Purple ceramic firewood burning method

Abstract

The invention discloses a purple ceramic firewood burning method, and belongs to the technical field of ceramics. The method comprises the following steps: 1) placing a purple ceramic body in a kiln provided with an electric heating device and a firewood burning hall, and heating with the electric heating device at the heating temperature of 800-900 DEG C for 6-8 h; 2) adding firewood for burninginto the burning hall of the kiln after the purple ceramic body is in the vitreous state and turns red, immersing the firewood in diesel oil before burning, carrying out combined burning with the firewood and the electric heating device at the burning temperature of 1150-1200 DEG C for 48-72 h, cooling the burned purple ceramic body to 100 DEG C and below and taking out to prepare the finished product. By the method, use amount of firewood can be effectively reduced, and the environmental pollution is reduced.

[0020] The firing method of purple pottery firewood, the steps are as follows:

[0021] 1) Choose dry wood (lychee wood) as the fuel, soak it in diesel oil for later use;

[0022] 2) Place the purple pottery body in the kiln, which is equipped with an electric heating device and a fire hall for burning wood. After closing the furnace door, use the electric heating device to heat. The heating temperature is 800°C and the heating time is 8 Hour;

[0023] 3) After the body of purple pottery is vitrified and red, take out the wood soaked in diesel oil, add burning firewood to the fire hall of the kiln, and use firewood and electric heating device to mix and fire at 1150°C , The firing time is 72 hours, the fired purple pottery body is cooled to below 100°C with the ceramic kiln, and the finished product is made after taking it out.
