Pongsan County of North Hwanghae Province in the central part of Korea has been renowned for the production of pottery (earthenware) from olden times. With rich deposits of white clay (kaolin), the main raw material for making pottery, the county is widely disseminating the traditional pottery-making techniques and earthenware objects.
Pottery includes large pots, crocks, small jars, water jars and steamers, and the vessels for daily use include rice and soup bowls, cups, glasses, etc.
Pottery-making techniques consist of such processes as kiln furnace building, preparation of raw materials, moulding, calcination, cooling and others.
The kiln site is selected in full consideration of such places with quality clay, abundant firewood and fixed wind direction.
Raw materials are prepared by putting white clay in adequate amount of water, settling dregs, and drying them under the sunlight for 10 days before pounding on them. Then, they are moulded into various shapes before putting glaze on them. Glaze is made of wood ashes, feldspar, limestone and compounds of various metallic oxides. Calcination is done at the temperature of over 1 500 ℃ for 12 hours. Such earthenware pots are in great demand for their diverse shapes and durability.
The techniques created and developed by the Korean nation through protracted course of history have been registered as a national intangible heritage in May 2018.
