The samples JQA.SH1, FQB.SH3, PQC.SH5 and NQD.SH7, showed that phase structure were quartz, tridymite and mullite phase. It was confirmed that sherds were fired at high temperature more than 1000 °C. As a result, they made the body and glaze compacted and turned into stoneware at high temperature. SEM images of surface showed the middle layers between glaze and body for JQA.SH1 and FQB.SH3.
