宜兴均陶釉料的制备与工艺

Glaze Production and Feature of Yixing Jun Pottery

宜兴均陶使用釉料的制作工艺与特点,它是从原先粗陶的基础上通过釉料配方变化,经窑变而形成的一个独特釉种,均陶釉大多就地取材,由土釉发展而来,其烧成温度一般在1230 ℃左右。均釉种类比较丰富,有高光和亚光釉、单层和复层釉等多种类釉色,本文列举了多种经典均釉的配方特色,传统均釉属于有光系列,其乳浊部分与基体部分都有良好的光泽反射,乳浊体夹杂于基体色釉中,两者交融部分产生有光窑变色晕。现代均陶釉发展方向则为亚光系列,灰橙黄绿青蓝紫各色在浑厚的釉中相互熔融流动。

The glaze of Yixing Jun Pottery made on the basis of original raw pottery with changes to the original glaze formula is a kind of special glazes through kiln transmutation. The glaze of Jun Pottery is developed from the clay glaze, prepared from the local resources and is required to be heated to around 1230 °C. There are various kinds of Jun glazes such as high glossiness glazes, matte glazes, monolayer glazes and multilayer glazes. This paper introduces formulas of several classic kinds of Jun glazes like bright glaze series, whose opacifying coatings and basic colors show good gloss. The opaci fier is mixed with the basic color glaze to take on a bright flambé effect.
