05 not detected -
06 not detected There are a large number of
hemispherically-shaped pits on the glaze surface and

some yellow substances in the cracks.
07 not detected
There are a lot of white spots on the ridges and rim, which proved to be
corrosion craters.

08 quartz, anorthite, diopside It can be found in the manuscript.

09 quartz, anorthite, diopside, quintinite 1190
10 -
There are densely spaced plate-like anorthite crystals in the glaze and the
surrounding glass phase was corroded, showing a porous structure.

* XRD was applied to the glaze surface of the samples.
** The firing temperature of the bodies was examined by dilatometer, and the method can be seen in Method section of the manuscript.
*** The sample has not been tested.
