Stoneware is called "stone-bodied porcelain" in ancient Chinese books. The body is dense and has been completely sintered, which is very close to porcelain. But it has not yet been vitrified (Vitrification), and still has a water absorption rate of less than 2%. The green body is opaque, some are white, and most are allowed to show color after firing, so the requirements for the purity of the raw materials are not as high as those of porcelain. The raw materials are obtained easy. Stoneware has high strength and good thermal stability, is well adapted to modern mechanized washing, and can smoothly pass through sudden temperature changes from the refrigerator to the oven. In the international market, due to the development of tourism and the socialization of diet, Stoneware has a greater sales volume than enameled pottery.

Also known as the cylinder. Products between pottery and porcelain, such as water jars, etc.
The raw materials commonly contain more illite clay. The green body is easy to be densely sintered, the water absorption rate is generally below 6%, it is opaque, unglazed and not water-permeable. The texture is dense and hard, similar to porcelain, and is mostly brown, yellow-brown or gray-blue.
Many chemical ceramics and architectural ceramics fall into the stoneware category. Stoneware with a water absorption rate below 3% and a body close to white is called fine stoneware, also known as white stoneware. It has the characteristics of impact resistance, resistance to inorganic acids (except hydrofluoric acid) and good thermal stability. Stoneware tableware is suitable for mechanical washing.

and unglazed parts are also impermeable (water-absorbing) rate below 6%). No light transmittance. Many chemical ceramics and architectural ceramics fall into the range of stoneware. Stoneware with a water absorption rate below 3% and a body close to white is called fine stoneware. It has the characteristics of impact resistance, corrosion resistance of inorganic acids (except hydrofluoric acid) and excellent thermal stability.
Purple sand is also a type of stoneware.
Features Editor
Stoneware is a ceramic product between pottery and porcelain. It is stronger and has lower water absorption than pottery. It has better thermal stability and lower cost than porcelain. , Production raw materials come from a wide range of origins. Such as water tanks, etc., the texture is dense and hard, similar to porcelain, and is mostly brown, yellow-brown or gray-blue.
Function Editor
"Stoneware" has very good performance, so it can also be used to make sanitary ware, acid-resistant containers, etc. Stoneware generally has a straight cylindrical shape, with soft corners (the turning line is not obvious and is in the shape of an arc), giving it a simple, thick and rough style. Thick body, round and thick edges, not afraid of impact, also known as "thick body porcelain"
"Stoneware" porcelain has poor transparency. It is generally made of white glaze, and sometimes colored glaze is added. The decoration is mainly made of colored glaze and underglaze colored edges, lines or color blocks. The picture is suitable for flat-coated patterns, and the shape and decoration form a unified style. The patterns are mostly painted on the plain body and then fired with transparent glaze; some add color on the glaze, usually by spraying, or silk screen paper.
