and step three, naturally cooling the ceramic blank after the second biscuit firing, then carrying out glaze firing molding after the ceramic blank is subjected to glaze dipping treatment, and naturally cooling the ceramic after the glaze firing is finished.
Preferably, the temperature of the first biscuit firing is 700-960 ℃, and the time of the first biscuit firing is 6-8 hours.
Preferably, the second biscuit firing temperature is 1100-1200 ℃, and the second biscuit firing time is 3-5 hours.
Preferably, the glaze firing temperature is 800-.
Preferably, the transition layer slurry comprises, by weight: 30-35% of purple sand mud powder, 5-10% of rice husk powder and the balance of water.
Preferably, the purple sand mud powder is purple sand mud dry powder, and the preparation method of the purple sand mud dry powder comprises the following steps: taking the purple sand mud for drying, grinding the purple sand dry mud after drying, and screening by a 200-mesh and 300-mesh sieve to obtain the purple sand mud dry powder.
Preferably, the rice husk powder is a cereal husk powder, and the preparation method of the cereal husk powder comprises the following steps: soaking and cleaning the grain hulls with clear water of 40-50 times of the weight of the grain hulls for 2-4 times, wherein the soaking time is 30-60 minutes each time, taking out the soaked grain hulls, draining the water, drying the soaked grain hulls to obtain dry grain hulls, grinding the dry grain hulls, and screening the dry grain hulls by a 300-mesh screen to obtain the grain hull powder.
Preferably, the preparation method of the transition layer slurry comprises the following steps: uniformly stirring the purple sand mud powder and the rice husk powder, adding water, and continuously stirring until the mixture is pasty.
The invention has the following beneficial effects:
according to the invention, the transition layer is added between the ceramic body and the glaze layer, and the control degree of the thickness of the glaze layer is improved through the penetration of the glaze layer to the transition layer; the red porcelain earth of a large amount of gas pockets can be formed through using the body shaping back to the transition layer slurry to through adding the chaff powder in the transition layer slurry, after through the bisque fever for the second time, the chaff powder leaves more spaces behind the burning under the high temperature, and during glaze is soaked again afterwards, the glaze can form half glaze and half a pottery structure in the infiltration transition layer more easily, can hug closely the glaze layer at the body surface.
Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention relates to a glaze dipping process for ceramic glazing, which comprises the following steps:
firstly, clay is used for manufacturing a ceramic body, and the manufactured ceramic body is subjected to primary biscuit firing;
naturally cooling the ceramic blank after the first biscuit firing, then coating the transition layer slurry on the part, needing glazing, of the ceramic blank after the first biscuit firing, and carrying out the second biscuit firing on the ceramic blank coated with the transition layer slurry;
and step three, naturally cooling the ceramic blank after the second biscuit firing, then carrying out glaze firing molding after the ceramic blank is subjected to glaze dipping treatment, and naturally cooling the ceramic after the glaze firing is finished.
Wherein the temperature of the first biscuit firing is 700-.
Wherein the second biscuit firing temperature is 1100-1200 ℃, and the second biscuit firing time is 3-5 hours.
Wherein the glaze firing temperature is 800-1050 ℃.
Wherein, the slurry of the transition layer comprises the following components in percentage by weight: 30-35% of purple sand mud powder, 5-10% of rice husk powder and the balance of water.
The preparation method of the purple sand mud powder comprises the following steps: taking the purple sand mud for drying, grinding the purple sand dry mud after drying, and screening by a 200-mesh and 300-mesh sieve to obtain the purple sand mud dry powder.
