Mineralogical analysis with petrographic microscope and XRD was carried out to verify manufacturing technique of the tiles(9 samples) and kiln wall materials(5 samples) from the Anchang-ri history site in Wonju county. One of the results we found is such that during the tile manufacturing process fine tile fragments or wall materials might be added instead of chamottes to maintain tile pattern. Abandoned tiles or wall materials were recycled repeatedly, which may be supported by the recycled chamottes that made from iron-rich fine aggregates or disposed kiln wall materials in many samples analyzed. The tiles and wall materials are divided into 3 types, including low temperature type (below $800^{\circ}C$), intermediate temperature type ($800-930^{\circ}C$) and high temperature type ($930-1470^{\circ}C$) as a function of firing temperature which deduced by mineral assemblages identified under petrographic microscope and by XRD composition. Both Kiln A8 of Choseon Dynasty and wall material AW5 were burned at the highest temperature among the all analyzed samples.
