(1918 - 1945) Between two wars at the Earthenware factory of Longwy with d'Huart
The work of the Factory resumes during the conflict and its activity will be again booming from 1923 with the "Art Deco" movement that will be inspired by Raymond Chevallier. Orders from Parisian department stores such as "PRINTEMPS" (stamp PRIMAVERA) and "LE BON MARCHE" (stamp POMONE) will give a new impetus to the factory which will have more than four hundred and fifty workers.
The production at the end of the war is still with forms and decorations resumed production 19th but lower quality for all comers. We can note the D792 decor that will be reworked to have less enhancement to do but will be reduced to its elegance 19th. Indeed the passage in joint stock company of the Faïencerie of the brothers d'Huart in 1901, which until then was in collective name, will allow them to increase the capital for a refocusing of the productive activity to the detriment of the creativity.
The production of earthenware will continue with table services which will mostly be stained with simplistic decorations but also a "brocatelle" production refined by its sometimes naive decorations.
But the economic crisis of the 1930's crushes orders and the second world war will be the cessation of production because of war. The production activity of Factory restarted in 1941, in the castle management with twenty or so workers who are mainly engaged in the production of enamelled pieces.
