Glaze slip for preparing transmutation glaze and preparation method of transmutation glaze
The invention discloses glaze slip for preparing a transmutation glaze surface and a preparation method of the transmutation glaze surface. The glaze slip is prepared from the following raw materials in parts by mass: 42 parts of potassium feldspar, 7 parts of Suzhou soil, 5 parts of quartz, 0-8 parts of calcite, 9 parts of zinc oxide, 6.2 parts of titanium dioxide, 25 parts of frit, 7 parts of barium carbonate, 1.4 parts of copper oxide and 2 parts of cobalt oxide. The fineness of the glaze slip reaches 250 meshes, and the specific gravity is 1.5-1.6 g/cm < 3 >. The principle that the opacifying effect of titanium is poor under the condition that the calcium content is low is utilized, and a glaze surface with a transmutation effect is generated through reaction. When the calcium content is moderate, the glaze surface glossiness is good; when the calcium content is low, the glaze surface is poor in glossiness, the glaze surface is matte or even dark, and the color changes to black brown; and the glaze surface is green when the calcium content is high. By controlling the fineness of the glaze slip, the firing quality of the glaze surface is ensured; and by controlling the spraying thickness of the glaze layer, the furnace transmutation effect of the glaze color is ensured. The thermal stability, microwave oven test and lead and cadmium dissolution amount of the product can reach the standard of daily tableware.
本发明的一种用于制备窑变釉面的釉浆及窑变釉面的制备方法，釉浆的原料按质量份包括42份钾长石、7份苏州土、5份石英、0‑8份方解石、9份氧化锌、6.2份钛白粉、25份熔块、7份碳酸钡、1.4份氧化铜、2份氧化钴；釉浆的细度达250目，比重为1.5‑1.6g/cm3。其利用钛在钙含量较少的情况下乳浊效果较差的原理，反应产生具有窑变效果的釉面。钙含量适中时釉面光泽度好；钙含量较低时釉面光泽度差，釉面为哑光甚至无光，颜色向黑褐色变化；钙含量较高时釉面为绿色。通过控制釉浆的细度，保证釉面烧成质量；通过控制釉层的喷涂厚度，保证釉面颜色的窑变效果。其热稳性、微波炉测试、铅镉溶出量均能达到日用餐具的标准。
