Manganese Dioxide Reduction Kiln
Jun kiln | Chinese Porcelain, Ming Dynasty, Ceramics
Jun kiln, Chinese kiln known for the stoneware it created during the Northern Song period (960–1126) in Junzhou (now Yuzhou), in northern Henan. One class of glazed wares produced at the kiln consisted mostly of opalescent blue pieces (ranging from grayish blue to a plum colour), many strikingly splashed or mottled in purple or crimson.

Selective Recovery of Zn and Mn from Waste Zinc–Manganese …
As shown in Fig. 2a and b, manganese oxides were gradually reduced in the sequence MnO 2 → Mn 2 O 3 → Mn 3 O 4 → MnO → Mn. The reduction process of MnOx → MnO could be easily realized at low temperatures in systems containing C and CO–CO 2. However, further reduction of MnO to Mn required higher conditions.
