No-cracking Ru porcelain tableware and no-cracking manufacture method of Ru porcelain tableware

Abstract

The invention discloses no-cracking Ru porcelain tableware and a no-cracking manufacture method of the Ru porcelain tableware. The porcelain comprises: a blank body and glaze materials which are usedfor manufacturing tableware; the blank body raw materials comprise Tanggou soil, Banpo soil and Heimao soil; the glaze raw materials comprise mica, horseshoe stones, agate stones, plant ash and sheepbone meal; the blank body raw materials and the glaze raw materials are crushed, water is added, wet grinding is carried out, and water is discharged after precipitation; slurry of the blank body rawmaterial is injected into a mold, and firing is carried out for forming a biscuit; glazing is carried out on the outer surface of the blank body raw material biscuit; and the blank body is placed intoa kiln, the furnace temperature of the kiln is raised to 1050 DEG C, heating is carried out at a speed of 1 DEG C every two minutes, when temperature is increased to 1280-1300 DEG C, heat preservation and firing are carried out on the blank body under a condition of 1280-1300 DEG C, and then firing is finished. Through the mode, according to the porcelain provided by the invention, the formula ofthe porcelain and the manufacturing method are improved, the expansion coefficients of the glaze materials and the biscuit are consistent, so that the phenomenon that existing Ru porcelain is crackedand the glaze surface of the surface is cracked is changed, no cracks and no fracture exist on the porcelain, and the manufactured porcelain can be made into high-grade tableware.
