Recalling those days, Chen laughs wryly: "You've got the physics involved in dealing with ceramic clays, the chemistry of glazes, and then you add problems with controlling the heat, which seem resistant to scientific control. Adjusting slightly the ingredients in the glazes or the heat and firing times-even only by a few seconds-can lead to entirely different coloration."
回想那段日子，陳立恒苦笑表示：「物理性的瓷土結合化學性的釉藥，卻是由無法完全科學化控管的『火』來掌控；釉藥的調配、窯燒時發色的時間和溫度，有時只是幾秒的誤差，成品的色澤就有天壤之別。」
