The porcelain kiln operated in Chosun Dynasty was horizontal draft type or half down draft type
incline kiln. It was inherited from the porcelain kiln of Koryo Dynasty. Considering the process from an
installation to burnability, the attribution of the porcelain kiln is classified into the location, construct
form, construct material, pre-kiln facilities, entrance of firing place, elevation shape of a firing place,
firing place stair, kiln size, elevation shape and aspect shape of a combustion chamber, finishing method
of a combustion chamber floor, inside facilities of a combustion chamber, biscuit firing chamber, side
entrance and disuse place, chimney, ceiling, repair and reconstruction of a kiln, burnability method and
kiln tools. From among these, elevation shape of a firing place, height of firing place stair of a firing
place, kiln size, elevation shape and aspect shape of a combustion chamber, inside facilities of a
combustion chamber, biscuit firing chamber, burnability method and kiln tools are attributions which
show specific change as time passed. Analyzing these, the porcelain kiln of Gyeongsang Province is
divided into 12 types from the 15th to the 19th century.
To sum up, the ceramic industry of Chosun Dynasty in Gyeongsang Province is divided into 5 phases
totally. The first phase corresponds from the first quarter of the 14th century to the second quarter of the
15th century. The AⅠ1 type kiln was operated. The second phase corresponds from the third quarter to
the fourth quarter of the 15th century. The AⅠ1, AⅡ2, BⅠ1, BⅠ2 type kiln was operated. The third
phase corresponds from the fourth quarter of the 15th century to the fourth quarter of the 16th century.
The BⅠ2, BⅡ1, BⅡ2, BⅢ2 type kiln was operated. As grayish-blue-powdered celadon product
changes to white porcelain product, various changes appear in the structure of kiln. The fourth phase
corresponds from the first quarter of the 17th century to the second quarter of the 18th century. The CⅢ
2, CⅢ3, CⅣ1, CⅣ2 type kiln was operated. The fifth phase corresponds from the fourth quarter of the
