The invention relates to a preparation process of overglaze decoration powder celadon. The powder celadon comprises a green body, lavender grey glaze and a color material, wherein the lavender grey glaze is prepared from the following raw materials: Dehua quartz, szaibelyite, asbestos powder, Dehua kaolin, Zijin clay, frit and yttrium oxide, the prepared powder celadon is dark green and elegant in glaze color, the pink white is shown in dark green, the glaze surface is soft and fine in gloss, the raw material composition of the lavender grey glaze is precisely limited, the chemical components of the frit are strictly controlled, and the Zijin clay is introduced to be matched with the frit, so that the glaze surface of the fired porcelain is pink green; the szaibelyite is introduced to be matched with yttrium oxide, so that light refraction of the glaze is increased, the glossiness of a glaze surface is improved, and the glaze surface is soft and fine in glossiness; and asbestos powder is introduced to reduce crystal water and carbonate radicals in the raw materials so as to reduce steam pockets in glaze slip, so that the glaze layer is enabled to be compact and fine.
釉上彩粉青瓷的制备工艺，所述粉青瓷包括坯体、粉青釉和彩料；粉青釉由以下原料组成：德化石英、硼镁石、石棉粉、德化高岭土、紫金土、熔块、氧化钇，本发明制备的粉青瓷釉色青绿淡雅、青绿中显粉白，釉面光泽柔和、细腻，该粉青瓷精确限定粉青釉的原料组成，并对熔块的化学组分进行严格的把控，引入紫金土与熔块配合，以使烧制后的瓷器釉面呈粉青；引入硼镁石与氧化钇配合，以增大釉对光的折射，提高釉面的光泽度，是釉面光泽柔和、细腻；引入石棉粉来降低原料中的结晶水及碳酸根来减少釉浆中的汽包，使釉层致密、细腻。
