The city of Vierzon saw its notoriety rise at the same time as the industries developed on its territory. At the beginning of the 20th century, it counted nearly 14 porcelain factories in which about 1500 workers worked. The industrial development of Vierzon was made possible by its favorable natural environment (wood, clay) and by the development of railway (1847) and fluvial transport which allow the rapid supply of raw materials (coal) but also the export of manufactures. The Taillemite factory was founded in 1875 by François-Xavier DARMET (1843-1911) a Viennese who was also successively mayor of Vierzon-Village and member of the General Council of Cher. The manufacture mainly made porcelain for the hotel industry and medium-range table services. On the death of DARMET, the factory was bought by Lucien TAILLEMITE (1880-1937) who continued production during the First World War. It is especially his son Roger (1909-1981) who transforms it into one of the largest porcelain manufactures in France. He will never stop, for nearly fifty years to modernize and facilitate the work of these workers. Roger TAILLEMITE pursued a policy of diversification. While continuing to serve the hotel business which represents half of his turnover, he creates new sets including a set "Chasse" which was a great success. He is also president of the Chamber of Berry Porcelain Manufacturers and vice-president of the National Union of French Porcelain. Thirteen production units shut down in Vierzon between 1952 and 1970. To face the competition a grouping is organized around Taillemite Establishments, in partnership with the Saint-Genou plant (Indre) and the Jacquin factory in Vierzon: the Compagnie Nationale de Porcelaine was born (CNP). A new merger was made in 1969 with Union Limousine, a high-end tableware factory in Saint-Léonard-de-Noblat. The plant being in Haute-Vienne, its production has the right to be stamped "Limoges" and its good profitability brings a breath of fresh air to the CNP. However, the following years marked the decline of the NPC, accelerated by unstable partnerships with the United States (oil shock) for example. CNP filed for bankruptcy in 1983. It was taken over by Jean-Pierre LEMAN, director of the Saint-Genou subsidiary who took charge of the creation, and Daniel Cohen of Lara, consulting engineer, who deals with finance and sales. They profoundly modify the structure of the factory: modernization of the techniques and reduction of the personnel (from 550 workers one passes to 240). In spite of all this the hope to constitute in Berry a great international group moves away. Then, Vierzon does more than decorate the white porcelain of Saint-Genou and this studio of decoration stops its production in January 1997, sounding the death knell of the porcelain vierzonnaise.
