Secret-color porcelain glaze and preparation method thereof
The invention belongs to the technical field of glaze preparation, and particularly relates to secret-color porcelain glaze which is prepared from the following raw materials in parts by weight: 45-60parts of potassium feldspar, 12-20 parts of quartz, 7-15 parts of fluorite, 12-20 parts of plant ash, 1-3 parts of titanium oxide, 1-3 parts of ferric oxide, 1-3 parts of gold ore and 1-3 parts of marble. The invention also discloses a preparation method of the secret-color porcelain glaze. The preparation method comprises the following steps: (1) weighing the raw materials according to the proportion,(2) fully crushing the raw materials, and uniformly mixing to obtain a mixed glaze material, (3) adding the mixed glaze into a ball mill, and adding water for ball milling to obtain glaze slip,(4) uniformly applying the glaze slip to a biscuiting blank, drying the glazed blank, putting the dried glazed blank into a kiln for firing, heating to 1260-1300 DEG C in an oxidizing atmosphere in astepped heating manner, keeping the temperature for 60-80 minutes, and naturally cooling to room temperature, thereby obtaining the secret-color ceramic glaze. The secret-color porcelain prepared by the raw material ratio and the preparation method disclosed by the invention is good in coloring effect, uniform in glaze color, high in glossiness, high in hardness, free of cracks and high in yield.
本发明属于釉料制备技术领域，具体涉及一种秘色瓷釉，它是由以下重量份的原料制备而成：钾长石45‑60份、石英12‑20份、萤石7‑15份、草木灰12‑20份、氧化钛1‑3份、氧化铁1‑3份、金矿石1‑3份，云石1‑3份；本发明还公开了秘色瓷釉的制备方法，包括以下步骤：（1）按上述配比称取各原料；（2）将原料充分粉碎后混匀，得混合釉料；（3）将混合釉料加入球磨机中，加水球磨，得釉浆；（4）将釉浆均匀地施敷在素烧坯上，施釉坯经干燥后放入窑炉中烧制，在氧化气氛中，采用阶梯式升温方式将温度升高至1260~1300℃，保温60~80min，自然冷却至室温，得到秘色瓷釉；通过本发明公开的原料配比和制备方法制得的秘色瓷的着色效果好，釉色均匀，光泽度高，硬度大，无裂纹，成品率高。
