The Cross of Lorraine was used by artisans working in and around Nancy which became famous for its art glass and crystal during the Art Nouveau period. Amongst Nancy's most reknown names in glassmaking were Daum and Galle. Cameo glass is a luxury form of art glass produced by cameo etching and carving through fused layers of differently coloured glass to produce designs. In the French Art Nouveau designs all of the top layer except the areas needed for the design were removed by an acid etching process. Areas were covered with a resist layer such as wax and the glass was repeatedly dipped in acid. Detailed work was then done with wheels and drills before finishing.
