In 1912, due to increasing demand, the company expanded and took on the new name Könitz Porcelain Factory Gebrüder Metzel.
At the end of World War II, Könitz was considered one of the leading medium-sized porcelain manufacturers in Germany.
Under new direction and under the original Könitz brand name, the production of household porcelain goods resumed.
The company rejoined the international market, shipping goods to the Netherlands, Israel, Italy, Norway, Austria, and the United States.
At the beginning of the 1970s the name "KÖNITZ" disappeared for nearly 20 years from the backstamp while other porcelain producers, e.g. Volkstedt, Uhlstädt, Garsitz near Königsee and Langenberg in Gera incorporated to Kombinat Kahla.
Along with extensive investment and rebuilding measures, i.e. the purchase of the new decorational fire stove in 2008, Könitz developed its position in the international market much more steadfast.
