This factory was created by the direction of the faience manufacture of Nimy located to Mons in Belgian Hainaut and which existed since 1789. The purpose of this new establishment was to avoid the loads due to the export of Belgium towards France as towards the other countries of the world because the loads of export in France were weaker than in Belgium. It is then built on a property belonging to Joseph Clerquin on a surface of +-13000 m2. This property will not cease growing to be in 1938 at the end of the exploitation of +-64000 m2 and will employ at this time from 450 to 500 workers and workmen.
 

Isidore Paulus, wire of the director of the Faience manufacture of Nimy and painter on earthenware, were the first director of 1821 to 1827.

April 27, 1858 Jean Mouzin Baptist, (Director of the manufacture of Turned), his brother Jean Pierre Mouzin (ex-director of Louvière and director of the Faience manufacture of Nimy since 1851) and Theophilus Lecat (associate of Mouzin to the Faience manufacture of Nimy) repurchase the Faience manufacture of Onnaing with Alexandre Giraud and constitute a partnership “the Company Mouzin Frères and Co”

14 the Mars the 1894 “Company Mouzin Frères and Co” is transformed into “Limited company of the Faience manufacture of Onnaing”.

After the German destruction in 1918, manufacture will take again on May 17, 1921, to cease on February 8, 1938. The company enters then in liquidation on August 17, 1939, until the end of the year 1947, under the responsibility of Edouard Hans.
 

The Faience manufacture of Onnaing, towards the end of the 19th century, makes great strides growing thanks to the rail-bound transport facilitating the contribution of the raw materials. At that time the modellers, who are true artists having been formed at the academic schools of Valencians create models of jugs representing of the politicians such as Déroulède, Poincaré,… but also of the characters known as the Alsatian one, Francisco Ferrer (teacher shot in Spain), Marianne, Jeanne d' Arc,… of the jugs feminist symbol the jupe Culotte as well as models of imagination such as fish, the monk, the duck, the Main pig of hotel,… The floral jugs are not remains about it, they are even in my opinion of realisation more complete and harmonious like the jug Tango, Mille fleurs, Chrysanthème, Cyclamen, Giroflées, Capucines, Iris, Oeillet,… the barbotine parts like general public what allows a considerable production in order to satisfy the local but so foreign customers. The production out of barbotine is more and more diversified creations of vases, flowers stand, covers, quills, jugs of form, moneyboxes, services of smokers, ashtrays, centres of tables, columns, bouquetières are very numerous. Each year, 5 new models of jugs are created.
 

Unfortunately in 1914 the First World War is declared. E at the end of 1918 the renewal of activity of the Faience manufacture of Onnaing will be quite difficult because the madness of these moments ransacked all the equipment of Faience manufacture (Moulds, mixers, crushers, mixers, filters, boilers, etc). In spite of superhuman efforts, goodwill and energy to maintain the production, this one stops on February 8, 1938.
