Antique ceramic and preparation method thereof
The invention relates to an antique ceramic. The blank is prepared from the following raw materials: 35-45 wt% of kaolin, 4-6 wt% of peat soil, 6-14 wt% of alkaline earth, 5-7 wt% of quartz, 25-33 wt% of bentonite, 1-3 wt% of diopside, 12-16 wt% of picrolite and 4-6 wt% of fired talcum. The preparation method of the antique ceramic is characterized by comprising the following steps: (1) weighing materials according to the formula, milling the material, balls and water in a ball mill in a mass ratio of 1:2:0.8, passing through a 200-mesh screen, and aging for 2 days; (2) injecting the blank slurry into a mold, demolding after 20 minutes, taking out the blank, drying, repairing and applying water; and (3) firing in a kiln at 900-1000 DEG C in an oxidizing atmosphere for 2-3 hours, converting into a reducing atmosphere, heating to 1150-1230 DEG C, keeping the temperature for 1-2 hours, and finally, naturally cooling to obtain the antique ceramic. The method can directly perform firing without glazing, and thus, is simple in preparation technique. The prepared antique ceramic has the advantages of low cost, natural color, abrasive surface and antique beauty.
