The difference between pottery and porcelain

The difference between pottery and porcelain: porcelain is shiny/pottery is dull, porcelain hardly absorbs water/pottery absorbs water, porcelain sounds crisp/pottery sounds dull, porcelain is transparent/pottery is opaque. The lower the firing temperature of pottery/the higher the firing temperature of porcelain. Pottery is made of clay/porcelain is made of porcelain clay. Then I will analyze it from these six aspects!

First, the appearance of glaze: the firing process of porcelain is generally high temperature, the glaze is high calcium lime glaze, the glaze is bright and shiny, the pottery is fired at low temperature, and lead is added as a solvent to fire at low temperature. Compared with porcelain, pottery is rough, and lead on the surface of pottery is harmful to our health, so pottery is often used as a funerary object.

Second, water absorption: porcelain hardly absorbs water, and the water absorption rate is generally less than 0.2%. Pottery generally has water absorption, and the water absorption rate is generally greater than 10%.

Third, the sound: when we knock on porcelain, we usually make a crisp sound, which is very pleasant. But when you knock on pottery, you will make a dull sound and have a dull feeling.

Fourth, color: porcelain has translucent, gray, black and white colors, and the fracture is similar to glass; Moreover, pottery is opaque, with red, gray, white and other colors, and the fracture is rough.

5. Temperature: The firing temperature of pottery is generally between 700 and 800 degrees, porcelain is generally at 1200 degrees, and modern porcelain is above 1 100 degrees.

Raw materials: Pottery is made of ordinary clay, and porcelain is made of porcelain clay. Kaolin is generally used as the main material. Kaolin is a kind of soft soil with good plasticity and fire resistance. Now it is also used to make pottery.

In fact, all the bowls we eat at home now belong to porcelain. The bowl used for eating in my house is no exception. They are also porcelain, with smooth glaze and beautiful appearance and patterns. There used to be ten porcelain bowls at home, but now there are only eight. One of them was injured for a long time because his son accidentally fell to the ground while eating. The other one was borrowed by a neighbor and not returned. I'm embarrassed to ask for it. In addition to this porcelain bowl for eating, there are also pottery bowls at home.

Little friends, do you know the difference between ceramics? If you don't understand anything, you can write your questions in the comments section below, and I will definitely reply to you! Look forward to your participation.
