Yinliuzhai shuoci 飲流齋說瓷 is a book on porcelain written written during the early Republican period (1920s) by Xu Zhiheng 許之衡 (1877–1935), courtesy name Shoubai 守白, from Panyu 番禺, Guangdong.
The text consists of 2 juan with ten chapters that give an overview of the topic and explain details of the production process, like the kilns, glazing, painting, marks (kuanzhi 款識), various types of vessels, and how to detect flaws and forgeries (ci wei 疵偽). Xu's book is, in spite of several errors, very helpful for the classification and appreciation of ancient porcelain.
It is found in the series Meishu congshu 美術叢書.
