透明裂纹釉影响因素的探究

本项目以较好的透明裂纹釉配方为基础，考察其釉料组成、工艺参数和烧成制度等对釉面效果的影响。实验结果证明：较好的组成范围是，钠长石为70-78wt.%，高岭土1-3wt.%，石英12-20wt.%，石灰石6-12wt.%；烧成温度为1290℃，保温30 min，冷却速度20℃/min；釉层厚度为0.8~1.3 mm，球磨时间是20 min。所得样品釉面光滑平整、透明度较好，裂纹也具有较好艺术效果。

Factors Inlfuencing Transparent Crackle Glaze

The effects of glaze composition, process parameters and firing systems on glaze result were studied for a better formula of transparent crackle glaze. Experimental results show that the preferable range of the composition is sodium feldspar 70 ~ 78 wt%, kaolin 1 ~ 3 wt%, quartz 12 ~ 20 wt%, limestone 6 ~ 12 wt%; ifring temperature is 1290℃, holding time is 30min, cooling rate is 20 ℃/min; glaze layer thickness is 0.8 ~ 1.3 mm, and the milling time is 20min. The glaze surface of the resulted samples was smooth with better transparency and artistic crackle effect.
