Associated with water and spring rebirth, the enduring dragonfly is embossed onto the La Rochere Dragonfly 7-1/2-Inch Plate. As a symbol, the dragonfly has been around for many centuries. La Rochere glassware is clear and beautiful for the dining room, sturdy enough for every day use, and dishwasher safe. The oldest glass factory in France, La Rochere was founded in 1475, seventeen years before Christopher Columbus set foot in the Americas. Adorned with raised relief decorations that symbolize France, each pattern of La Rochere glass is a timeless classic. Uniquely clear, La Rochere glassware is produced by melting, at around 1450 degrees C, a mixture of sand, soda, and lime to create silico-sodocalcic glass. Various other elements are added to refine and improve brilliance to create heavy-duty glassware that's perfect for every day use and special occasions.
