In a departure from their embossed motifs, La Rochere proudly offers Perigord glassware featuring facetted cut motifs and the addition of a knob stem. The Perigord style is also durable, dishwasher safe, and wonderfully clear, brilliant glass. 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 products are produced by melting, at around 1450 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. Goblet dimensions: 4" x 7", 15.5 oz. capacity. Single Goblet
