The spread history of blue and white porcelain bottles in Hongguan kiln.
Yan 'an Xinhua Ceramics Factory was originally funded directly by the Central Committee of the Communist Party of China, and organized technicians and craftsmen to set up in Yan 'an Dongshilipu. It is the first "* * * camp" porcelain factory founded by our party before the founding of the People's Republic of China. At that time, it mainly produced pots, bowls, cups, plates, cans, altars and other daily necessities needed by the soldiers and civilians in the border areas, as well as munitions such as mines, electromagnetics and detonators. The ceramic factory also burned some vase ornaments and other ornaments on the head to decorate the family at the wedding. At that time, the products fired by the factory had not yet been circulated in the market, so the vases were only "luxury goods" of the head of state at that time, because the blue and white materials and glazes at that time were patriotic overseas Chinese and white glazes. In view of the special historical role of Yan 'an Xinhua Porcelain Factory in War of Resistance against Japanese Aggression, the anti-encirclement campaign and the mass production movement, it should be worthy of the name "Red Official Kiln".
