain is mostly made of pegmatite granite and kaolin.
3. Manufacturing Process
Bone china plates are the combination of argila de porcelana, pedra de porcelana, bone ash or a combination of the three with porcelain clay, and is fired at a temperature slightly lower than that of general porcelain plates. Geralmente, the maximum firing temperature of bone china plates is 2228 degrees Fahrenheit (1220 graus Celsius). General porcelain plates are fired at a higher temperature in a kiln. Usually, general porcelain plates are fired at a temperature of about 2650 degrees Fahrenheit (1454 graus Celsius).
4. Color Style
Bone china plates are famous for its unique, creamy soft color when bone ashes are added to the mixture. Bone china plates are translucent, permitindo que mais luz entre, while general porcelain plates will block most of the light. Therefor, Bone china plates are more grayish white than general porcelain plates.
5.Preço
De um modo geral, Bone China that meets the general standard is more expensive than general porcelain plates of the same standard. Por isso, Bone china is mostly used for collection and exhibition in daily life. The price of general porcelain plates will be more in line with public expectations.
