His renowned glassmaking is the result of a continuous technical improvement. He decorated the glass surfaces with large applications that provided a three-dimensional realism to flowers and fruits without weakening the piece. In 1898 he gets a patent for the inlaid glass (marquèterie de verre) made by injecting small inclusions in the melting paste. His most outstanding pieces were carved when the work of glass or crystal was achieved.
Before the industrial era reached his workshop, each piece was unique but he nevertheless had preferred themes for literary, poetic, social or patriotic purposes. Around 1900, the rose of France illustrates some of his most complex glasswares. This Rosa gallica has a reputation for being in France for centuries, but in a territory limited to a region near Metz which was part of the Alsace-Lorraine then annexed by the Germans.
