We use optical coherence tomography ( OCT ) to acquire microstructure images of C hinese Song J un glaze to reveal the copper and quartz additives used and, in two typical samples, we show that the amount added is considerable. Focusing on these two additives, including the species, amount and granule (particle) size added in the glaze, the objective of the present study is to explore how they functioned in relation to the J un glaze's visual characteristics, opalescence and sky‐blue colour, attributed to the unique liquid–liquid phase separation that occurs in J un glaze.
