The Maison A l'Escalier de Cristal was esteablished in 1802 by the widow Mme Désarnaud, née Marie-Jeanne-Rosalie Charpentier, who managed the business. She exhibited, to great acclaim, at the 1819 Exposition des Produits de l'Industrie held at the Louvre, Paris. The business with a shop and workshop was based in the Palais Royal, a centre of excellence for the high quality jewellers, silversmiths and manufacturers of Objects de Vertu, for which Paris was renowned. The firm of l'Escalier de Cristal was the first manufacturer to mount crystal taillé objects with gilt-bronze. These were supplied by Aim-Gabriel d'Artigues (d. 1848), who in 1802 had bought the Vonche glass factory in the Ardennes, later to become the Baccarat crystalworks, and were then shipped and finished in the Palais Royal workshops. The luxury store of A l'Escalier de Cristal supplied clocks, vases, lamps and other objects d'art to ruling families in Europe, and were appointed Fournisseur breveté du Roi in 1819, as well as the Duc de Berry and the Garde-meuble de la Couronne. They dealt in and carried an extensive stock of porcelain, some of which they mounted. The company produced furniture and all kinds of luxurious objects, commissioning manufacturers to supply individual components, which were thenassembled to the firms own design, very much in the tradition of the &Imarchand merciers of the 18th century, from whom they in herited their specialist profession. In 1828 the business was led by a Monsieur Boin after Mme Désarnaud died aged 66. They later moved to premises at 162 & 163 Palais Royal. A l'Escalier de Cristal succeeded in producing objects to new designs, mainly due to Emile-Auguste Reiber (d. 1893), Christophle's chef des dessinateurs who, inspired by the arts of Japan, imitated their production techniques and adapted designs to produce stunning items for the 'hungry' European market.
