What is the difference between firing porcelain and making clay pots?

The porcelain is relatively fine, the real firing temperature is high, and it is generally fired in flames, that is, the porcelain body is placed in a fire-resistant sagger, and the fire is not eaten directly. Crockpots are not so demanding. Generally speaking, the clay pot is relatively rough, and the fire is also low, and some can be fired with an earthen kiln, which is a little rougher.

Because the materials of the two are different, the firing method is also different.

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. In the north, soup is mostly made, and in the south it is called a pot.

Nowadays, casseroles are popular in Japan for a variety of dishes, and the new generation of casseroles can not only be used for steaming and stir-frying, but also for baking pizza. Clay pots have the function of heat accumulation (most suitable for smoldering foods) and the characteristics of uniform heating. Fast heat transfer, good heat conduction, and the pot itself can absorb the sauce, so as long as the ingredients themselves are in the right proportions, they can have a good effect.

When the porcelain pot is heated, the temperature rises more slowly, so that the food can be evenly and fully heated, and the cooking is more shiny; Heat preservation can also be smoldering. The clay pot is completely made of clay, the texture is rough to the touch, the shape is relatively simple, commonly used in Hong Kong, Macao and Guangdong, the general clay pot can be stewed, boiled, stewed, the clay pot has large pores, high temperature resistance, plus the pot mouth is small, the heat dissipation is slow, and the boiling time is shorter. Pay attention to the application of heat, and the fire should not be too fierce to prevent the crockpot from breaking.

After cooking, the soup is less and the fragrance is strong.

1. The raw materials used for production are different.

Clay pot: A pot made from clay firing.

Porcelain pot: A pot fired from a combination of clay and clay.

Clay pot: It is a pot made entirely of clay, with a rough texture and a simple shape, which is commonly used in Hong Kong, Macao and Guangdong.

Porcelain is refined, and pottery is rough, that is, porcelain can not be done without a certain technology, and pottery knows how to do it casually, but the quality is not very good.

Clay pots are not considered the ancestors of porcelain. Clay pots belong to pottery, while porcelain is a kind of disadvantage of pottery, but there are certain differences between them.

Pottery is the earliest ceramic product of mankind, which began in the Neolithic period. The main raw material of pottery is clay, which is fired at high temperatures. Its main characteristics are that the texture is rougher, the material is looser, and the water absorption is higher. The clay pot is a typical representative of pottery.

Porcelain was developed after pottery, and the main raw materials were kaolin, quartz and feldspar. Porcelain is fired at a higher temperature than pottery, usually above 1200. Porcelain is characterized by delicate texture, good light transmittance, compact material, and low water absorption.

During the production process, porcelain usually undergoes processes such as glazing and firing to make its surface smoother and more beautiful.

In short, crockpots and porcelain are both ceramic products, but they differ in their raw materials, processes, and properties. As a kind of pottery, clay pots cannot be counted as the ancestors of porcelain, but they belong to different stages in the historical development of ceramic products.

Generally, it is made of clay (including shale, gangue and other powders) as the main raw material, and is made by mud treatment, molding, drying and roasting.

In ancient times, the main raw materials for firing pottery seemed to be clay and river sand, but in modern times, it is much the same.

Clay, can not have sand, after drying, above 700 degrees, natural tempering cooling.

Summary. Hello dear, gas kiln interpretation: a stove for firing bricks and ceramics with gas.

Expansion of knowledge: Porcelain is made of porcelain stone, tanpai pants kaolin, quartz stone, mullite, etc., and the exterior is glazed or painted. The forming of porcelain is to be fired at high temperature (about 1280 1400) in the kiln, and the glaze color on the surface of the porcelain will undergo various chemical changes due to the difference in temperature, which is a treasure of Chinese civilization.

China is the homeland of porcelain, which is an important creation of the ancient working people. Xie Zhaoqian recorded in "Five Miscellaneous Works": "Today's common saying that the kiln is called the magnetic ware, and the kiln in Cizhou is the most, so the name is extended, such as silver is called Miti, ink is called Mi Mi, and so on."

At that time, the envy of the "magnetic" kiln was caused by the largest output of the Cizhou Rangjian kiln. This is the earliest historical material found to use the title of porcelain.

Wrong. The difference between clay and porcelain clay is relatively large, clay refers to the clay containing iron and yellow-brown, gray-white, reddish-purple and other hues, with good plasticity, the mineral composition is complex, mainly composed of kaolinite, water muscovite, montmorillonite, quartz and feldspar, mainly distributed in the area of Xiaohengshan. The ore-bearing horizon is mainly silty clay in the upper Cretaceous, residual slope accumulation and alluvial slope accumulation in the Tertiary and silty clay in the Upper Pleistocene Qizui Formation in the Quaternary.

Pure china clay is a kind of white or off-white, silky luster soft mineral, which is formed by the metamorphism of mica and feldspar, in which sodium, potassium, calcium, iron, etc. are lost, and water changes, this effect is called "china soilization" or "kaolinization".

So there is a huge difference between the two.
