摘要(Abstract)：
以福建省南平市水吉镇所产矿样为研究对象，采用XRF、XRD、TG-DTA和高温物性测试仪研究矿样的化学组成、矿物组成，以及加热过程中的变化。结果表明：该矿样主要由石英、方解石和钾长石组成，含少量滑石和褐铁矿；化学组成为Si O_2 57.87 wt.%,Al_2O_3 16.76 wt.%,Ca O 3.85 wt.%,Mg O 2.47 wt.%,K_2O 6.60 wt.%,Na_2O 0.66 wt.%,Fe_2O_3 4.43 wt.%，灼减量7.25 wt.%。矿样在加热过程中呈现出与釉料类似的熔融特征，熔融温度范围为1228～1320℃，单一组分可作釉料使用，但无法形成理想的油滴斑。
