What is the approximate temperature for firing pottery? What is the temperature at which the ceramic

It seems to be more than 1000 degrees, thank you.

The firing temperature of pottery is generally lower than that of porcelain, and the lowest even reaches below 800 and the highest can reach about 1100. The firing temperature of porcelain is relatively high, most of them are above 1200, and some even reach about 1400.

The firing temperature of the pottery is low, the body is not completely sintered, the sound is questioned when striking, the hardness of the carcass is poor, and some can even use a steel knife to cut out grooves. The firing temperature of porcelain is high, the carcass is basically sintered, the sound is crisp when striking, and it is difficult to draw grooves on the surface of the carcass with ordinary steel knives.

Due to the different industries, the ceramic firing temperature classification category is not the same

The ceramic industry is generally divided into architectural ceramics and daily ceramics, craft ceramics and special ceramics, and their respective high, medium and low firing temperatures are classified as:

The general division of architectural ceramics: low-temperature ceramics (below 700), medium-temperature ceramics (700--1200), high-temperature ceramics (above 1200);

The general division methods of daily ceramics and craft ceramics are: low-temperature ceramics (below 1200), medium-temperature ceramics (about 1250), and high-temperature ceramics (above 1300); ‘

Special ceramics are more difficult to say, there are very low firing temperatures, and there are also special ceramics suitable for high-tech applications with a firing temperature of more than 1800 degrees.

Then there is the process of ceramic firing is divided into overglaze and underglaze firing process, and the firing temperature is also different, and naturally the firing temperature is different. Glaze porcelain is a porcelain handicraft built on the porcelain that has been made into porcelain, in which the appliqué porcelain is divided into high-temperature ceramics (about 1300), medium-temperature ceramics (about 1200), and low-temperature ceramics (700-800) firing.

The classification of overglaze hand-painted porcelain is relatively simple, generally 700-800 firing; Very little high-temperature resistant overglaze hand-painted porcelain.

The ceramic industry is generally divided into several categories of architectural ceramics and daily ceramics, craft ceramics and special ceramics, and their respective high, medium and low firing temperatures are classified as: 1300: high-temperature glaze, ancient imperial kiln, underglaze color, glaze red and other colors, are high-temperature glaze.

Jingdezhen unique firing high-temperature ceramics, firing temperature of more than 1300 degrees. 1200: medium temperature glaze, 1000 common techniques of ancient folk kilns

Low-temperature glaze, daily tableware is often fired at low temperature, which is inexpensive and easy to mass-produce. 950: Glaze color, often used in the glaze blue and white gold inlay secondary sintering special technique.

900: Embossed gold, in 1300 high temperature glaze, with a thousand feet of gold water applied to the embossed gold technique, the international standard content of 12%-18%, not easy to oxidize, as good as new. Below 800:

It is called pigment, and the surface of the vessel is like porcelain and non-porcelain, and the glaze is not glazed, which is called pigment. 500: glass gold firing temperature, mixed with glass accessories firing, gold layer content of about 5%-9%, easy to oxidize, not wear-resistant.

400 -600: baked imitation glaze, contemporary often with pigment spraying, printing treatment, commonly known as baked glass coating, applied to transparent white glaze, imitation red and yellow porcelain and gold edge can be real. High-temperature ceramics in the daily field:

In the daily use and craft collection porcelain, high-temperature porcelain refers to the glaze with a firing temperature of more than 1300, and the traditional porcelain such as underglaze blue and white and glaze red in ancient China are all made at high temperature. Ceramic enamel is a triangular conical chemical bond structure stabilized by silica, and only above 1250 can there be changes at the molecular level, so that the colorant is stably placed within the molecular structure. Therefore, high-temperature porcelain has irreplaceable unique effects in terms of color, color, and material density.

The melting point of ceramics is mostly above 2000, and the highest high-steel ceramics are 3000 degrees Celsius.

The firing principle of pottery is as follows:

Ceramics are made of clay as the main raw material, and the plasticity is used to make the clay plastic into a green ceramic object, which is calcined at high temperature to make the green body undergo a series of physical and chemical reactions.

Fired into ceramics. In order to make ceramics more beautiful and functional, some of these products must be glazed and color-fired.

After mixing clay with an appropriate amount of water, it forms a mud ball, which is molded into a shape under the action of external force, and retains its shape after the external force is removed. This property is the plasticity of clay. The billet has a high yield value after forming and the bonding strength that can maintain the bond between the billet particles without falling apart after drying.

During the drying process, the water evaporates, the inter-particle voids are reduced, and the volume shrinks occurs. The addition of barren raw materials (quartz or calcined clinker) and the reduction of water volume to the blank can change excessive flowability, adjust plasticity, and reduce drying shrinkage.

Flux raw materials such as feldspar and talc in clay during high-temperature calcination.

When it reaches a certain temperature, it melts, and a liquid phase appears, which fills in the void between the unmelted particles, relying on its wettability and surface tension.

The porosity decreases, the firing volume shrinks, and at the same time, the refractory components can be dissolved, and a new crystalline phase (mullite) is precipitated from the liquid phase.

and grow. The quartz added to the raw material can be partially dissolved in the liquid phase to increase the viscosity and prevent deformation at high temperatures. The reaction of the dissolution of refractory particles and the precipitation of mullite continues, and finally, mullite, residual quartz and other crystalline phase components are linked with the glass phase (liquid phase) to form a complex structure along with the pores, forming a dense ceramic body.

According to the different compositions of ceramics, the firing temperature is different, and the melting temperature will be higher, which is also different. The melting point of ceramics is mostly above 2000, and the highest high-steel ceramics are 3000 degrees Celsius.

Summary. Hello! Glad for your question.

In general, the temperature of firing pottery can vary between 1000-1300, and the firing time will be shortened by 1-2 hours for every 10 increases. But this depends on the complexity of the pottery being fired, as well as their thickness. If the pottery is thicker, the firing time may be shortened even more for every 10 lifts.

When firing pottery, it is also necessary to pay attention to the stability of temperature, and in general, the temperature change should be within 2-3. At the end of this time, thank you for your question, I hope it can help you, and I wish you a happy life!

Hello! Glad for your question. Under normal circumstances, the temperature of firing Lupei good pottery can vary between 1000-1300, and the firing time will be shortened by 1-2 hours for every 10 times of lead is raised.

But this depends on the complexity of the pottery being fired, as well as their thickness. If the pottery is thicker, the firing time may be shortened even more for every 10 lifts. When firing pottery, it is also necessary to pay attention to the stability of temperature, and in general, the temperature change should be within 2-3.

Can you add, I don't quite understand it.

Hello, I am happy to serve you and give you the following answer: for every 10 degrees increase in the temperature of the pottery, the time will be shortened a little. In order to shorten the firing time, it is necessary to ensure that the temperature shield of the firing furnace is at its highest level, so that the firing time can be shortened.

Workaround:1First of all, it is necessary to ensure that the temperature of the furnace is at its maximum, so that the firing time can be shortened.

A certain amount of fuel can be placed in the furnace and the quality of the fuel must be the highest so that the temperature of the furnace can be reached at the highest level. 2.Secondly, it is necessary to make sure that the air circulation of the furnace is good so that the temperature of the furnace can reach the maximum.

A fan can be set on the outside of the furnace to allow good air circulation in the furnace so that the temperature of the furnace can reach the maximum. 3.Finally, make sure that the heat in the furnace is evenly distributed so that the temperature of the furnace can reach its maximum.

A certain amount of sintered material can be placed in the furnace so that the heat of the furnace can be evenly distributed, so that the temperature of the furnace can reach the maximum. Personal tip: Every 10 degrees increase in the temperature of the pottery, the time will be shortened, so if you want to shorten the firing time, you must make sure that the temperature of the firing furnace is at its highest, the air circulation is good, and the heat is evenly distributed.

Only in this way can the firing time be shortened and the firing efficiency can be improved.

Summary. If a 2 cm plank is placed at the bottom of the furnace, the temperature under the board may be slightly lower than the bottom temperature, but it may still be higher. Since the heat generated by the electric pottery stove is mainly concentrated at the bottom, the temperature below the plank may decrease somewhat after passing through a 2 cm plank, but it may still be higher than the room temperature.

Therefore, it is recommended that when the electric ceramic furnace is used, do not place flammable items or items sensitive to high temperature directly at the bottom of the electric ceramic furnace to avoid causing fire or damaging the items.

Hello, dear, high.

Need to watch out for hot hands.

The bottom temperature of the electric ceramic stove is usually higher. Since the electric ceramic furnace generates heat through the resistance wire, the heat is mainly concentrated at the bottom, and the temperature at the bottom is relatively high compared to the rest of the furnace. Therefore, when using an electric ceramic stove, it is necessary to pay attention to the bottom temperature and avoid direct contact with the oak or placing flammable materials.

Put a 2 cm wooden board under the electric ceramic stove, and the temperature under the wooden board can be said to be very low, right?

Yes, dear, it will be lower.

If a 2 cm plank is placed at the bottom of the furnace, the temperature under the board may be slightly lower than the bottom temperature, but it may still be higher. Since the heat generated by the kiln is mainly concentrated at the bottom, after passing through a 2 cm plank, the temperature under the board may be lower, but it may still be higher than the room temperature. Therefore, it is recommended that when the electric ceramic furnace is used, do not place flammable items or items sensitive to high temperature directly at the bottom of the electric ceramic furnace to avoid causing fire or damaging the items.

Kiss, I feel that the plank is not very safe, and I am afraid of it.

The temperature at this time does not ignite flammable materials?

Refers to the underside of the plank.

Dear, no.

Melamine boards should be flame retardant, right?

Yes, flame retardant.

End of question, thank you for your reply.

There are no no evaluation items in the lower left corner. Good.
