还原剂及工艺因素对钧红分相窑变釉呈色的影响

摘要

Imitation of phase-separative Jun red furnace transmutation glaze prepared from Jingdezhen raw materials by modem porcelain making techniques was fired in the shuttle kiln. The products basically reached the varied lustre effects of blue and purple. The influences of the technical factors on the coloration of phase-separative Jun red furnace transmutation glaze, such as the reductants of SnO2 and FeA. The glazing thickness, and the initial reducing temperature, were analyzed by colorimeter and field emission electron microscopy.%采用现代制瓷工艺,选用景德镇附近所生产的陶瓷原料,在梭式窑中烧制的钧红分相窑变釉,基本达到了其深浅不同的青蓝色流纹与紫红色交相辉映的效果,并借助色度计、SEM等手段,主要探讨了还原剂SnO2、Fe2O3及施釉厚度、还原起始温度等工艺因素对钧红分相窑变釉呈色的影响.
