废瓷粉在梅子青裂纹釉的应用研究

The Application of Waste Porcelain Powder in Preparation of Crackled Plum-green Glaze

采用韩国当地原料及废瓷粉制备梅子青裂纹釉。为了改善釉面针孔及解决当地废瓷大量堆放等问题,考察废瓷粉含量对梅子青裂纹釉的影响。研究结果表明:随着废瓷粉含量的增加,釉面的裂纹逐渐由稠密向稀疏直裂纹转化,釉面梅子青色调变淡。当废瓷粉含量为3%时,釉面呈现交叉网状的细碎裂纹,梅子青色调并具有玉质感。这主要是由于釉中析出石英晶相,并且釉中有许多的小气泡存在,对光造成了漫反射和散射,因此釉面呈现玉质感。该研究结果不仅拓宽了废瓷粉在青瓷釉中的应用,而且利于保护环境,节约生产成本。

Abstract： The crackled plum green glaze was prepared by using Korean materials and waste porcelain powder. Effects of waste porcelain powder concentrations on the properties of the crackled glaze were studied to seek to solve the pinholing of the glaze and to recycle the pileup of porcelain debris. The results showed that with the increase of the waste porcelain powder concentration, the green color became lighter, and the crackles were more sparsely distributed. When the waste porcelain powder concentration was 3%, the glaze exhibited jade-like texture in plum-green shade with small crackles due to the presence of many gas bubbles and unmelted quartz phases in the glaze. The study not only broadens the application of waste porcelain powder in celadon glaze preparation, but also is benefcial for production cost saving and environmental protection.
