The Path to Porcelain: Innovation in Experimental White Stoneware from Luoyang

Multiple-analytical study on the initiation and technology of Zhaili celadon from the late sixth to the seventh centuries

“…and TiO2. The Fe2O3 contents of Zhaili glazes are clustered in a region of 1.84 wt.%-4.82 wt.%, averaging 3.13 wt.%, which is obviously higher than the other contemporary glazes produced in the Xing kiln, Ding kiln (Cui et al, 2012, Lu et al, 2012, Huang et al, 2020, Huang et al, 2023. The TiO2 of Zhaili celadon are also in high contents, ranging from 0.72 wt.% to 1.60 wt.%, with an average of 1.00 wt.%.…”

“…The irregular shape and the coarse size of the quartz indicate they are likely to be extrinsic to the clay. Bright particles of TiO2, probably derived from rutile or anatase in the clay (Huang et al, 2023), are general in the body. The pores in body are irregular and fine.…”

“…However, as shown in Fig. 3c, 3d, the grains of quartz are coarse and angular which can interpret as a material, such as crushed quartz pebbles or milled sand (Huang et al, 2023), thus we prefer the deduction that additional quartz was added.…”
